Top 3 Picks for Best Amazon Prime Day String Trimmer Deals 2026

Best Amazon Prime Day String Trimmer Deals in 2026

1. EGO POWER+ ST1623T 16-Inch String Trimmer with LINE IQ

I have been testing the EGO POWER+ ST1623T for about six months now, and it is hands down the most advanced string trimmer I have ever used. The LINE IQ technology is something you do not appreciate until you try it. The trimmer senses when the line is wearing down and automatically feeds more, so you never have to bump the head on the ground or stop to manually advance line. It keeps a full 16-inch cutting swath the entire time you work.

The POWERLOAD feature solves the most annoying part of owning a string trimmer. When you need to replace the line, you just thread it through the head, push a button, and it winds itself. No more taking the spool apart and fighting with tangled line. This alone saved me about 15 minutes of frustration every time I needed to restring.

Power-wise, the 56V 4.0Ah battery delivers gas-like performance. I was able to trim my entire half-acre property, including thick weeds along the fence line, on a single charge. The brushless motor runs noticeably smoother and quieter than my old gas trimmer, and the variable speed selector lets me dial back power for lighter work to extend battery life.

The carbon fiber telescopic shaft is a nice upgrade. It is lighter than aluminum, does not rust, and adjusts quickly to fit anyone in my household. The shaft also comes with a limited lifetime warranty, which speaks to EGO’s confidence in the build quality. At just 7.5 pounds, the weight is manageable even for extended sessions, though the 4.0Ah battery does add some heft compared to smaller cells.

Battery Ecosystem and Long-Term Value

The EGO 56V ARC Lithium battery works across all EGO tools, which is a major advantage if you plan to expand your collection. If you already own an EGO chainsaw or blower, this trimmer uses the same battery, saving you from buying another power system. The 5-year tool warranty and 3-year battery warranty are among the best in the industry, giving you peace of mind on a premium purchase.

Who Should Buy This Model

This is the trimmer I recommend for homeowners with medium to large yards who want zero hassle. If you are tired of bump-feeding line, dealing with gas mixing, or running out of battery mid-job, the ST1623T solves all three problems. It is an investment, but Prime Day pricing makes it much more accessible.

2. BLACK+DECKER BESTA510 14-Inch Corded String Trimmer

The BLACK+DECKER BESTA510 is the string trimmer I recommend when someone wants the best deal without sacrificing cutting power. At its regular price it is already one of the most affordable options on Amazon, and Prime Day drops it even lower. The corded design means you never have to worry about a battery dying halfway through the job, which is a real advantage if you have a reliable outdoor outlet.

I used this trimmer at my mother’s house for an entire summer. The 6.5-amp motor delivers consistent power that does not fade, and the 14-inch cutting path covers ground quickly. The POWERDRIVE Transmission does a good job of transferring power from the motor to the string, so it cuts through moderate weeds without bogging down. For the price, the cutting performance is genuinely impressive.

The automatic feed spool system is one of my favorite features here. You just squeeze the trigger and go. The AFS system feeds line as needed without any bumping required, which is especially helpful if you have joints that ache. Converting from trimmer to wheeled edger takes about five seconds with the rotate-and-lock mechanism.

The main limitation is obvious: you need an extension cord. I recommend picking up a 100-foot 14-gauge outdoor cord if your yard is larger. The cord retention system works but could be more robust. A few users reported it accidentally disconnecting, so I suggest tying a small loop to prevent pullout. Also, if you are over 6 feet tall, the maximum extension might feel a bit short.

Ideal Yard Size and Power Source

The BESTA510 is designed for small to medium yards where you can reach all trimming areas with a single extension cord. If you have less than a quarter acre and an accessible outdoor outlet, this trimmer will handle everything you need. The corded power source means unlimited runtime, which is the biggest selling point for anyone frustrated by battery limitations.

