12 Best Prime Day String Trimmer Deals (July 2026) Expert Guide

Amazon Prime Day 2026 is here, and if you have been waiting to score a deal on a string trimmer, this is your moment. Our team spent the last three weeks testing 12 of the most popular weed whackers available on Amazon, ranging from budget corded models under $60 to professional-grade gas trimmers pushing $450. We wanted to separate the real deals from the marketing fluff so you do not waste your money during the biggest sale event of the year.

Finding the best Amazon Prime Day string trimmer deals means looking beyond the discount percentage. A trimmer that drops 30 percent but cannot handle your half-acre yard is not a deal at any price. We focused on real-world factors like battery runtime, cutting power, line feed reliability, and weight during extended use. Every product on this list has been put through actual lawn work, not just spec-sheet comparisons.

Whether you need a lightweight cordless trimmer for a small suburban lawn, a combo kit with a blower included, or a heavy-duty gas machine for brush clearing, we have a pick that fits. Prime Day deals sell out fast, so we organized everything by category to help you move quickly. Let us get into the top picks and full reviews so you can grab the best deal before inventory disappears.

Top 3 Picks for Amazon Prime Day String Trimmer Deals

These three picks represent the sweet spots across the string trimmer market. The EGO ST1610T takes our editor’s choice spot for its POWERLOAD technology and carbon fiber shaft that makes line changes almost effortless. The CRAFTSMAN CMCST901M1 offers the best balance of price, runtime, and power with 63 minutes of cutting time on a single charge. And the WORX WG119 keeps things under $60 with corded reliability and a 2-in-1 edger design.

Best Amazon Prime Day String Trimmer Deals in 2026

1. EGO POWER+ ST1610T 16-inch with POWERLOAD – Premium Cordless Performance

I have used a lot of string trimmers over the years, and the EGO ST1610T genuinely surprised me with its POWERLOAD technology. You thread the line through the head, press a button, and the trimmer winds it automatically. No more taking the head apart, no more fighting with tangled spools. It is the kind of feature that sounds like a gimmick until you use it and realize you never want to go back.

The carbon fiber shaft keeps the weight down to just 7.5 pounds without the battery, which is lighter than most competing 16-inch trimmers. The telescopic shaft adjusts easily, and the auxiliary handle gives you solid control when trimming around obstacles. In testing, the brushless motor powered through thick weeds and tall grass without bogging down, and the 0.095-inch dual spiral-twist line held up well against fence posts and rocks.

The 16-inch cutting swath is generous for a battery trimmer. I covered my entire quarter-acre property in under 25 minutes with battery to spare. The IPX4 weather resistance rating means you can trim after a rain without worrying about moisture damage, which is something not every battery trimmer offers.

One important note: this trimmer ships without a battery or charger. If you already own EGO 56V tools, this is a non-issue and actually saves you money. If you are new to the EGO ecosystem, factor in the cost of a battery and charger when evaluating the deal price.

For Whom It Is Good

This trimmer is ideal for homeowners with medium to large properties who want premium cordless performance without gas fumes. If you already own EGO 56V batteries from a mower or blower, this is an easy addition that maximizes your existing investment. The POWERLOAD feature alone makes it worth the upgrade if you hate manual line winding.

For Whom It Is Bad

If you are starting from scratch and need a battery and charger, the total cost pushes past the $250 range even on sale. Buyers with tiny lawns who only need light trimming will find this trimmer more powerful than necessary. And if you prefer gas power for heavy brush clearing, even the best battery trimmer has runtime limitations.

2. CRAFTSMAN V20 CMCST901M1 – Best Battery Runtime for the Price

The CRAFTSMAN CMCST901M1 earned the highest rating in our entire test batch at 4.6 stars, and the reason is simple: it ships with a 4Ah battery and delivers up to 63 minutes of runtime on a single charge. That is nearly double what most trimmers in this price range offer. For anyone tired of battery trimmers dying mid-yard, this model solves that problem.

I tested this trimmer on a property with a mix of lawn grass and some stubborn weeds along the fence line. The 13-inch cutting path is narrower than the EGO, but the trade-off is better precision around flower beds and landscaping features. The Turn-to-Edge feature lets you rotate the head 90 degrees for vertical edging along driveways and walkways without switching tools.

