If you’re tired of yanking a pull cord forty times before your trimmer sputters to life, a cordless weed eater with the battery and charger in the box is the fix. The battery decides how much yard you can clear on one charge and which brand’s tools you can add later without buying new power packs. All nine trimmers below ship with the battery and charger included.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every kit here includes the battery and charger, so the only real question is how much cutting time you need. That is what this breakdown of the cordless weed eater with battery and charger covers.
Our Picks at a Glance



How To Choose The Best Cordless Weed Eater with Battery and Charger
You do not need to be a landscaper to pick the right one of these. You need to answer three honest questions about your own yard before you click buy. Get those right and almost any trimmer here will do the job.
Match the battery to the size of your yard
The two numbers that decide your runtime are voltage and amp-hours. Voltage is the muscle — a 60V battery pushes harder than an 18V one. Amp-hours (Ah) are the tank size, so a 4.0Ah pack runs longer than a 2.0Ah pack at the same voltage. A pack that runs out mid-lawn is the number one regret for first-time buyers, so if your yard is large, lean toward a bigger amp-hour battery or a kit that ships with two packs. A trimmer that dies mid-lawn just means another trip to the garage.
Decide whether auto-feed or bump-feed suits you
You get two ways to feed the cutting line. An auto-feed head releases fresh line on its own as the string wears down, so you never stop to adjust it. A bump-feed head asks you to tap it on the ground to feed more line. Both work — the difference is if you want to think about it at all. Auto-feed is the friendlier choice for anyone with a stiff wrist, and the bump systems earn their place when you’re cutting heavy growth and want manual control.
Think about the battery platform before the trimmer
Almost every brand here sells a whole family of tools that share one battery system. Buy into a platform with a battery you like, and your next leaf blower or hedge trimmer costs less because you already own the power pack. Check whether the battery in the kit works with the other tools you plan to buy.

In‑Depth Reviews
1. BLACK+DECKER 20V MAX String Trimmer and Edger 2 in 1 (LST300)
Our pick — over 4★ from 9,500+ verified ratings; the strongest balance of quality and price.
The featherweight that turns a weedy sidewalk into an edge job in seconds.
Here’s what makes this the pick for most people: it weighs 5.7 pounds, and that low weight is exactly why it feels easy from the first pass to the last. The 20V MAX motor spins the line at 6200 RPM — a measure of how fast the cutting string whirls, and the higher that number, the faster it slices through grass. For a trimmer this light, that is a genuinely useful combination, and it explains why it has become the default first cordless trimmer for so many households.
The trims and edges without missing a beat: the Automatic Feed Spool feeds fresh line on its own, so you never have to bump it on the ground to keep cutting. That auto-feed system is what wins people over the most, and it makes the 12-inch cutting swath — the strip of grass cleared in one pass — surprisingly productive for a compact unit. A 2.0Ah lithium-ion battery runs it, and the kit ships complete with the battery, a wall-mountable charging base, and one AF-100 spool. The two-in-one design converts from trimmer to edger in seconds, and the adjustable handle and height positions let you set it to your own posture rather than fighting it.
Now the honest part. A trimmer this light trades raw muscle for control, and it really shines on grass, mild weeds, and overgrowth around flower beds — not on thick saplings or deep-rooted brush. The runtime is steady but short, so if you have a sprawling property, plan on a spare battery. For a small to medium yard, though, it is the easiest and most reliable starter kit on this list. A handful of buyers report the included pack runs down faster than they would like, but the vast majority treat it as a complete, capable little machine.
Where it wins
- 5.7 pounds makes it easy to carry with one hand through a whole yard
- Automatic Feed Spool ends the bumping ritual entirely
- Converts from trimmer to edger in a couple of seconds
- 6200 RPM POWERDRIVE Transmission keeps the blade moving fast under light load
Where it gives ground
- Underpowered against thick saplings and heavy brush
- 2.0Ah battery runs about as long as a small yard takes to finish
- No wheeled edging guide — you hand-guide the edge
Reach for it if: you have a normal suburban yard, want a trimmer that feels weightless, and value easy assembly and setup over brute power.
Look elsewhere if: your property has saplings to clear or you routinely cut an acre or more in one session.
2. Greenworks 24V 12 in Cordless String Trimmer (ST24B217)
At 5.2 pounds it is one of the lightest here, and the telescoping shaft fits everyone from a teen to a six-foot gardener.
