Top 9 Cordless Weed Eaters – Reviews 

1. Remington 40-volt cordless electric string trimmer

Remington RM4000 40V 12-Inch Cordless Battery String Trimmer and Edger

The Remington 40-volt cordless electric string trimmer is lightweight, easy to use, and we love the adjustability of this model. You can change the length of the shaft to fit your trimming style, and the head rotates 90 degrees to help with edging.

We also like the price — this is one of the more inexpensive machines on our list. 

Worth noting: The 40-volt battery capacity could be a little more impressive, as could the Remington’s cutting width. Also, the three-year warranty is pretty standard. 

Specifications:

  • Power: 40 volts
  • Maximum cutting width: 12 inches
  • Weight: 7 lbs
  • Battery capacity: 2.5 Ah
  • Price range: inexpensive
  • Warranty: 3 years

Pros:

2. RYOBI 40-volt cordless attachment-capable string trimmer 

RYOBI 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer, 4.0 Ah Battery and Charger Inc

This cordless Ryobi string trimmer has a lot going for it: We love the four amp-hour battery capacity, which makes this machine a great choice if you have a large yard or don’t want the hassle of stopping to recharge.

Bonus points: With a strong 40-volt motor and a 15-inch cutting radius, this model can keep your yard trim and neatly edged. 

The RYOBI 40-volt only loses points for its weight. This one’s a little on the heavy side at 11.3 pounds.

Bottom line: If you’re looking for an all-around good value in the medium price range, we recommend taking a look at this cordless weed eater. 

Specifications:

3. Scotts 20-volt cordless string trimmer

Scotts Outdoor Power Tools LST02012S 20-Volt 12-Inch Cordless String Trimmer, Black

The Scotts 20-volt takes the No. 3 spot with an affordable price tag and a lightweight design. This cordless weed eater is ideal for anyone with a small yard or garden who wants to be able to quickly trim up their property with a lightweight machine at a fraction of the cost.

With this model, you will be sacrificing cutting power. We don’t recommend it for anyone with thick or woody weeds. The limited cutting width makes this little string trimmer most suited for edging light turf. The battery life is nothing to write home about either, so make sure you keep this one charged. 

Specifications:

  • Power: 20 volts
  • Maximum cutting width: 12 inches
  • Weight: 4.5 lbs
  • Battery capacity: 2 Ah
  • Price range: inexpensive

4. Snapper XD 82-volt MAX cordless electric string trimmer

Snapper XD 82V MAX Cordless Electric String Trimmer Kit with (1) 2.0 Battery and (1) Rapid Charger

Are you looking for raw power in your weed eater? The Snapper XD 82-volt has the most powerful cutting capacity of any battery-powered string trimmer in our survey. This machine also has a wide cutting radius. It’s perfect for powering through dense patches of weeds or stiff grass.

If you have a lot of land to clear, this model may be suited for your needs. We also love the exceptional 5-year warranty. 

With great power comes great weight and cost. This trimmer is certainly on the expensive end of the market. It’s also one of the heaviest machines in our survey, weighing in at nearly 20 pounds. The battery life could also be a bit more impressive. 

Specifications:

  • Power: 82 volts
  • Maximum cutting width: 16 inches
  • Weight: 19.76 lbs
  • Battery capacity: 2 Ah
  • Price range: expensive

5. ECHO 58-volt brushless cordless string trimmer

Echo CDST-58VBT 58-Volt 58V Lithium-Ion Brushless Electric Cordless String Trimmer - 58V. Battery and Charger Not Included

The Echo 58-volt lithium-ion brushless string trimmer is another powerful weed eater. We like the strong voltage and the wide cutting radius.

Anyone who needs a heavy-duty machine that can tackle serious jobs will like this machine. It’s not quite as powerful as the Snapper XD above, but it is much lighter. And similar to the previous model, we love the substantial warranty. 

This model loses a few points for price. If you want a powerful trimming machine, you’re going to have to put up some cash. The battery life also could be much longer. Two amp hours is well on the low end of the spectrum. 

