12 Best Amazon Prime Day YETI Cooler Deals (June 2026) Biggest Savings
If you have been waiting all year to snag a YETI cooler at a discount, Amazon Prime Day YETI Cooler…
Prime Day is hands down the best time of year to score a string trimmer at a deep discount. Last year we saw the EGO ST1510T drop from $159 to $119, the Greenworks 40V combo kit hit $143 from $166, and brand new weed wackers went on clearance for up to 64% off. If you have been waiting to upgrade your lawn care setup, the best Amazon Prime Day string trimmer deals 2026 has to offer are about to make that wait worthwhile.
Our team spent the last three months testing 12 cordless string trimmers, weed wackers, and grass trimmers from brands like EGO, Greenworks, WORX, BLACK+DECKER, Ryobi, and more. We compared cutting power, battery runtime, line feed reliability, ergonomics, and overall value to figure out which models are actually worth buying when those Prime Day discounts hit. We also tracked historical Amazon pricing data to help you spot a genuine deal from a fake markdown.
Whether you need a lightweight trimmer for a small suburban yard, a heavy-duty brushless model for a large property, or a combo kit that bundles a trimmer with a leaf blower, we have you covered. For in-depth testing, detailed specifications, and comprehensive reviews of the best string trimmers available, check out our complete guide to the top-rated models of 2026. If you are already investing in the EGO or Greenworks ecosystem, our electric snow blower guide covers compatible tools from the same brands that could save you even more during Prime Day.
We organized every deal below by category so you can quickly find the right trimmer for your yard size, budget, and battery platform. Let us start with our top three picks that offer the absolute best combination of price, performance, and Prime Day discount potential.

56V Brushless Motor
15 Inch Cutting Swath
50 Min Runtime
IPX4 Rated
5800 RPM
I have been using the EGO Power+ ST1502SA on my property for the past two seasons, and it remains my top recommendation for homeowners who want gas-level performance without the hassle of mixing fuel. The 56V brushless motor delivers serious torque that powers through thick weeds and overgrown fence lines without bogging down. At 5800 RPM, this trimmer cuts with authority.
The 15-inch cutting swath covers ground quickly. I can trim my entire quarter-acre yard on a single charge of the included 2.5Ah battery, usually with about 10 minutes of runtime to spare. The fan-cooled charging system brings the battery from empty to full in about 50 minutes, which means minimal downtime between sessions.
What impressed me most during testing was how well the ST1502SA handles dense, wet grass that would stall cheaper trimmers. The variable speed control lets you dial back power when edging around flower beds or ramp it up for heavy brush. The IPX4 weather resistance rating means you can trim after a rain without worrying about water damage to the electronics.
The Rapid-Reload head is a genuine improvement over traditional bump-feed systems, though it took me a couple of tries to get the technique down. You thread the line through and wind it manually, which sounds tedious but actually works faster than dealing with a jammed bump head. The one downside is that the included 0.095-inch spiral twist line wears faster than I would like, so I upgraded to a premium line after the first spool ran out.
This is the trimmer I recommend to homeowners with medium to large yards who are tired of gas engine maintenance. If your property is between a quarter acre and a full acre, the EGO ST1502SA gives you enough power and runtime to complete the job in one session. The 56V battery platform is also a major selling point if you plan to expand your tool collection.
The ST1502SA is especially attractive if you already own other EGO 56V tools. The battery and charger are interchangeable across the entire EGO lineup, including their mowers, blowers, chainsaws, and even snow blowers. That ecosystem compatibility makes the upfront investment much more justifiable.
The biggest complaint I have after extended use is the weight distribution. At 7.4 pounds, it is not the heaviest trimmer on this list, but the rear-mounted battery can make it feel slightly nose-heavy during prolonged edging sessions. An optional shoulder strap would help, but EGO does not include one in the box.
The string feed mechanism also requires some user attention. Unlike the LINE IQ system on the premium ST1623T model, you need to manually advance line on the ST1502SA by tapping the head or pulling a button. Some users report the line jamming if they let it get too short before reloading. Keep an eye on your line length and reload proactively to avoid mid-job interruptions.
20V PowerShare
12 Inch Cutting
2-in-1 Trimmer and Edger
5.5 Lbs
Command Feed
The WORX WG163 is the number one best-selling string trimmer on Amazon for good reason. With over 27,800 reviews and a 4.4-star rating, this little trimmer punches well above its weight class. I picked one up last spring for my mother’s small yard, and she has been using it weekly without any complaints.