This is the pick for households where more than one person takes a turn at the trimming. A telescoping aluminum shaft adjusts to fit users from 4’8″ to 6’5″ — so a shorter teen and a taller parent both get the handle at the right height, without stooping. That fit is a big deal for longer sessions, because a poorly-sized pole pushes you into a hunched stance and strains the back. The 90-degree rotating head also means you can pivot the trimmer into awkward spots — tree roots, garden beds, sloped banks — without contorting your wrists.
The 24V system runs quieter than most. Greenworks rates it at 75 dB, about the noise of a vacuum cleaner, so early-morning and evening trimming works without annoying your neighbours. That quiet is a real selling point: this category is moving away from gas because battery-powered tools do not wake anyone up. The 2.0Ah battery delivers 30 minutes of runtime, and the kit ships with both the battery and charger, plus a 2-year warranty on the battery and a 3-year warranty on the tool.
The honest trade-off is power and torque at the low end. This trimmer does its best work on grass and light-to-medium weeds; against thick brush or saplings it has less muscle than the CRAFTSMAN CMCST901M1. Battery life is also fussy — the runtime number is solid, but a small share of owners find the pack degrades faster than they expected or reads low early. If your yard is a standard one and fit-and-quiet matter more than brute force, it earns its place.
The quiet advantage: 75 dB is quieter than the average vacuum, so HOA-restricted morning trimming is genuinely doable.
Line and fit: the.065-inch single-line auto-feed head resists jams, and the 5.2 pound build keeps fatigue down over long sessions.
If a hard-to-fit pole has been your problem: this one’s adjustable shaft and rotating head make it the most configuration-friendly option in the list.
If your yard is bush-heavy: the 24V motor may leave you wanting more punch against thick growth.
3. CRAFTSMAN V20 String Trimmer and Lawn Edger Kit (CMCST901M1)
A 4.0Ah battery and up to 63 minutes of runtime — the longest charge window on this list, and the reason it takes the runtime crown.
If yard size is your real problem, start here. This kit pairs a 4.0Ah V20 battery (a 4.0 amp-hour battery that stores more charge than a smaller pack) with the trimmer and chargers it in the box. CRAFTSMAN rates the runtime at up to 63 minutes — more than double the 30 minutes a 2.0Ah pack gives you on the Greenworks ST24B217. That is the difference between stopping to swap batteries mid-lawn and finishing the whole property on a single charge. The battery also works across the rest of the V20 line, so your next CRAFTSMAN tool will use the same pack.
The 13-inch cutting swath and the 52% more power claim (CRAFTSMAN’s own figure for this motor versus its predecessor) mean the wide path clears a lot of ground per pass. Two speed settings let you choose between maximum runtime and maximum cutting power, so you can dial in what the job needs. And the design is light and easy to maneuver, which matters when you are doing a long stretch of trimming. The Turn-To-Edge feature flips it into an edger without tools.
The one honest caveat is that durability is the split opinion on this tool. It does the trimmer and edger jobs well, but on heavy, continuous use some owners describe the build as lighter-duty than they expected. That is a fair note rather than a dealbreaker — the majority treat it as a strong value, especially the runtime. If you are a weekend yard worker instead of a daily operator, you will likely never notice.
What stands out
- Up to 63 minutes of runtime — the longest here
- 4.0Ah V20 battery is the biggest capacity pack on this list
- 13-inch swath plus 52% more CRAFTSMAN-claimed power
- Turn-To-Edge converts trimmer to edger with no tools
What to keep in mind
- Some owners describe the build as lighter-duty for hard, constant use
- Only ships with one spool, so a second is a smart add
The one to buy for a big job: the 4.0Ah battery and 63-minute rating mean most standard yards finish without a recharge.
However: if you need an all-day commercial-grade tool, consider a heavier-duty model instead.
4. CRAFTSMAN V20 Weed Wacker Cordless String Trimmer and Edger (CMCST900D1)
The CRAFTSMAN trimmer people keep buying again — a proven workhorse for thick grass and clean edges.
Power is where this one earns its reputation: the auto-advance.065-inch line system keeps cutting without a bump, and the two speed settings let you push hard at thick grass or stretch the runtime. The 13-inch cutting swath is wide enough to cover a lot of ground per pass. Buyers consistently praise it over the BLACK+DECKER 20V MAX LST300 for raw cutting authority, and it seasons its lighter-duty sibling with a heavier, more premium feel. The telescoping pole converts it to an edger quickly, and the integrated hook lets it hang on a wall rack, keeping your garage tidy.