The two speed settings give you control over power versus runtime. On low speed, I got the full 63 minutes easily. On high speed, power increased noticeably for thicker patches, but runtime dropped to around 40 minutes. The brushless motor delivers what CRAFTSMAN claims is 52 percent more power than their standard V20 trimmers, and based on cutting performance, I believe it.

The included 4Ah battery is the standout feature here. Many trimmers at this price include a 2Ah battery that lasts 20 to 30 minutes. Getting a 4Ah pack means you can trim an entire average-sized yard without stopping. It also works with any other CRAFTSMAN V20 tools you already own, from drills to circular saws.

The adjustable handle and lightweight design make this comfortable for extended sessions. The balance is slightly different from older CRAFTSMAN models because of the new battery placement, but it took me about ten minutes to get used to the feel.

Battery Ecosystem Compatibility

If you already own CRAFTSMAN V20 tools, this trimmer is a no-brainer. The 4Ah battery alone is worth a significant portion of the price. Even if this is your first V20 tool, you are buying into one of the most affordable and widely available battery platforms on the market. Replacement batteries and chargers are easy to find and reasonably priced compared to proprietary systems like EGO or Echo.

Limitations for Heavy Use

This trimmer is not designed for clearing heavy brush or very tall, thick grass. The 0.065-inch line is lighter duty than the 0.095-inch line on premium models. If your property has areas with woody weeds or dense overgrowth, you will want to pair this with a gas trimmer or step up to a higher-voltage battery system.

3. WORX WG119 Corded Electric – Best Budget String Trimmer Deal

At under $60, the WORX WG119 is the cheapest trimmer in our roundup, and for a corded electric model, it delivers solid value. I tested it on a small front yard with an extension cord, and the 5.5-amp motor spun the dual-line head at 7500 RPM without issue. It cut through standard lawn grass cleanly and handled light weeds along the edge of a garden bed.

The 2-in-1 design is the real selling point here. You rotate the shaft to convert from a trimmer to an edger in seconds. The 90-degree pivoting head also lets you reach under low bushes and around obstacles that a fixed-head trimmer cannot access. For a budget tool, WORX packed in a lot of versatility.

The auto line feed system worked reasonably well during testing, though it occasionally fed more line than needed. The telescopic shaft adjusted easily for my height, and at just 6 pounds, this trimmer is easy to handle for users of any strength level. The flower guard attachment helps protect plants while trimming close to landscaping.

The main limitation is the cord. If you have a large property or areas far from an outlet, a corded trimmer becomes frustrating quickly. The cord can also get snagged on shrubs and obstacles. However, if your trimming area is near your house or garage, the unlimited runtime of a corded model is actually an advantage over battery trimmers.

Best Use Case for This Trimmer

This trimmer is perfect for small yards, townhomes, and anyone who only needs to trim along a driveway, sidewalk, or small fence line. The corded design means you never deal with dead batteries or charging wait times. It is also a great backup trimmer to keep in the garage for quick touch-ups.

Durability Considerations

Several long-term users reported motor issues when the trimmer is used in very dusty conditions, so avoid using it on dry dirt or gravel areas. The plastic guard can also come loose over time. For the price, these are acceptable trade-offs, but set your expectations accordingly for long-term durability.

4. WORX WG163 Cordless 20V with Command Feed – Best Lightweight Cordless

The WORX WG163 is the number one bestseller in Amazon’s string trimmer category, and after testing it, I understand why. WORX includes two batteries and a charger in the box, which means you can always have one charging while you work. At 5.5 pounds, it is one of the lightest cordless trimmers on the market, making it ideal for anyone who struggles with heavier tools.

The Command Feed system is a push-button line advancement that replaces traditional bump-feed heads. Instead of tapping the head on the ground to release more line, you press a button on the handle. In testing, this worked reliably and eliminated the frustration of line that would not feed or would feed too much.

The 12-inch cutting diameter is smaller than premium models, but for small to medium yards, it is more than adequate. The 7600 RPM motor speed provides clean cuts through grass and light weeds. The 2-in-1 design with a tilting head and rubberized edger wheels lets you create clean edges along sidewalks and driveways.

The PowerShare battery system is a major advantage. The 20V batteries work across the entire WORX PowerShare tool line, including their drills, saws, and blowers. If you already own WORX tools, this trimmer integrates seamlessly into your existing setup at no additional battery cost.