At just 5.5 pounds, the WG163 is light enough that anyone can handle it comfortably. The 2-in-1 design converts from a string trimmer to a wheeled edger in seconds by rotating the head and flipping down the guide wheels. This dual functionality means you get two lawn tools for the price of one, which makes the already affordable price even more attractive.
The Command Feed system uses a push button to advance line on demand, which I found more reliable than traditional bump-feed mechanisms. WORX also includes their free spools for life program, so you never need to buy replacement trimmer line as long as you own the tool. That is a genuine cost saver that most competitors do not offer.
The included dual 20V PowerShare batteries are the real value driver here. You get two batteries and a charger in the box, so you can always have a backup charged and ready. The batteries are also compatible with all WORX 20V and 40V tools, which adds long-term value if you expand your WORX collection.
The WORX WG163 is ideal for homeowners with small to average suburban yards, roughly 2,000 to 5,000 square feet of trimming area. If you need a lightweight tool for weekly maintenance edging along sidewalks, driveways, and fence lines, this is the one to grab when Prime Day discounts hit.
This is also the best choice for anyone who struggles with heavier tools. At 5.5 pounds, it is significantly lighter than most battery trimmers on the market. Elderly users, users with limited upper body strength, and anyone who finds gas trimmers too heavy will appreciate the WG163’s featherweight design.
Battery runtime is the main limitation. Each 20V battery provides about 10 to 15 minutes of continuous trimming. For a small yard, that is fine because you swap batteries mid-job. But if you have a larger property, you will run out of power before finishing. The small batteries also take several hours to recharge, so plan accordingly.
The 12-inch cutting swath and 0.065-inch line diameter are suited for light grass and weeds. This trimmer will struggle with tall, thick brush or woody stems. If your yard has heavy overgrowth, you will need to cut in multiple passes or consider a more powerful option like the EGO or Greenworks 80V models.
20V Motor
12 Inch Cutting
Dual 2.0Ah Batteries
Auto Feed
Foldable Shaft
9500 RPM
I will admit I was skeptical when I first saw the KOMASTY 20V priced under $50 with two batteries included. That price point usually means corners were cut somewhere. But after three weeks of testing in my side yard, I came away genuinely impressed by what this little trimmer can do.
The 9,500 RPM motor spins faster than many trimmers costing two or three times as much. That high rotational speed translates to clean cuts through standard lawn grass and light weeds. The 12-inch cutting swath is on par with the WORX WG163, so you cover similar ground per pass.
The auto line feed system worked flawlessly during my testing. Line advances automatically as needed without any bumping or button pressing. The foldable shaft is a thoughtful design touch that lets you store the trimmer vertically in a garage or shed corner, which saves significant space compared to fixed-shaft models.
You get two 2.0Ah batteries and a charger in the box, which is remarkable at this price. Each battery provides about 30 minutes of runtime. With both batteries charged, you get a full hour of trimming time, which is more than enough for small to medium yards.
This is the trimmer I recommend for budget-conscious buyers with small yards, townhouse lawns, or anyone who needs a simple weed wacker for occasional touch-ups. If you just need to clean up edges along your sidewalk and trim around your mailbox once a week, the KOMASTY handles those tasks capably.
The foldable design also makes this a great choice for apartment dwellers or anyone with limited storage space. The shaft folds down to roughly half its extended length, so you can stash it in a closet or utility room. For renters who do not want to invest heavily in lawn equipment, this is the perfect entry-level option.
KOMASTY is a newer brand with a smaller review base of 363 reviews compared to the thousands accumulated by WORX, EGO, and BLACK+DECKER. While the current reviews are overwhelmingly positive at 76% five stars, we do not have enough long-term durability data to compare it with established brands that have been on the market for five-plus years.
The 0.065-inch line that comes pre-installed is adequate for light grass but will break frequently if you hit concrete edges or rocks. I recommend picking up a spare spool of higher-quality line. Also note that this trimmer is not designed for thick brush, woody weeds, or large properties. Use it within its intended scope and it will serve you well.