On stamina, the honest story is mixed. The 2.0Ah battery performs well for a standard yard, but it is a smaller pack than the CRAFTSMAN CMCST901M1’s 4.0Ah. Some owners get through their whole yard on one charge, while others find a single session drains it. The practical answer: buy a spare 2.0Ah battery if you cut a lot, or step up to the 4.0Ah CMCST901M1 so runtime is bounded by the job, not the pack.
The build quality has earned this model a faithful following. Owners of large yards with gnarly weeds credit it with handling growth that rival trimmers choke on. The weight is a touch heavier than the smallest units here, so a strap helps on long sessions. For the price-to-power ratio, few options in this category beat it — it is the definition of a well-rounded yard-work buy.
The strength: customers rate this the best cordless trimmer they have owned, with power that handles thick grass and weeds without stalling.
The check: a 2.0Ah pack is small for hard use, so a backup battery turns this from good into great.
Built for the messy yard: if your spring growth is aggressive and you want a tool that bites into it, this is the heavyweight option.
Watch out for: the tight runtime on the included battery — add a spare if you cut weekly.
5. BLACK+DECKER 20V MAX Cordless String Trimmer and Edger (LSTE525)
Two batteries in the box means one is always charged — a small but genuinely useful upgrade over the single-battery kits.
The headline here is backup. This kit ships with two 20V MAX lithium-ion batteries plus the charger, so you can swap packs and keep working instead of waiting. The 2-speed control lets you boost power for heavy growth or drop to a gentler setting to stretch runtime. It converts from trimmer to wheeled edger, and the wheeled edging action is a real comfort win over hand-guiding an edge on the smaller BLACK+DECKER LST300. EASYFEED advances the line at the push of a button, so no bumping on the ground.
Where this version steps up over the base 20V model is the extra battery and the wheeled edger — two upgrades that matter in daily use. The 2.0Ah packs are small, and long sessions will chew through one, which is exactly why having two in the kit is the smart part of the design. Owners of the higher-capacity versions of the same tool report running much longer on a single charge, and if you decide you want that, the batteries are interchangeable within the 20V MAX system. It also shares its batteries with other BLACK+DECKER tools you may already own.
One thing buyers should watch for: the included packs can arrive older than expected, which is a common reality with older stock listings. That is a reason to buy from a fresh listing rather than a reason to skip the model. The trimmer itself is light, easy to handle, and durable — a sensible pick for small to medium yards where uninterrupted working time matters.
The case for it
- Two batteries and a charger in the box — no pause for a recharge
- Wheeled edger converts in seconds and takes strain off the arms
- EASYFEED button-release line advance keeps the work moving
- Lightweight and genuinely beginner-friendly — many buyers are first-time weed eaters
The catch
- Each 2.0Ah pack gives only a short session on its own
- Included batteries can arrive older than ideal on aging stock listings
When uninterrupted trimming is the priority: two packs here mean one is charging while you cut.
Better to skip if: you want a single battery that runs all afternoon — this kit trades capacity for redundancy.
6. NovorikX 60V Cordless String Trimmer with 2.5Ah Battery (XLST7B25-CA)
A 60V brushless motor that brings gas-style power to a battery trimmer — and a bit of gas-style weight with it.
If dense, overgrown greenery has beaten every 20V trimmer you’ve tried, this is where you jump. A 1200W brushless motor (brushless means fewer wearing parts and longer motor life) paired with a 60V 2.5Ah battery delivers power that owners describe as gas-like — able to churn through thick Bermuda grass without bogging down. The 17-inch cutting swath clears more ground per pass, and the dual-speed trigger toggles between 6100 RPM for hard cutting and 4600 RPM for lighter work around beds and fences.
Runtime lands at 27 minutes on the included 2.5Ah pack, and the 1-hour fast charger gets you back to work quickly when it does run down. The dual-line bump-feed head runs 0.095-inch reinforced nylon line and ships with three spare spools of 27 feet each, so you have enough line on hand for a full season. The power head is also compatible with other yard attachments, which opens the door to expanding later instead of buying new tools.