Battery Life Reality Check

Each battery provides roughly 20 to 25 minutes of runtime, so having two batteries gives you about 45 minutes total. That is enough for most suburban yards, but the included charger is slow, taking several hours per battery. Consider buying a fast charger separately if you need quicker turnaround between sessions.

Who Should Buy This Over Premium Options

If your yard is under a quarter acre and you want a lightweight, affordable cordless trimmer with no learning curve, this is the one. The two-battery setup and PowerShare ecosystem give it lasting value that budget one-battery trimmers cannot match.

5. BLACK+DECKER LST522 20V MAX – Best for Comfort and Ease of Use

BLACK+DECKER’s LST522 earned a 4.5-star rating from over 6,300 reviewers, and it stands out for pure user comfort. The soft grip handle, adjustable height, and 5.7-pound weight make this one of the most comfortable trimmers I tested. The AFS automatic line advancement system feeds line based on RPM, so you never have to bump or press anything.

The 2-speed PowerDrive transmission lets you choose between maximum power and maximum runtime. On low speed, I got about 45 minutes from the 2.5Ah battery. On high speed, power increased noticeably for thicker weeds, but runtime dropped to roughly 30 minutes. The wheeled edger attachment is a thoughtful addition that helps you maintain perfectly straight edges along driveways and walkways.

The included 2.5Ah battery is a step up from the basic 2Ah packs found in many competitors. BLACK+DECKER claims 66 percent more runtime compared to their older battery, and the real-world testing supported that claim. The battery works with all BLACK+DECKER 20V MAX tools, which is one of the most affordable and widely available battery platforms.

Long-term durability is a mixed bag based on user reviews. Many owners report 5 or more years of reliable use, while some have experienced switch mechanism failures. BLACK+DECKER backs the trimmer with a 2-year limited warranty, which provides reasonable protection for the price point.

Best for Beginners and Casual Users

This trimmer excels for homeowners who trim occasionally and want something simple and comfortable. The AFS system and wheeled edger make it nearly foolproof for first-time trimmer buyers. The 20V MAX battery compatibility adds value if you own other BLACK+DECKER tools.

What to Watch For

The switch mechanism is the most commonly reported failure point. If you notice intermittent power issues, contact BLACK+DECKER under warranty. Also, avoid expecting this trimmer to handle thick, woody weeds, as the 0.065-inch line and 12-inch swath are designed for maintained lawns.

6. CRAFTSMAN V20 Trimmer and Blower Combo Kit – Best Combo Deal

The CRAFTSMAN V20 combo kit gives you a 13-inch string trimmer and a 90 MPH leaf blower for under $100, which is an outstanding value if you need both tools. The trimmer features automatic line advance and a telescoping pole for height adjustment. The blower pushes 340 CFM at 90 MPH, which is sufficient for clearing grass clippings, leaves, and light debris from driveways and patios.

I tested this kit on a small suburban property, and both tools performed adequately for light-duty work. The trimmer cut through standard lawn grass without issue, and the blower cleared grass clippings from a wide sidewalk in a single pass. The dual-speed control on both tools lets you balance power and battery life.

The biggest drawback is battery life. The included 2.0Ah battery provides only about 10 to 15 minutes of runtime per tool, which is quite short. You will likely need to trim and blow on separate charges, or invest in a larger battery if you want to do everything in one session.

Combo Value Assessment

Buying a trimmer and blower separately would cost significantly more than this combo kit price. If you need both tools and do not mind the short battery life, this kit offers the best dollar-for-tool value in our roundup. The V20 battery compatibility is a bonus if you plan to expand your tool collection.

Limitations for Larger Properties

This kit is designed for small yards and light duty only. The thin 0.065-inch string struggles with anything beyond maintained grass, and the short battery runtime makes it impractical for properties over a quarter acre. Consider the CRAFTSMAN CMCST901M1 listed above if you need longer runtime from a single tool.

7. Greenworks 40V Combo Kit – Best Quiet Operation

The Greenworks 40V combo kit stands out for its remarkably quiet operation at just 67 decibels, which is quieter than a normal conversation. If you have close neighbors or prefer early morning trimming without disturbing anyone, this is the kit to get. The package includes a 12-inch auto-feed trimmer and a 110 MPH, 390 CFM blower.

The trimmer weighs only 8 pounds, making it one of the lightest in our test group. The 40V motor provides noticeably more cutting power than 20V systems while maintaining that quiet operation. During testing, it handled standard lawn grass and moderate weeds without bogging down. The auto-feed system dispensed line reliably throughout our test sessions.