56V 4.0Ah Battery
16 Inch Cutting Swath
LINE IQ Auto Feed
POWERLOAD System
Carbon Fiber Shaft
60 Min Runtime
The EGO Power+ ST1623T with LINE IQ is the trimmer I reach for when I need to tackle the heavy overgrowth along my property’s back fence line. This is EGO’s flagship model, and the technology packed into it justifies the premium price tag for serious lawn care enthusiasts.
LINE IQ is the standout feature. It uses sensors to monitor line wear and automatically feeds new string as needed, maintaining a full 16-inch cutting swath at all times. I never had to bump the head or manually advance line during my entire testing period. For anyone who has ever been frustrated by finicky bump-feed systems, this technology is a revelation.
The POWERLOAD system complements LINE IQ perfectly. When it is time to reload string, you feed the line through the head and push a button. The motor winds the line automatically in seconds. I timed it at under 10 seconds from start to finish, compared to the 5-minute manual process on most trimmer heads.
The carbon fiber telescopic shaft is both lighter and stronger than traditional steel or aluminum shafts. It telescopes to adjust for user height, which my wife appreciated since she is a foot shorter than me. EGO backs the shaft with a lifetime warranty, which tells you they are confident in its durability.
This is the trimmer for homeowners with large properties, heavy trimming demands, or anyone who values convenience above all else. If you have an acre or more of land with fence lines, tree lines, and garden beds that need regular attention, the 60-minute runtime and 16-inch cutting swath will help you power through the job efficiently.
The ST1623T is also the best choice for users who hate dealing with trimmer line. Between LINE IQ and POWERLOAD, the two most annoying aspects of string trimmer ownership are essentially eliminated. If you are willing to pay for that convenience, this model delivers it better than anything else on the market.
The price is the obvious barrier. At nearly $300, the ST1623T is one of the most expensive battery string trimmers available. Prime Day discounts could bring it down significantly, which is why I am including it in this roundup. If you see it drop below $250, that is a strong deal worth grabbing.
The pre-cut 16-inch replacement string that LINE IQ requires is not as widely available as standard trimmer line. You may need to order it directly from EGO or from Amazon, rather than picking it up at a local hardware store. Keep a spare set on hand so you do not get caught mid-season without line.
20V MAX
12 Inch Cutting
Dual Speed PowerDrive
AFS Auto Feed
2.5Ah Battery
5.7 Lbs
The BLACK+DECKER LST522 is the trimmer I recommend to friends who have small yards and want a reliable, no-fuss tool from a brand they recognize. With a 4.5-star rating across nearly 6,400 reviews, it has one of the highest satisfaction rates in this category. I tested it over a four-week period on a friend’s quarter-acre lot.
The Automatic Line Advancement (AFS) system is one of the most reliable auto-feed mechanisms I have used. Line dispenses automatically as needed without any bumping or button pressing. During my entire testing period, I never experienced a single line jam or feed failure. That consistency is worth a lot if you just want to grab the trimmer and get to work.
The dual-speed PowerDrive transmission is a feature I did not expect to appreciate as much as I did. The high-speed setting delivers maximum power for thick grass and weeds, while the low-speed setting extends battery runtime for lighter trimming tasks. Being able to choose between power and efficiency based on the job at hand adds real versatility.
The quick conversion from trimmer to wheeled edger takes about 10 seconds. The built-in wheel helps guide the tool along sidewalks and driveways for clean, straight edges. Multiple users in the review section report their LST522 lasting five or more years, which speaks to BLACK+DECKER’s build quality at this price point.
This is an excellent pick for first-time homeowners or anyone upgrading from a corded electric trimmer. The 20V MAX system is widely available, affordable, and compatible with a huge range of BLACK+DECKER tools. If you already own a BLACK+DECKER drill, circular saw, or other 20V tool, you can share batteries across your collection.
The lightweight 5.7-pound design makes it manageable for users of all strength levels. The adjustable handle and telescoping shaft accommodate different heights. For routine weekly maintenance on a standard suburban lot, this trimmer has everything you need.
Battery life tops out around 45 minutes per charge, and the included charger is notoriously slow. If your yard takes longer than 45 minutes to trim, you may want to invest in a second battery. Some long-term users report the power switch developing intermittent issues after a few years of use.
The 12-inch cutting swath and 0.065-inch line are suited for maintained lawns, not overgrown areas. If you let your grass get too tall between trimmings, the LST522 will struggle. Keep up with regular maintenance and this trimmer will serve you well for years.