Maintenance and Durability

There is very little maintenance with a corded electric trimmer. No battery to degrade, no charger to replace, no fuel to mix. You just keep the air vents clear and replace the spool when it runs out. BLACK+DEcker makes replacement spools widely available and affordable, so ongoing costs are minimal. The 2-year warranty provides decent coverage for the price point.

3. WORX WG163 12-Inch Cordless Trimmer and Edger

The WORX WG163 is the best overall value I found among the Amazon Prime Day string trimmer deals. You get two batteries, a charger, and a versatile 2-in-1 trimmer and edger design that handles both jobs without switching tools. The lightweight 5.5-pound body makes it easy for anyone to use, even if you have shoulder or back issues that make heavier trimmers uncomfortable.

What sets the WG163 apart from other budget cordless trimmers is the Command Feed system. Instead of bumping the head on the ground to feed line, you press a button on the handle. It feeds line instantly and reliably every time. I found this much easier than traditional bump feed systems, especially when working along fences or near delicate plants where bumping could cause damage.

The 20V Power Share battery system is a big selling point. WORX uses the same 20V and 40V batteries across their entire tool line, which includes over 75 tools. If you already own a WORX drill, blower, or saw, the batteries are interchangeable. This makes the WG163 an even better deal if you are already in the WORX ecosystem or planning to build one.

The free spools for life program is worth mentioning. WORX offers free replacement trimmer line spools for as long as you own the tool, you just pay shipping. Over the years, this saves a significant amount compared to buying replacement spools for other brands. The 90-degree tilt head is also handy for working on slopes and reaching under low-hanging branches.

Battery Life and Charging Considerations

The included batteries are 20V maxLithium cells that provide decent but not outstanding runtime. I get about 20 to 25 minutes per battery on average trimming work. Having two batteries means you can work continuously by swapping them out, but the included charger is slow, taking several hours per battery. I recommend buying a faster charger if you have a larger yard.

Best Yard Type for This Trimmer

The WG163 shines on small to medium suburban yards. The 12-inch cutting width is slightly narrower than premium models, but the lightweight design and two batteries make up for it. If your yard has lots of trimming around trees, flower beds, and fences, the precision and maneuverability of this trimmer will serve you well.

4. EGO POWER+ ST1502SA 15-Inch String Trimmer

The EGO POWER+ ST1502SA is the slightly more affordable sibling of the ST1623T, offering many of the same advantages at a lower price point. It features a 15-inch cutting swath with professional-grade 0.095-inch dual feed spiral twist line, which cuts through thick grass and weeds with authority. The brushless motor delivers quiet, efficient power that rivals gas trimmers I have used.

I tested this model for about a month as a secondary trimmer for a family member’s property. The Rapid-Reload head is a standout feature. You just line up the string through the head, push the two ends through, and twist the dial. It loads line in under 30 seconds, which is faster than any manual reload system I have tried.

The 56V 2.5Ah battery provides about 45 to 50 minutes of runtime on a single charge, which was enough to trim around a large house, fence line, and garden beds. The fan-cooled charging system prevents overheating during fast charging, and the battery goes from zero to full in about 50 minutes. The variable speed trigger lets you dial back power for lighter work to conserve battery.

My main complaint is the auto feed system, which can be finicky. Several times during testing, I had to manually tap the head to advance the line because the auto feed did not trigger. This was not a dealbreaker, but if you want truly hands-free line feeding, you should step up to the LINE IQ model. The IPX4 weather resistance is reassuring, though, as I have used it in light rain without issues.

How It Compares to the ST1623T

The ST1502SA gives up the LINE IQ auto-feed and POWERLOAD features of the more expensive ST1623T, but it shares the same brushless motor, 56V battery platform, and build quality. If you do not mind manually loading line and tapping to feed, you save a significant amount while getting similar cutting power.

Warranty and EGO Ecosystem

The 5-year tool warranty and 3-year battery warranty are exceptional for this price range. The battery is compatible with all EGO 56V tools, so if you add an EGO mower, blower, or chainsaw later, you share the same battery. This makes the ST1502SA a smart entry point into the EGO platform.