The trade-off is weight. At 15 pounds, this is one of the heaviest trimmers on the list, and the included strap is not the best. Long sessions take a toll on your arms and shoulders, so pacing yourself is smart. Assembly instructions are also a little thin, though most people get through setup on their own. A handful of owners have had to fiddle with the shield fit. For anyone cutting heavy growth on a decent-sized property, the extra muscle is worth the extra pounds.
Gas-like push without the gas: the 1200W brushless motor and dual-speed trigger make quick work of thick weeds that stall smaller trimmers.
Weigh the heft: at 15 pounds it wants a strap and a paced session rather than an all-day marathon.
The pick for overgrown land: if your property fights back, this trimmer’s 60V power and 17-inch swath finish the job faster.
Think twice if: you want something light enough to swing one-handed through a small yard.
7. RYOBI ONE+ 18V 13 in. Cordless String Trimmer/Edger (P20180)
If you already run RYOBI’s 18V ONE+ batteries, the math here is simple: this tool slots right into the platform you own.
The practical value is in the ecosystem. RYOBI’s 18V ONE+ line shares one battery across dozens of tools, so this 4.0Ah battery and charger kit gives you a pack that will power a RYOBI drill, blower, or hedge trimmer you may already own. The trimmer itself is light at 7 pounds, with a variable speed trigger for control and an adjustable cutting width that goes from 11 inches to 13 inches. The pivoting head turns it into an edger, and the auto-feed line head handles.065 or.080 line.
The 4.0Ah battery is the standout feature for runtime — plenty for a small yard trimming and edging session. The wheeled edging feature simplifies sidewalk work, and the lever flips between trimmer and edger modes in seconds. A 3-year warranty backs the tool. Combined, these traits make it a solid performer for a homeowner who wants one battery platform under the whole garage.
The honest caveats: the pole is long, and shorter users around 5’3″ may find it awkward, since there is no way to shorten it. Assembly instructions are also minimal, and one or two owners mention difficulty seating the pole properly. If you are tall enough that the length is comfortable and already own RYOBI batteries, this is a straightforward, well-built option.
What makes it click
- 4.0Ah ONE+ battery runs the whole line of RYOBI 18V tools
- Adjustable 11 to 13 inch cutting width adapts to the task
- Pivoting head and dedicated edger mode simplify edge work
- 7 pounds and a variable speed trigger for controlled, easy handling
What to weigh
- Fixed long pole may suit taller users better than short ones
- Assembly directions are minimal compared to other kits here
Ideal for existing ONE+ owners: the shared battery and charger make this almost a no-brainer within that platform.
Consider a different fit if: you are on the shorter side and want a pole that adjusts down.
8. Husqvarna WeedEater 320iL, 16-Inch, with 4 Ah Battery & Charger
Big-brand build with a power boost button and a reversible head — a serious tool for owners who want it to last.
Start with the feature almost nobody else on this list has: the dual-direction trimmer head. It reverses the cutting direction with a flip, which lets you trim around lawn edges while keeping clippings off garden beds and hardscapes instead of flinging them across your flowers. That one feature alone changes how you work near planting beds. Add the 16-inch cutting width — the second widest here, tied with the Greenworks 40V — and you cover ground quickly.
The Power Boost mode delivers 20 percent more power (the manufacturer’s figure) it steps up for heavy grass or thick weeds, and an active cooling system helps keep the motor running consistently over longer sessions. The touchpad controls start the trimmer instantly with a single touch, and an LED indicator shows on/off state. The 4Ah battery and charger ship in the kit, and the 3-year limited warranty covers the tool. Owners compare the 320iL favourably against premium competitors, noting it feels more powerful and has a wider cut than some rival models.
The one piece of feedback that recurs is the stock trimmer head — a few owners find it feeds line less smoothly than they want and swap in a better aftermarket head. That is a small fix, and the rest of the machine earns its reputation for quality. Battery runtime is also variable depending on the load, and the heaviest users have noticed the pack stops performing as strongly after hard use. For most homeowners, the 4Ah pack comfortably covers a full yard on one charge.
Built to stay in the shed for years: Husqvarna’s reputation for quality and the 3-year limited warranty make this a long-game purchase rather than a throwaway.
Max performance note: Power Boost adds 20 percent more power on demand for the thickest growth, while the active cooling system keeps the motor steady.
The right call for brand loyalty plus features: if you want a top-quality tool with a reversible head and boost power, this is a standout.