The included 2.0Ah battery charges in about 60 minutes and provides roughly 25 to 30 minutes of trimming time. The 40V battery platform is compatible with over 8 Greenworks tools, including mowers, chainsaws, and hedge trimmers. This makes it a strong choice if you plan to build out a full cordless yard tool collection.

The blower delivers 110 MPH and 390 CFM, which handles dry leaves and grass clippings well but may struggle with wet, heavy debris. The cruise control feature on the blower lets you lock the throttle at a comfortable setting for extended use.

Quiet Operation Benefits

At 67 decibels, you can use this trimmer without hearing protection and without bothering neighbors. This is especially valuable in dense suburban areas or townhouse communities. The gas trimmers in our roundup operate at 90 to 100+ decibels for comparison.

Battery Platform Advantage

The Greenworks 40V system is one of the most extensive battery platforms available, with over 8 compatible tools. If you plan to eventually replace gas tools for mowing, hedge trimming, or pruning, investing in this combo kit gives you a head start on building a complete cordless yard care system.

8. EGO POWER+ ST1502SA 15-inch with Battery Included

The EGO ST1502SA is the older sibling of our editor’s choice pick, and it comes with a significant advantage: the 56V 2.5Ah battery and charger are included in the box. For buyers new to the EGO ecosystem, this saves you the additional cost of purchasing a battery separately. It ranks as a top 5 bestseller in Amazon’s string trimmer category with over 3,100 reviews.

The 15-inch cutting swath is slightly narrower than the ST1610T but still covers ground efficiently. The Rapid Reload head lets you restring without taking the head apart, though it is not quite as effortless as the POWERLOAD system on the newer model. The variable speed control lets you dial back power for lighter trimming to extend battery life.

In testing, the brushless motor delivered consistent power through thick grass and moderate weeds. The battery lasted about 50 minutes on a single charge, which was enough to trim my entire test property. The split shaft design means you can attach other EGO tools like edgers, pole saws, and cultivators to the same powerhead.

The main complaints from long-term users center on the auto-feed system, which can be unreliable and occasionally jams. Some users also noted that the cutting line sits slightly high off the ground, making low trimming difficult. Despite these issues, the overall rating of 4.2 stars across 3,100 reviews indicates strong user satisfaction.

Comparing EGO Models

If you already own an EGO battery, the ST1610T with POWERLOAD is the better choice for its carbon fiber shaft and easier line loading. If you need a battery and charger, the ST1502SA gives you a complete package at a competitive total price. Both share the 56V brushless motor and IPX4 weather resistance.

Split Shaft Versatility

The split shaft design extends the value of this trimmer well beyond basic weed eating. You can purchase EGO attachments to convert it into an edger, pole saw, hedge trimmer, or brush cutter. This makes it one of the most versatile platforms in our roundup for users who want a multi-tool system.

9. Echo eFORCE 56V DPAS-2100SBC1 – Professional Attachment System

The Echo DPAS-2100SBC1 brings professional landscaping pedigree to the battery-powered market. Echo is a brand trusted by landscapers, and this trimmer is part of their Pro Attachment Series, meaning the powerhead accepts up to 15 different Echo-approved attachments. You can convert it from a trimmer to an edger, blower, hedge trimmer, brush cutter, or even a cultivator.

The Speed-Feed 400 cutting head is one of the fastest line-reloading systems I have used. You thread the line through two holes, twist, and it winds automatically. It comes pre-loaded with Echo’s 0.095-inch Silentwist line, which runs quieter than standard round line while still cutting aggressively. The 16-inch cutting path covers significant ground per pass.

The included 2.5Ah battery delivers up to 28 minutes of runtime, which is shorter than some competitors. Echo offers a 5.0Ah battery option that extends runtime to about 58 minutes for larger properties. The variable speed trigger lets you manage power output, which helps stretch battery life during lighter trimming tasks.

Professional Grade vs Consumer Grade

Echo designed this trimmer for professional use, which means better build quality, longer warranty coverage, and attachment system compatibility. The 5-year consumer warranty and 2-year commercial warranty exceed what most battery trimmer brands offer. However, the limited runtime with the included battery makes it better suited as part of a multi-battery setup.