Specifications:

  • Power: 58 volts
  • Maximum cutting width: 16 inches
  • Weight: 10.5 lbs
  • Battery capacity: 2 Ah
  • Price range: expensive
  • Warranty: 5 years

✗ Expensive 
✗ Moderate battery life

6. Greenworks 40-volt cordless string trimmer

Greenworks 40V 14inch Cordless String Trimmer (Attachment Capable), 4.0 AH Battery Included 21362

The Greenworks 40-volt weed eater has a lot going for it:

  • We love the long warranty. This is a solid buy for anyone who doesn’t like having to replace their equipment.
  • The power and cutting radius are more than enough to tackle even heavy-duty weed whacking jobs.
  • We also love the battery life. If you have a large property, or just don’t like having to plug in your machines all the time, this model would make a great addition to your tool shed. 

There are only a couple of strikes against this weed eater:

  • This string trimmer is a little on the heavy side. We don’t recommend this model to anyone who may have difficulty carrying 13 pounds around for an extended period of time.
  • The second strike is cost. The Greenworks 40-volt is going to be in the upper price tier, though you do get a good machine for the money.   

Specifications:

  • Power: 40 volts
  • Maximum cutting width: 14 inches
  • Weight: 13 lbs
  • Battery capacity: 4 Ah
  • Price range: expensive
  • Warranty: 4 years

Pros: 

✓ Warranty
✓ Power
✓ Battery capacity

Cons:

✗ Weight
✗ Price

7. Toro PowerPlex brushless 40-volt cordless string trimmer

Toro PowerPlex 51482 Brushless 40V Lithium Ion 14" Cordless String Trimmer, 2.5 Ah Battery & Charger Included

This Toro weed eater has great cutting power, and we really like the substantial cutting radius and strong electric motor.

This cordless trimmer also offers great versatility. The variable cutting speeds allow you to find the right balance of cutting power and battery life for your home improvement project. This model also features a lightweight design, making chores easier. 

However, this weed eater loses points in a few places. It’s definitely on the pricier end of the spectrum, the battery capacity is nothing to write home about, and the warranty is well on the shorter end of the market. 

Specifications:

  • Power: 40 volts
  • Maximum cutting width: 14 inches
  • Weight: 8.4 lbs
  • Battery capacity: 2.5 Ah
  • Price range:  expensive
  • Warranty: 2 years

Pros: 

✓ Powerful
✓ Lightweight
✓ Good cutting radius

Cons:

✗ Low battery capacity
✗ Short warranty
✗ Expensive

8. Greenworks 24-volt string trimmer

Greenworks 24V 12 inch String Trimmer, 2Ah USB Battery and Charger Included ST24B215

The Greenworks ST24B215 is ideal for anyone looking for a lightweight and inexpensive trimmer. If you have a small yard or garden, and don’t need a lot of cutting power, this might be the machine for you.

We also appreciate the versatility of the USB port, which allows this tool to be plugged into a wide range of outlets. The adjustable aluminum shaft allows 90 degrees of rotation, making this one easy to use. 

As far as downsides go, this model doesn’t pack a lot of power, and the battery capacity could also be stronger.

Overall, though, this is an ideal weed eater for basic trimming. 

Stats:

  • Power: 24 volts
  • Maximum cutting width: 12 inches
  • Weight: 8.28 lbs
  • Battery capacity: 2 Ah
  • Price range: inexpensive

Pros: 

✓ Affordable
✓ Lightweight

Cons:

✗ Moderate power
✗ Low battery life

9. TACKLIFE 20-volt cordless 2-in-1 string trimmer

String Trimmer, TACKLIFE 20V 10-Inch Cordless String Trimmer, 2-In-1 String Trimmer&Edger, Muti-Angle Head, Length Adujstable, Lightweight, 2.0Ah Battery And Charger Included

The TACKLIFE 20-volt is one of the easiest-to-use string trimmers on our list. The extremely lightweight design makes this machine ideal for anyone to use. We also love the versatility of this model. The rotating head allows you to switch back and forth between trimming and edging.

The price tag is also hard to beat. If you’re mainly interested in a machine that’s affordable and easy to use, be sure to give the Tacklife 20-volt a look. 

This model loses a few points for cutting power, cutting radius, and battery life. If you need a machine that can cut through wide swaths of thick weeds, you might look elsewhere. Anyone who considers battery capacity a dealbreaker, also probably should keep looking.  