The caveat: the stock trimmer head is the weak point — plan to upgrade the head if you cut frequently.
9. Greenworks 40V 16 in Cordless String Trimmer (ST40L414)
The trimmer that grows into a whole yard-tool system, with snap-on attachments that change what it can do.
This is the future-proofing pick. Greenworks builds this 40V trimmer to accept interchangeable attachments — an edger, hedge trimmer, pole saw, cultivator, and blower all snap onto the same power head. So instead of buying five separate tools, you buy one power source and add heads as you need them. That versatility is unusual in this category, and it makes the 40V trimmer a smart buy for anyone planning to expand their yard toolkit over a few seasons. The 16-inch cutting swath is one of the widest on this list, and the 40V 4.0Ah battery gives it ample endurance for a half-acre or more.
The brushless motor (a motor with fewer wearing parts that runs cooler) delivers more power and longer runtime than a brushed unit. The two-speed modes with a variable speed trigger let you match the pace to the job — a slow mode works well near fences and delicate edges. Assembly is quick, and many owners describe the tool as beginner-friendly for a first home with a large yard. The 40V battery is shared across the Greenworks 40V system, so your next tool in that line can use the same pack.
The honest trade-off is weight. At 15.2 pounds, this is the heaviest trimmer on the list, and a few owners find it tiring after an hour with the battery on top. There is also a recurring complaint that the string binds in the spool sometimes when replacing line, and one owner reported a missing nozzle piece on a blower attachment. That aside, the machine handles thick weeds and blackberry starts with ease, and with a shoulder strap the weight becomes manageable.
Why it earns a spot
- Snap-on attachments turn one tool into an edger, hedge trimmer, pole saw, cultivator, or blower
- Brushless 40V motor runs powerfully with a wide 16-inch swath
- Two speed modes plus a variable trigger for control in delicate areas
- Shares its 4.0Ah battery across the wider Greenworks 40V platform
Where it asks for patience
- 15.2 pounds is the heaviest build here — a strap makes long sessions easier
- Replacing line in the spool can take some wrestling to get right
The pick if you want to expand: buy the trimmer now and add Greenworks attachments later rather than buying separate tools.
skip it if: you only need a trimmer and want something lighter to swing.
Understanding the Specs
Voltage and amp-hours together
Voltage is pushing strength; amp-hours (Ah) is tank size. A 60V 2.5Ah pack pushes hard but holds less total energy than a 40V 4.0Ah pack. Match the pair to the job: high voltage for thick growth, high amp-hours for long sessions. The CRAFTSMAN CMCST901M1 pairs 20V with 4.0Ah for maximum runtime, while the NovorikX 60V 2.5Ah packs big cutting power into a shorter window.
Cutting swath drives speed of the job
Cutting swath is how wide a strip of grass each pass clears, expressed in inches. A 16-inch swath covers noticeably more ground than a 12-inch one, so bigger swaths mean fewer passes and less time in the sun. The trade-off is that wider swaths need more motor torque to keep the line spinning, which is why the widest models here also bring bigger motors and heavier builds.
Auto-feed versus bump-feed line
Auto-feed releases fresh line automatically as the string wears, so you keep going without stopping. Bump-feed asks you to tap the head on the ground. Auto-feed suits uninterrupted work and stiff wrists; bump-feed gives you manual control. Neither is better in every case — it depends on if you want your hands free to guide the tool or your head free to think.
Weight and ergonomics for long sessions
The difference between a 5-pound trimmer and a 15-pound one shows up after twenty minutes of cutting. Lighter units like the 5.2-pound Greenworks ST24B217 or 5.7-pound BLACK+DECKER LST300 stay comfortable for long stretches and work well for one-handed maneuvering. Heavier units with bigger motors may need a strap. Adjustable shafts and pivoting heads also reduce strain by letting you work in a more natural stance.

Final Thoughts: The Verdict
For most yards, the cordless weed eeater with battery and charger winner is the BLACK+DECKER LST300 because its 5.7-pound build and no-bump auto-feed make trimming easy for a normal suburban lawn. If you want the longest single-charge window for a big property, grab the CRAFTSMAN CMCST901M1 with its 4.0Ah battery and up to 63 minutes of runtime. And for overgrown land that fights back, the NovorikX 60V XLST7B25-CA is the one to reach for — its 1200W brushless motor cuts through thick growth that stalls lighter trimmers.