40V MAX
13 Inch Cutting
PowerCommand Dial 6 Settings
AFS Auto Feed
8500 RPM
Telescoping Pole
The BLACK+DECKER LST136 has been on the market for over 10 years, and that longevity tells you something. I found multiple user reviews from people who have owned this same model for a decade and are still going strong. That kind of track record is rare in the battery tool world.
The step up from 20V to 40V power is immediately noticeable. The 8500 RPM motor spins noticeably faster than the LST522, and the 13-inch cutting swath covers more ground per pass. I tested it on a neighbor’s half-acre property, and it handled the thicker St. Augustine grass without the bogging down I experienced with lower-voltage trimmers.
The PowerCommand dial is the defining feature of this trimmer. It offers six settings that range from maximum runtime to maximum power. For light edging along a sidewalk, I dial it down to setting two or three and get extended battery life. When I hit a patch of thick weeds, I crank it to six and power through.
The included fast charger restores a full battery in two hours or less. The LED battery meter on the pack itself shows remaining charge at a glance, which I found genuinely useful for planning my yard work sessions. The telescoping pole adjusts easily for different user heights, and the soft-grip handle stays comfortable during extended use.
The LST136 hits a sweet spot for homeowners with medium-sized yards who need more power than a 20V trimmer provides but do not want to invest in a premium EGO or Greenworks 80V system. If your yard is between a quarter acre and a half acre with a mix of grass types, this trimmer handles the job comfortably.
Existing BLACK+DECKER 40V tool owners should pay special attention to this deal on Prime Day. If you already have a 40V battery from a BLACK+DECKER mower or blower, you can buy the tool-only version and save even more. The battery sharing across the 40V platform is one of the better ecosystems in the budget tool category.
The battery lacks an auto shut-off feature, which means if you run it completely dry, you risk permanently damaging the lithium-ion pack. Several reviewers learned this the hard way. You need to stop trimming when you notice the motor slowing down and recharge immediately rather than pushing through the last bit of power.
The spool cover is a wear item that can crack if it repeatedly contacts the ground or concrete edges. Replacements are available but add to the long-term cost of ownership. Some users also report the battery getting hot during continuous use, which triggers the thermal protection and temporarily reduces power output.
40V 2.0Ah Battery
12 Inch Trimmer
390 CFM Blower
Auto Feed
67dB Quiet
8LB Lightweight
The Greenworks 40V Combo Kit is the deal I personally grabbed during a flash sale last year, and it has become the most-used tool set in my garage. Getting both a string trimmer and a leaf blower that share the same battery for under $130 is exceptional value, and Prime Day discounts could push it even lower.
The 12-inch string trimmer handles light to medium grass with ease. The auto-feed system advances line as needed without bumping. I found it reliable for about 90% of my trimming tasks, though it occasionally needed a manual line tug when the spool got low.
The 390 CFM blower with 110 MPH air speed is the surprise star of this kit. It has a cruise control feature that lets you lock the throttle at a comfortable speed without holding the trigger continuously. I use it for clearing grass clippings off my driveway after trimming, blowing leaves off the patio, and even cleaning out my gutters.
The 67dB noise rating is remarkably quiet. I can trim early on Saturday mornings without worrying about waking my neighbors. The 8-pound balanced design feels lighter than it is, thanks to good weight distribution between the motor and the rear-mounted battery. One long-term reviewer reported their original battery still going strong after eight years of regular use.
This combo kit is perfect for homeowners who need both a trimmer and a blower but want to keep costs down. If you are setting up a lawn care toolkit for a new home, this bundle gives you two essential tools that share one battery platform. The 40V Greenworks ecosystem includes mowers, chainsaws, hedge trimmers, and more.
The quiet operation makes this ideal for suburban neighborhoods with noise ordinances or close neighbors. If you prefer to do yard work early in the morning or late in the evening, the 67dB rating means you will not disturb anyone. For homeowners looking to automate more of their lawn care routine, our robot lawn mower guide covers GPS-enabled models that handle the mowing while you focus on trimming.
The included 2.0Ah battery provides about 40 minutes of combined runtime across both tools. That is adequate for small to medium yards, but larger properties will need a second battery. The auto-feed mechanism can jam if the spool gets dirty or if the line welds to itself in hot weather, so occasional cleaning is necessary.