Stock and Availability Warning

At the time of writing, this trimmer shows only 4 units left in stock. If you are interested in the Echo ecosystem, do not wait. Echo products on Amazon tend to sell out during major sale events and may not restock quickly.

10. Husqvarna 122LK Gas Trimmer – Best Gas-Powered Value

The Husqvarna 122LK is a gas-powered trimmer designed for homeowners who want the unlimited runtime and raw power that battery tools cannot yet match. The 22cc 2-cycle engine spins the T25 trimmer head at 7200 RPM, and the 17-inch cutting width is among the widest in our roundup. Husqvarna’s SmartStart system reduces resistance in the starter cord by about 40 percent, making this one of the easiest gas trimmers to start.

In testing, the straight shaft design proved excellent for reaching under bushes, fences, and low-hanging branches where curved shaft trimmers cannot reach. The T25 Tap and Go head lets you bump the head on the ground to release more line, which worked reliably throughout our testing. The multi-tool compatibility means you can attach Husqvarna’s edger, pole saw, or brush blade to the same powerhead.

The trade-offs with gas power are familiar: noise, emissions, and the need to mix gas and oil. The 122LK operates at around 90 to 95 decibels, so hearing protection is mandatory. Vibration is noticeable after 30 minutes of continuous use, which is typical for 2-cycle engines in this displacement range.

At 10.6 pounds, it is reasonably light for a gas trimmer. The fuel tank holds enough for roughly 30 to 40 minutes of continuous trimming. Users on forums praise Husqvarna’s long-term reliability, with many reporting years of trouble-free operation with basic maintenance.

When Gas Makes More Sense Than Battery

If your property is over half an acre, has heavy brush areas, or you need to trim for more than an hour at a time, gas power still wins on runtime and cutting power. You never wait for a battery to charge, and refueling takes seconds. The 122LK is the best gas value in our roundup for homeowners.

Maintenance Requirements

Gas trimmers require regular maintenance including air filter cleaning, spark plug replacement, and proper fuel mixing at a 50:1 ratio. If you are not willing to perform basic engine maintenance, a battery trimmer will be more convenient. Husqvarna provides clear documentation, and parts are widely available.

11. LawnMaster 25cc Gas Trimmer with Electric Start

The LawnMaster 25cc gas trimmer tries to solve the biggest complaint about gas trimmers: hard starting. Its electric push-button start claims up to 150 starts on a single charge of the starter battery, eliminating the pull cord entirely. For anyone who struggles with pull-start engines due to age, strength, or shoulder issues, this feature is genuinely appealing.

The 25cc engine is the largest displacement in the under-$100 gas category, and it spins a dual-line bump-feed head with 0.080-inch line. The 17-inch cutting width matches the Husqvarna for coverage area. The split-shaft multi-tool design lets you swap attachments for edging, pruning, and other tasks.

Unfortunately, the execution does not fully match the promise. With a 3.6-star average rating and 21 percent one-star reviews, the LawnMaster has notable reliability concerns. The most common complaints involve the electric starter failing after minimal use and the engine shutting down when hot and refusing to restart until it cools.

When the trimmer works, it performs well for the price. The 25cc engine has genuine power for thick weeds and overgrown areas. But the inconsistent quality control makes this a risky purchase unless you are comfortable with the possibility of returns or warranty claims.

Electric Start Reliability

The push-button start is the primary selling point, but it is also the most failure-prone component. Some users report the starter working flawlessly for months, while others experience failure within weeks. If you decide to buy this trimmer, keep the box and warranty information handy for potential returns.

Is the Low Price Worth the Risk?

At under $100 for a 25cc gas trimmer with electric start, you are getting a lot of features for the money. However, the reliability issues mean you should set expectations accordingly. If you want a dependable gas trimmer, the Husqvarna 122LK is a safer choice for about $125 more.

12. Echo SRM-2620T High Torque Pro Gas Trimmer – Best for Heavy Duty

The Echo SRM-2620T is a professional-grade gas trimmer built for serious work. The 25.4cc high-torque engine is the most powerful in our roundup, and users describe it as a beast that handles any weed-cutting duty. If you have thick brush, woody weeds, or a large property with heavy growth, this is the tool that will not let you down.

The high-torque design means the engine maintains RPM under load better than standard trimmers. Where lesser trimmers bog down in thick grass, the SRM-2620T powers through. The Speed Feed head allows line reloading in under a minute without disassembly. At 6000 RPM under load, it delivers consistent cutting performance even in demanding conditions.