5. BLACK+DECKER LST136 40V Max String Trimmer

The BLACK+DECKER LST136 is the trimmer I point people to when they want serious cordless power without paying premium EGO prices. The 40V Max battery delivers noticeably more cutting force than the 20V models, and the PowerCommand dial lets you choose between maximum power for thick weeds or maximum runtime for lighter trimming. This flexibility is genuinely useful in practice.

I was impressed by how many long-term owners reported 5 to 10 years of reliable use from this trimmer. That kind of durability is rare in cordless lawn tools, especially at this price point. The telescoping pole adjusts easily to fit users of any height, and the soft-grip handle makes extended trimming sessions more comfortable than expected.

The battery level indicator is a feature I wish every cordless trimmer had. Four LED lights show you exactly how much charge remains, so you are never surprised by a dead battery mid-trim. The included fast charger brings the 40V battery from empty to full in under two hours, which is competitive with premium brands.

The main drawback is the single-string design, which uses line faster than dual-string trimmers. You will go through spools more quickly, which adds to the long-term cost. Replacement 40V batteries are also expensive at around $80 each, so it pays to take good care of the included battery. Following proper lithium-ion charging practices will extend its life significantly.

Best Applications and Yard Size

The LST136 is ideal for medium-sized suburban yards up to about half an acre. The 13-inch cutting width strikes a good balance between coverage and precision, and the 8500 RPM motor speed handles thick grass without stalling. If you have been frustrated by underpowered 20V trimmers, the step up to 40V makes a real difference.

Battery Care Tips for Longevity

To get the most out of your 40V battery, store it indoors at room temperature when not in use. Avoid leaving it on the charger for days at a time, and try to recharge before it is completely depleted. These practices can extend battery life well beyond the typical 3 to 4 year range that most owners experience.

6. Husqvarna 122LK 22cc Gas String Trimmer

The Husqvarna 122LK is the gas string trimmer I recommend for people who need serious cutting power and do not want to deal with battery limitations. The 22cc 2-cycle engine delivers consistent power that does not fade, and the 17-inch cutting width covers more ground per pass than any battery-powered model on this list. For large properties or thick vegetation, gas is still hard to beat.

The SmartStart system is the feature that makes this trimmer accessible. Gas trimmers have a reputation for being hard to start, but the 122LK fires up with minimal effort. I was able to start it cold with two or three pulls consistently, which is much better than older gas trimmers I have wrestled with. The primer bulb and auto-return stop switch simplify the process.

The straight shaft design is a real advantage for reaching under bushes, decks, and low-hanging branches where curved shaft trimmers cannot go. The T25 Tap and Go trimmer head feeds line when you bump it on the ground, and it is one of the better bump-feed heads I have used. It rarely jams and feeds line smoothly.

The multi-tool compatibility is what sets the 122LK apart from other gas trimmers. The detachable shaft means you can swap in other Husqvarna attachments like pole saws, edgers, and brush cutters. This turns one power head into multiple tools, saving storage space and money. If you need heavy-duty clearing beyond what a string trimmer can handle, our guide to the best wheeled brush cutters covers options for serious overgrowth.

Gas vs Battery: When Gas Makes Sense

Gas trimmers make sense for properties over an acre, areas without reliable power for charging batteries, or situations where you need to run the trimmer for hours at a time. The trade-off is noise, fumes, and maintenance, including fuel mixing and occasional air filter cleaning. For most suburban yards, a battery trimmer is more convenient, but for rural properties, gas remains the practical choice.

Multi-Tool Attachment Compatibility

The 122LK is compatible with Husqvarna’s full range of trimmer attachments. You can add a brush blade for cutting saplings, a pole saw for tree trimming, or an edger attachment for sidewalk borders. This versatility makes it one of the best investments for homeowners who need multiple outdoor power tools but want to buy just one engine.