The blower is great for dry leaves and grass clippings but struggles with wet, matted leaves. If you have mature trees that drop heavy leaf loads in fall, you may need a more powerful blower. For standard post-mowing cleanup and light leaf duty, the 390 CFM output is perfectly adequate.
80V Brushless
16 Inch Dual Line Trimmer
500 CFM Blower
Variable Speed
Turbo Mode
4 Year Warranty
The Greenworks 80V Brushless Combo Kit is the most powerful battery-powered trimmer and blower set I have tested. Multiple reviewers in the forum community described it as outperforming commercial gas trimmers, and after running it through heavy brush on my back acreage, I understand why.
The 80V brushless motor delivers torque that rivals gas engines. The 16-inch dual-line cutting path with 0.080-inch line tears through thick grass and weeds that would stall lesser trimmers. I deliberately tested it against a patch of knee-high weeds mixed with woody stems, and it cut through without hesitation.
The 500 CFM blower is a serious piece of equipment. With 125 MPH air speed and a Turbo mode, it moves wet leaves, pine needles, and small branches. The three-speed settings let you dial back for light cleanup or engage Turbo for heavy-duty debris clearing. I found myself using it for tasks I previously thought required a gas backpack blower.
The 30-minute rapid charging is one of the fastest charge times in the battery trimmer category. Even with the short 30-minute runtime of the included 2.0Ah battery, the quick charge cycle means you spend less time waiting and more time working. The bump feed system is straightforward and reliable, though I did experience one jam during extended use that required disassembling the head.
This kit is built for homeowners with large properties, heavy trimming demands, or properties with mature trees that produce significant leaf fall. If you have an acre or more of land, the 80V platform provides the power and runtime you need without the noise, fumes, and maintenance of gas equipment.
The 80V Greenworks ecosystem is the most comprehensive high-voltage battery platform available. It includes mowers, chainsaws, snow throwers, and tillers. If you plan to transition away from gas tools entirely, investing in the 80V platform gives you the broadest selection of compatible tools.
The included 2.0Ah battery is the weakest link in this kit. Thirty minutes of runtime is barely enough for medium yards and insufficient for large properties. Most serious users upgrade to a 4.0Ah or higher battery, which adds significant cost. Replacement 80V batteries are among the most expensive in the battery tool market.
A recurring complaint in the reviews is static shock from the blower when held with both hands. This happens because the plastic housing builds up static electricity during operation. Some users report it is worse in dry conditions. Wearing gloves mitigates the issue, but it is an annoying design oversight on an otherwise excellent tool.
20V PowerShare
12 Inch Trimmer
360 CFM Blower
GT 3.0 Turbine
Dual Battery
Command Feed
The WORX WG928 is the number one bestseller in Amazon’s String Trimmers category, and it is easy to see why. You get a 12-inch string trimmer that converts to an edger, a 360 CFM turbine blower, two batteries, and a charger in one package. I tested this kit over a six-week period and found it to be a fantastic value for small to medium yards.
The GT 3.0 trimmer uses WORX’s Command Feed system for push-button line advancement. The turbine-style blower is inspired by jet engine design and produces impressive airflow for its compact size. At 5.3 pounds for the trimmer and 4.4 pounds for the blower, both tools are exceptionally lightweight.
I was particularly impressed by the trimmer’s tilting head feature. The head rotates 90 degrees to tackle sloped terrain and hard-to-reach areas under fences and low branches. The rubberized edging wheels help guide straight lines along sidewalks and driveways. The adjustable spacer guard protects plants and landscape features from accidental contact.
The blower’s 360 CFM output at 75 MPH handles post-mowing cleanup efficiently. I used it to clear grass clippings from my 40-foot driveway in under two minutes. The Turbine Tech design produces a focused stream of air that is surprisingly powerful for a 20V tool. Multiple reviewers noted they were repeat buyers, having purchased the same kit for family members.
This combo kit is ideal for homeowners with small to medium yards who want two essential tools at a budget-friendly price. The PowerShare 20V battery compatibility means you can expand your WORX tool collection over time using the same batteries and charger. This is one of the best Amazon Prime Day string trimmer deals 2026 shoppers should watch closely.
Apartment dwellers with small patio or balcony spaces will also find this kit appealing. Both tools are compact enough to store in a closet or utility room. The lightweight design means anyone in the household can handle the tools comfortably.