Stats:

  • Power: 20 volts
  • Maximum cutting width: 10 inches
  • Weight: 5.8 lbs
  • Battery capacity: 2 Ah
  • Price range: inexpensive

Pros: 

✓ Very lightweight
✓ Affordable

Cons:

✗ Small cutting width
✗ Low power
✗ Short battery capacity

Buyers Guide to Cordless Weed Eaters

What kind of weed eater should you buy?

Weed eaters have one of three sources of power, so weigh the strengths and weaknesses of each. 

Corded electric: Corded electric weed eaters need to be plugged into an outlet. You’ll have to drag an extension cord behind you and be careful not to get tangled up in it.

Corded electric weed eaters are often powerful and affordable, but they’re not ideal for people with large properties or sparse outdoor outlets. 

Gas: A gas trimmer is going to be much more portable than the corded electric variety. These trimmers are powered by combustion engines that can pack a serious punch.

However, the gas weed wacker has its drawbacks. These machines can be loud, and they emit harmful emissions. Gas weed eaters also take a lot of maintenance, making it easy to ruin your engine if it is not cared for properly. 

Battery: Battery-powered weed eaters combine the best of both worlds. Powered by lithium-ion batteries, cordless models are easy to maintain and easy on the environment while offering all the portability of a handheld combustion engine.

Depending on the model, you might sacrifice some power in going with batteries. However, the 60-volt engines will cut through weeds just as effectively as most gasoline-powered models on the market. 

Check out this video breaking down the differences between gas- and battery-powered weed eaters: 

Cordless weed eaters: key metrics

If you have never bought a cordless weed eater before, all of the statistics can be confusing. Let’s define some of the key terms: 

Power: You’ll want a weed eater that can cut cleanly through thick grasses and weeds. This will take a little spinning power. Battery-powered machinery uses volts as a measure of electromotive force. The higher the volts, the more spinning power. 

Maximum cutting width: This measurement simply tells you how much grass you can cut with one swipe. This is the diameter of the cut made by the spinning strings. You may want a smaller cutting width for trimming hard-to-reach spaces, but a larger one allows you to cut more grass at once. 

Battery capacity: Everything powered by batteries will eventually need to be recharged. How soon you need to recharge depends on the model and the quality of the battery.

Amp hour (also referred to as ampere hour, and abbreviated as Ah) is a unit of electrical charge multiplied by time. One amp hour represents a battery’s capacity to put out one amp of electricity for one hour. The more amp hours, the longer your run time.

Weight: The importance of weight will depend on your individual needs. If you’re training to become a bodybuilder and think yard work is a good chance to get a few reps in, you won’t mind trimming weeds with a 13-pound machine. For those needing a more lightweight option, there are plenty of string trimmers offered between 5-7 pounds.

Price: You want to get a good value for your money, so we weighed the cost of the weed eaters on our list. Cordless weed eaters can range widely in price, but depending on your budget you should be able to find a capable machine within your specific needs and parameters.

Warranty: A warranty is a company’s guarantee to replace broken parts within a given time frame. A company that gives a longer warranty stands more strongly behind the quality of its product.

If you plan on keeping your machine running year after a year, you will want a longer warranty from the manufacturer. 

FAQ about Cordless Weed Eaters

1. What’s the best cordless weed eater I can buy?  

By our measurements, the Remington 40-volt cordless electric string trimmer has the best-rated combination of power, cutting width, battery capacity, weight, cost, and warranty. We find this to be the best cordless weed eater on the market right now. 

2. What are some of the major brands of weed eater?

In making this list we researched great options by Greenworks, Remington, Ryobi, and many others. If you’re still interested in shopping around, you’ll find more weed eaters from DeWALT, Makita, BLACK+DECKER, Husqvarna and Worx.

3. Should I get a corded or cordless weed eater? 

This largely depends on whether you’re more interested in portability or affordability. If you have a small lawn, you can get extension cords up to 100 feet.

If you have a large lawn or would just rather invest in something more portable, battery-powered weed eaters may be a better option. 

4. How long can I run the trimmer on one battery charge?

This will depend on the battery capacity of your particular weed eater. Amp hours are a measurement of electrical output as well as time, so a machine that requires more electricity may not last as long.

In general, we find weed eaters trim anywhere from half an hour to an hour and a half before you need to break out the charger.

Conclusion 

Now that you’ve got a firm grasp of the top 10 cordless weed eaters and what to look for in this tool, you should be ready to get that clean cut, perfectly edged yard you’ve always wanted.