Echo is a brand that professional landscapers trust, and the build quality reflects that heritage. Users consistently praise the reliability, with many comparing it favorably to Stihl at a competitive price point. The engine starts reliably when properly primed, though flooding is possible if you over-prime.

The main consideration is whether you need this level of power. For maintained residential lawns, the SRM-2620T is overkill. But for properties with heavy brush, fencing rows with woody growth, or professional landscaping use, this trimmer justifies its premium price through performance and longevity.

Professional Landscaper Choice

If you run a landscaping business or maintain multiple properties, the SRM-2620T is designed for daily abuse. Echo backs it with professional warranty coverage, and replacement parts are available through any Echo dealer. The initial investment is high, but the long-term cost per year of service is competitive with cheaper trimmers that need frequent replacement.

Flooding Prevention Tips

The most common user complaint is engine flooding from over-priming. Follow Echo’s priming instructions exactly: press the primer bulb only the specified number of times. If the engine does flood, let it rest for 10 to 15 minutes before attempting to restart. Once you learn the starting procedure, flooding becomes a non-issue.

How to Choose the Best String Trimmer on Prime Day

Choosing the right string trimmer during Amazon Prime Day requires knowing your yard size, power preferences, and budget. The deals are only worth it if you buy a tool that actually fits your needs. Here is what to consider before you click add to cart.

Power Source: Corded, Battery, or Gas

Corded electric trimmers are the most affordable option and provide unlimited runtime, but you are tethered to an outlet. They work best for small yards near the house where extension cord management is not an issue.

Battery-powered trimmers dominate the market for good reason. They offer cordless freedom, quiet operation, and zero emissions. Modern brushless motors with 40V to 56V batteries deliver performance that rivals gas trimmers for most residential tasks. The main limitation is runtime, typically 25 to 60 minutes per charge depending on battery capacity.

Gas trimmers still reign supreme for heavy-duty work and unlimited runtime. If you have a large property, dense brush, or need to trim for extended periods without stopping, gas is the answer. The trade-offs are noise, emissions, maintenance requirements, and the need to mix fuel.

Battery Voltage and Runtime

Higher voltage generally means more cutting power. A 56V system like EGO delivers more torque than a 20V system, which translates to better performance in thick grass. However, higher voltage alone does not guarantee better runtime.

Battery capacity, measured in amp hours (Ah), determines how long the trimmer runs per charge. A 4.0Ah battery lasts roughly twice as long as a 2.0Ah battery at the same voltage. When comparing Prime Day deals, check whether the included battery capacity matches your yard size needs. A great price on a trimmer with a tiny battery may not be a deal at all.

Also consider the battery ecosystem. If you already own tools from a brand like CRAFTSMAN V20, WORX PowerShare, or Greenworks 40V, buying a trimmer that uses the same battery system saves money and adds convenience.

Cutting Width and Line Diameter

Cutting width ranges from 12 to 17 inches in our roundup. Wider cutting paths cover more ground per pass, which speeds up large jobs. Narrower paths offer better precision around flower beds and obstacles.

Line diameter affects cutting power and durability. Thinner 0.065-inch line works well for maintained lawns and light weeds. Thicker 0.095-inch line handles heavy weeds, brush, and rougher terrain without breaking. Professional-grade trimmers typically use 0.095-inch or heavier line.

Weight and Ergonomics

Trimming for more than 20 minutes with a heavy tool leads to fatigue and poor results. Look for trimmers under 8 pounds for comfortable extended use. Telescoping shafts, adjustable handles, and balanced weight distribution all contribute to a better user experience.

Gas trimmers tend to be heavier than battery models due to the engine and fuel. If weight is a primary concern, battery-powered trimmers in the 5.5 to 8-pound range offer the best combination of comfort and capability.

Combo Kit Value

Prime Day is an excellent time to buy combo kits that include a trimmer plus a blower, hedge trimmer, or other yard tools. The CRAFTSMAN V20 combo and Greenworks 40V combo in our roundup both offer outstanding value by bundling two tools with a shared battery at a lower combined price than buying separately.

Before buying a combo, verify that the included battery capacity is adequate for your needs. Some combo kits include small 2.0Ah batteries to keep the price down, which may limit runtime significantly.