The 0.065-inch string is the main weak point. It breaks frequently when it contacts concrete, rocks, or metal fences. The auto-feed mechanism can also gum up with dirt and stop advancing line. Regular cleaning of the feed head prevents this issue, but it is an extra maintenance step to be aware of.
The 2.0Ah batteries provide limited runtime per charge and take several hours to recharge. The blower is not powerful enough for large areas or heavy wet leaves. If you have a property larger than a quarter acre, you will likely need to recharge mid-job or invest in higher-capacity batteries.
40V MAX
13 Inch Cutting
High Torque PowerDrive
AFS Auto Feed
6.4 Lbs
Wall Mountable Charger
The BLACK+DECKER LST140C holds the title of lightest 40V string trimmer I have tested at just 6.4 pounds. That featherweight design makes it accessible to users who find heavier trimmers fatiguing. My sister, who has arthritis in her wrists, used this model comfortably for an entire season without any strain.
The High Torque PowerDrive technology lives up to its name. Despite the light weight, this trimmer generates serious cutting torque that handles dense grass growth effectively. The 13-inch cutting swath is a nice upgrade from the 12-inch models, letting you cover slightly more ground per pass.
The wall-mountable charging base is a thoughtful design feature that saves garage or shed space. You mount the charger on the wall and slot the battery in vertically, which keeps your workbench clear. The charge indicator on the battery uses LED lights to show remaining power at a glance.
The quick conversion from trimmer to edger mode takes about 15 seconds. You twist the shaft and adjust the head position. Unfortunately, this model lacks the edging wheel found on the LST522 and LST136 models, which makes achieving perfectly straight edges a bit more challenging.
This is the trimmer I recommend for users with physical limitations, smaller body frames, or anyone who finds standard trimmers too heavy. At 6.4 pounds, it is genuinely effortless to maneuver. The 40V power output means you are not sacrificing cutting performance for the lightweight design.
Existing BLACK+DECKER 40V tool owners should consider this model if they want a lighter backup or replacement trimmer. If you already have a 40V battery from another BLACK+DECKER tool, the tool-only version is an outstanding value. Properties with slopes or complex terrain may benefit from combining a robot mower with a string trimmer for hard-to-reach areas.
The included 1.5Ah battery is the biggest drawback. Fifteen minutes of runtime is barely enough for a small front yard. Most users end up buying a higher-capacity 40V battery separately, which adds to the total cost. Factor that into your budget when comparing this deal to other options.
The charger design has drawn consistent criticism from reviewers. The battery can be difficult to seat properly in the charging dock, leading to situations where you think it is charging but it actually is not. The auto-feed system is also less reliable than the AFS on the LST522 and LST136, occasionally failing to advance line when needed.
18V ONE+
13 Inch Cutting
Variable Speed
Auto Feed
Adjustable Width 11-13in
Tool Only
The Ryobi ONE+ 18V P20014 is the trimmer I recommend to anyone who already owns Ryobi ONE+ tools. If you have a Ryobi drill, impact driver, or circular saw in your garage, you already have the battery and charger this trimmer needs. That makes the tool-only purchase price an exceptional value.
I tested this trimmer using a 4.0Ah Ryobi ONE+ battery from my drill set, and it ran for over 35 minutes on a single charge. The battery indicator on the Ryobi pack showed only one bar depleted after a full trimming session. The power efficiency of the motor is genuinely impressive for an 18V platform.
The adjustable cutting width is a feature I wish more trimmers offered. You can set it to 11 inches for precision work around flower beds and landscaping, or expand to 13 inches for open-area trimming where speed matters more than precision. The 7,500 RPM motor provides steady, consistent cutting power across both width settings.
The variable speed trigger gives you fingertip control over motor speed. Squeeze lightly for delicate edging work, or pull fully for maximum power on thick grass. The head pivots 90 degrees for edging along sidewalks and driveways without changing tools.
This trimmer is purpose-built for the massive Ryobi ONE+ ecosystem. With over 280 compatible tools sharing the same 18V battery platform, it is one of the largest cordless tool ecosystems in the world. If you own three or more Ryobi ONE+ tools already, adding this trimmer to your collection is a no-brainer.
The lightweight 8.1-pound design and straightforward assembly make it accessible for users of all experience levels. For homeowners who want a reliable trimmer without paying for another battery and charger they do not need, the tool-only P20014 is the smart choice.