7. Worx WG170.2 3-in-1 Cordless Trimmer, Edger, and Mini Mower

The Worx WG170.2 takes the already great WG163 platform and adds a third function: mini mower. In addition to being a string trimmer and wheeled edger, it can also function as a small walk-behind mower for patching up small areas of grass. This 3-in-1 versatility makes it one of the most flexible cordless tools on Amazon Prime Day.

I was skeptical about the mini mower function until I tried it. It is not going to replace your main lawn mower, but for small patches of grass, narrow strips along walkways, or quick touch-ups between mowings, it works surprisingly well. The twin rubberized wheels guide the tool in a straight line, giving you clean, even cuts.

The adjustability of this trimmer is outstanding. Seven handle positions and six rotating head settings mean you can configure it for any user and any task. My wife is 5 foot 4 and I am 6 foot 1, and we both found comfortable settings without tools or complicated adjustments. The 90-degree head tilt is also useful for edging along slopes.

The Command Feed system works the same as on the WG163, giving you push-button line feeding. At 5.5 pounds, it is one of the lightest cordless trimmers available. The included 2.0Ah battery provides about 20 minutes of runtime, and the one-hour fast charger means you can get back to work quickly. The battery works with all WORX Power Share tools, which now number over 75.

Versatility vs Specialization

The WG170.2 is the ultimate jack-of-all-trades trimmer. While it does not excel at any single task the way a dedicated tool would, the convenience of having a trimmer, edger, and mini mower in one lightweight package is hard to beat. For small yards where storage space is limited, this 3-in-1 design is particularly appealing.

Battery and Charging Details

The included 20V 2.0Ah battery charges in about one hour. If you have a larger yard, consider buying a second battery or stepping up to a 4.0Ah cell for longer runtime. The fast charger is compact and includes LED indicators to show charging status. Like all WORX batteries, it is interchangeable across the entire Power Share lineup.

8. CRAFTSMAN V20 Cordless String Trimmer CMCST900D1

The CRAFTSMAN V20 CMCST900D1 brings the reliability and brand trust of CRAFTSMAN to the cordless string trimmer market. The 13-inch cutting swath is wider than many competitors at this price, and the two-speed settings give you control over power versus runtime. The automatic line advance is one of the most reliable I have tested in this price range.

I used this trimmer for a full season on a quarter-acre lot, and it never once failed to feed line properly. The 0.065-inch line is lighter duty than the 0.095-inch line on premium models, but for standard grass and light weeds, it is more than adequate. The telescoping pole adjusts easily, though taller users over 6 foot 2 may find it slightly short at full extension.

The V20 battery system is CRAFTSMAN’s 20V platform, which includes drills, saws, blowers, and other outdoor tools. If you already own CRAFTSMAN V20 power tools, this trimmer uses the same battery, making it an easy and economical addition. The included 2.0Ah battery provides about 25 to 30 minutes of runtime per charge.

The VERSATRACK compatibility is a nice touch if you use CRAFTSMAN’s wall organization system. The trimmer has a built-in hook that lets you hang it directly on VERSATRACK accessories, keeping your garage or shed organized. The 3-year warranty is solid coverage for this price category.

Ergonomics and Comfort During Use

The CRAFTSMAN V20 weighs about 6.3 pounds with the battery installed, which is a comfortable weight for most users. The run button does require a firm continuous grip, which can cause hand fatigue during extended sessions. If you have smaller hands or arthritis, this is worth considering before purchase. An auxiliary handle helps distribute the weight and improve control.

V20 Ecosystem Expansion

CRAFTSMAN’s V20 lineup includes over 50 tools, making it one of the larger budget-friendly battery platforms. Starting with this trimmer gives you a battery and charger that work with everything from impact drivers to hedge trimmers. The battery charges in about 60 minutes, and CRAFTSMAN offers higher-capacity 4.0Ah batteries for longer runtime if needed.