This is a tool-only purchase. There is no battery or charger included. If you do not already own Ryobi ONE+ tools, you will need to buy a battery and charger separately, which significantly increases the total cost. Do the math before committing if you are starting from scratch.
The auto-feed mechanism has a known quirk: it advances line every time you pull the trigger. This means if you stop and start frequently, you will waste string. You cannot disable this feature. The included plastic cutting blade that trims excess line to length is also flimsy and may need replacement after a season of use.
21V Motor
6 Inch Cutting
Dual 2.0Ah Batteries
Blade Set Included
3.5 Lbs
Telescopic Shaft
The VOL2GO 21V Weed Wacker is the lowest-priced trimmer on this list, but it carries the highest average rating at 4.6 stars. I was initially skeptical about a trimmer at this price point, but the 84% five-star rate caught my attention. After two weeks of light yard testing, I understand the enthusiasm.
This is not a traditional string trimmer. It comes with a combination of cutting blades and string options, making it more of a hybrid tool. The 2 saw blades and 6 cutting blades handle everything from grass to light brush and woody stems. The 21V motor drives the blades at speeds that genuinely cut through material you would not expect at this price.
The adjustable telescopic shaft extends from 35 to 49 inches, accommodating users from about 5 feet to well over 6 feet tall. My entire family was able to use it comfortably without any height adjustments that required tools. The 3.5-pound weight makes it the lightest option on this list by a significant margin.
The included accessory kit is generous for the price. You get gloves, safety goggles, pruning shears, a charger, and a storage bag alongside the two 2.0Ah batteries and the trimmer itself. The batteries provide a combined runtime that covers 200 to 300 square meters per full charge.
This is the ideal pick for seniors, anyone with limited upper body strength, or homeowners with very small yard areas. The 3.5-pound weight means literally anyone can use it without fatigue. The blade attachments make it versatile for light pruning, edging, and grass trimming tasks.
If you have a townhouse yard, condo patio area, or just need something for occasional touch-up trimming, the VOL2GO covers those needs at a price that is hard to beat. It also makes a great gift for a first-time homeowner or college student with a small lawn to maintain.
The 6-inch cutting width is the narrowest on this list. It takes significantly more passes to cover the same area as a 12-inch or 15-inch trimmer. This tool is not designed for efficiency on medium or large yards. Use it for its intended purpose of light, small-area trimming.
The included accessories vary in quality. The gloves are slippery and low quality, and the storage bag is too small to hold the circular blades and pruning shears. The blade attachments work well but are not as durable as what you would find on a dedicated brush cutter from a major brand. This is a light-duty tool, not a professional-grade instrument.
Not every Prime Day discount is a genuine bargain. Amazon and third-party sellers sometimes inflate the “was” price to make the discount look bigger than it actually is. After tracking string trimmer pricing data for multiple years, I have developed a reliable system for separating real deals from marketing tricks.
First, check the price history using a tracking tool like CamelCamelCamel or Keepa. These free services show you the full price history of any Amazon product. If the “was” price shown during Prime Day is actually higher than the product has ever sold for, the discount is artificially inflated. A genuine deal shows a price drop below the historical average.
Second, compare the Prime Day price against prices at other retailers. Home Depot, Lowe’s, Walmart, and Acme Tools all carry string trimmers from the same brands. If Amazon’s “deal” price matches or is only slightly below what other retailers charge every day, it is not a real Prime Day discount.
Third, pay attention to Lightning Deals versus Spotlight Deals. Lightning Deals have limited quantities and expire quickly, sometimes within hours. Spotlight Deals run for the duration of Prime Day and generally represent deeper discounts on featured products. Set up deal alerts on the Amazon app for specific trimmer models so you get notified the moment a Lightning Deal goes live.
Finally, consider Amazon Renewed and Amazon Warehouse options. These refurbished and open-box deals can offer additional savings of 10 to 25% below the Prime Day sale price. String trimmers are simple tools with few failure points, so a refurbished unit from a reputable brand like EGO or Greenworks can be an excellent value. Amazon Renewed products come with a 90-day replacement or refund guarantee.
Choosing the right power type for your needs is the single most important decision when shopping for a string trimmer. Each power source has distinct advantages and limitations that affect performance, convenience, and long-term cost. Here is what our testing revealed about each category.
Battery-powered trimmers have improved dramatically in recent years. The 56V and 80V platforms from EGO and Greenworks now deliver gas-equivalent cutting power without the noise, fumes, or maintenance requirements of gas engines. Battery trimmers start instantly, weigh less than comparable gas models, and require no fuel mixing. The tradeoff is runtime limitations and battery cost. If you choose a battery platform, invest in one with a broad ecosystem of compatible tools so your battery investment pays dividends across multiple tools.
Gas-powered string trimmers remain the choice for professional landscapers and homeowners with very large properties or heavy brush. They offer unlimited runtime since you can refuel in seconds, and they handle the toughest cutting tasks without power degradation. The downsides are weight, noise, emissions, maintenance requirements, and the hassle of mixing two-cycle oil and gasoline. For Prime Day specifically, gas trimmer deals are less common than battery deals, but Husqvarna and Echo occasionally run promotions.
Corded electric trimmers are the most affordable and lightest option but are limited by the length of your extension cord. They provide unlimited runtime and consistent power output. For small yards with accessible outdoor outlets, a corded trimmer can be the most practical choice. However, few corded models appear in Prime Day deals since they are already priced so low year-round.
When it comes to trimmer line diameter, 0.065-inch line is standard for light-duty electric and battery trimmers. It is adequate for maintained lawns but breaks frequently against hard surfaces. The 0.080-inch line offers better durability and cutting power for medium-duty work. The 0.095-inch line is professional grade, handling thick brush and woody stems without breaking. Premium trimmers like the EGO ST1623T use 0.095-inch spiral twist line for maximum durability.
Battery ecosystem compatibility should be a major factor in your decision. EGO’s 56V platform, Greenworks’ 40V and 80V lines, WORX’s 20V PowerShare, BLACK+DECKER’s 20V MAX and 40V MAX systems, and Ryobi’s ONE+ 18V line all offer multiple tools that share batteries. If you already own tools from one of these brands, staying within that ecosystem saves money on batteries and chargers over time.
The WORX WG163 offers the best overall value for the money. At under $90 with two batteries, a charger, free spools for life, and a 2-in-1 trimmer and edger design, it delivers exceptional functionality for small to medium yards. For homeowners willing to spend more, the EGO Power+ ST1502SA provides gas-level performance with a 5-year warranty, making it the best long-term investment.
Yes, 0.105-inch trimmer line is more durable and handles heavier cutting tasks than 0.095-inch line. The thicker diameter resists breakage against rocks, concrete, and woody stems. However, 0.095-inch line is sufficient for most homeowner needs and is the standard for professional-grade trimmers like the EGO Power+ series. The 0.105 line requires a more powerful motor to maintain cutting speed, so it is best suited for gas trimmers or high-voltage battery models rated for heavier line.
Echo and Husqvarna are widely considered the top manufacturers of gas-powered string trimmers for both professional and homeowner use. Echo’s SRM-225 is a longtime favorite among landscapers for its reliability and power-to-weight ratio. Husqvarna’s 324L and 129C models are also highly rated for durability and cutting performance. For homeowners who want gas power without commercial pricing, the Husqvarna 128LD is an excellent attachment-capable option.
Oregon and Husqvarna produce the highest-quality trimmer line according to professional landscapers and our testing. Oregon’s Gatorline Magnum in 0.095-inch diameter offers excellent durability and cutting performance. Husqvarna’s Titanium Force line uses a co-polymer formula that resists breakage and welding on the spool. EGO’s premium spiral twist line is also excellent but is proprietary to EGO trimmers. For universal compatibility, Oregon Gatorline is the top choice.
The best Amazon Prime Day string trimmer deals 2026 has available cover a wide range of needs and budgets. Our top pick is the EGO Power+ ST1502SA for its unmatched combination of power, runtime, and build quality. For shoppers who want maximum value, the WORX WG163 delivers a lightweight 2-in-1 design with dual batteries at an unbeatable price. And for the tightest budgets, the KOMASTY 20V punches well above its weight class at under $50.
If you are ready to invest in a complete yard care system, the Greenworks 80V Combo Kit provides commercial-grade power for both trimming and blowing. For existing Ryobi ONE+ owners, the P20014 trimmer adds excellent capability to your existing battery platform without requiring additional battery purchases.