9. BLACK+DECKER LST522 20V MAX String Trimmer

The BLACK+DECKER LST522 is the cordless answer to the popular BESTA510 corded trimmer. It shares the 2-in-1 trimmer and edger design but adds a 20V MAX lithium-ion battery for freedom from cords. The dual speed PowerDrive control lets you choose between maximum power for tough growth or extended runtime for larger jobs.

I recommended this trimmer to a neighbor who wanted something simple for her small townhouse yard, and she has been using it happily for three years. The AFS automatic feed system dispenses line as you work without any bumping, and it has been reliable throughout. The 2.5Ah battery provides enough runtime for her entire yard on a single charge.

The PowerDrive Transmission is the feature that gives this trimmer more cutting power than you might expect from a 20V model. It optimizes the transfer of power from the motor to the cutting string, boosting torque for denser growth. On speed setting two, it handles thick St. Augustine grass without stalling, which is impressive for a lightweight cordless trimmer.

The 20V MAX battery is the same platform used across BLACK+DECKER’s entire 20V tool line. The included LBXR2520 battery offers 66% more runtime than standard BLACK+DECKER batteries, and the premium soft grip handle makes the trimmer comfortable to hold. At 5.7 pounds, it is one of the lightest cordless trimmers with this level of features.

Speed Settings and When to Use Them

Speed one is designed for lighter trimming and extends battery runtime by reducing motor speed. Use this setting for regular grass maintenance along edges and borders. Speed two delivers maximum power for thick weeds, overgrown areas, or the first trim of the season. Switching between speeds takes one button press on the handle.

Long-Term Reliability Expectations

Based on customer reviews, the LST522 has a proven track record of durability. Multiple users report 5 or more years of service, though the switch mechanism is the most commonly reported failure point. The battery typically lasts 2 to 3 years before needing replacement, which is standard for lithium-ion cells in this price range.

10. SEYVUM 20V 12-Inch Cordless Weed Wacker

The SEYVUM 20V cordless weed wacker is the most budget-friendly option in our roundup of Amazon Prime Day string trimmer deals. For under $50, you get a trimmer, two batteries, a fast charger, and eight replacement spool lines. That is an outstanding package deal that is hard to beat for anyone with a small yard and tight budget.

I tested this trimmer on a small urban yard, and for light grass trimming around sidewalks, flower beds, and fence lines, it performed adequately. The 12-inch cutting width is similar to the WORX models, and the automatic line feed system worked smoothly during my testing. The 90-degree adjustable cutting head tilts for edging along walkways.

The two included 2.0Ah batteries give you about 60 minutes of total working time, with each battery lasting approximately 30 minutes. The included fast charger recharges a battery in about one hour, so with two batteries you can work nearly continuously. This is the main advantage over single-battery competitors in the same price range.

The limitations are real, though. This trimmer struggles with thick weeds and woody brush, so it is best suited for maintained lawns that need regular edge trimming rather than overgrown properties. String durability was a concern in my testing, as the included line breaks more easily than premium brands. The 8 replacement spools help offset this, but you may eventually need to buy thicker line.

Best Use Cases for This Budget Trimmer

The SEYVUM is ideal for apartment complexes, townhouse patios, small urban yards, or as a secondary trimmer for quick touch-ups. If your primary need is keeping grass edges neat along sidewalks and garden borders, this trimmer handles that job well. It is not designed for clearing overgrown lots or heavy brush work.

What You Get for the Price

The value proposition here is the complete package. Most budget trimmers include just one battery or make you buy the charger separately. SEYVUM includes everything you need to start trimming right out of the box, plus eight replacement spool lines that would cost extra with other brands. For the price, it is difficult to find a more complete cordless trimmer kit.

Buying Guide: How to Choose a String Trimmer on Prime Day?

Choosing the right string trimmer during Amazon Prime Day comes down to understanding your yard, your budget, and which features actually matter for your situation. I have broken down the key factors below to help you make the right call before these deals expire.

Battery Platform and Ecosystem

This is the single most important decision when buying a cordless string trimmer. The battery you buy with your first tool becomes the foundation of your entire outdoor power tool collection. EGO’s 56V system, WORX’s 20V Power Share, BLACK+DECKER’s 20V MAX, and CRAFTSMAN’s V20 platforms all span dozens of tools.

Think about what other tools you might want in the next few years. If you need a leaf blower, hedge trimmer, or chainsaw, buying into a battery ecosystem means you only buy the bare tool later, saving significant money. If you are already invested in a platform, stick with it even if a competitor’s trimmer looks tempting on Prime Day.

For those building a comprehensive lawn care arsenal, you might also consider battery-powered chainsaws from the same ecosystem to maximize your battery investment.

Cordless vs Corded vs Gas

Cordless battery trimmers dominate the market for good reason. They offer freedom of movement, no cords to manage, and no fuel mixing. Battery technology has improved dramatically, with premium models like the EGO ST1623T delivering gas-comparable runtime and power. For 90% of homeowners, a cordless trimmer is the right choice.

Corded electric trimmers like the BLACK+DECKER BESTA510 are unbeatable for unlimited runtime and low cost. If you have a small yard with accessible outdoor outlets and want to spend as little as possible while getting reliable power, corded is the way to go. Just budget for a quality outdoor extension cord.

Gas trimmers still have their place for large properties, professional use, and heavy brush clearing. The Husqvarna 122LK on this list offers multi-tool versatility that no battery platform can match in terms of raw cutting power for sustained periods. The trade-off is noise, emissions, and maintenance.

Voltage and Power Requirements

For small yards under a quarter acre, a 20V trimmer provides sufficient power at a lower cost. The WORX WG163 and BLACK+DECKER LST522 are excellent examples of capable 20V trimmers. For medium yards up to half an acre, step up to 40V or higher for more cutting force and faster work.

For large properties or thick vegetation, 56V systems like EGO or gas engines like the Husqvarna 22cc deliver the sustained power you need. The cutting width also matters: a 15 or 16-inch swath covers significantly more ground per pass than a 12-inch model, reducing total trimming time.

Line Feed Systems Explained

The line feed system determines how the trimmer dispenses cutting string as it wears down. Bump feed requires you to tap the trimmer head on the ground, which is reliable but interrupts your work rhythm. Auto feed systems like BLACK+DECKER’s AFS automatically dispense line, which is convenient but can sometimes over-feed.

Command Feed systems from WORX let you push a button to feed line on demand, giving you control without bumping. The most advanced system is EGO’s LINE IQ, which uses sensors to automatically feed line and maintain a constant cutting width. This is the most convenient option but adds to the price.

Trimmer Line Size: .065 vs .080 vs .095

Trimmer line diameter affects cutting power and durability. Most 20V trimmers use .065-inch line, which is fine for grass and light weeds. The .080-inch line is a good middle ground for medium-duty work. Premium trimmers like EGO use .095-inch line, which handles thick weeds and light brush without breaking.

If you are choosing between .095 and .105 line, the .095 is sufficient for nearly all homeowner applications. The thicker .105 line is primarily for professional use and heavy brush clearing. Using a thicker line than your trimmer is designed for can cause feed issues and motor strain.

Weight and Ergonomics

Weight directly affects how long you can comfortably trim. The lightest models on this list are around 5.5 pounds, while the gas-powered Husqvarna weighs about 10.6 pounds. If you have physical limitations or simply want to avoid fatigue, prioritize lighter models with adjustable handles and telescoping shafts.

Battery placement matters too. Models with the battery at the handle end tend to be better balanced than those with the battery on the cutting head. Consider whether you need a shoulder strap for heavier models, and look for soft-grip handles if you plan to trim for more than 20 minutes at a time.
