Top  6 Best Battery Powered Weed Eater Review

1. Earthwise LST02010

Earthwise LST02010


  • Voltage: 20 volts
  • Line speed: 8,800 RPM
  • Cutting swath: 10 inches
  • Line diameter: 0.065 inches
  • Weight: 4.4 lbs

The top pick isn’t the biggest or strongest weed eater, but it overcomes it with its lightweight design, ease of use, and affordability.

Earthwise customers report that the long-lasting lithium-ion battery on their LST02010 model lasts them over a year of yard work. Despite its 10-inch cutting swath, this tool can really come in handy when you’re working on long jobs.

In terms of ease of use, there is nothing better than the Earthwise LST02010. This cordless weed eater is one of the lightest available and can be carried for long periods of time.

As a result of the LST02010’s auto-feed spool, it’s easy to load, and a flip-down edge guard enables us to easily edge around landscaping beds in a more convenient manner.

A great thing about this Earthwise model is that it costs about $65. This weed eater offers incredible value for the price. For simple household chores, you should choose the Earthwise LST02010 string trimmer.

2. WORX WG184



  • Voltage: 40 volts
  • Line speed: 7,500 RPM
  • Cutting swath: 13 inches
  • Line diameter: 0.08 inches
  • Weight: 8.6 lbs

The WORX WG184 is one of our favourite weed eaters. RYOBI picks easily convert into wheeled edgers, and like our Greenworks picks, they have a variable speed trigger so you can change the RPM as your grass type changes.

Moreover, the adjustable handle allows you to work in comfort at any angle, and the pivoting head makes it easy to navigate uneven and sloped surfaces.

The WORX WG184 also offers great convenience along with versatility. By pressing a button, users are able to load a new line into the tool using the Command Feed automatic spooling system.

Despite weighing 8.6 pounds, it’s light enough to carry for extended periods even though it’s heavier than many of our other choices.

The WG184 is on the expensive side at around $150 due to all these features. With 40 volts of cutting power, this string trimmer comes packed with two 20-volt batteries that can be used with all 20V and 40V tools of the WORX brand.


  •  The voltage is high
  •  Convertible into a wheeled edger

  • Voltage: 40 volts
  • Line speed: 8,600 RPM
  • Cutting swath: 15 inches
  • Line diameter: 0.08 inches
  • Weight: 11.3 lbs

A battery-powered tool manufacturer like RYOBI comes next in our top picks. A string trimmer with 40-volts and a lot of special features comes as a result of that experience.

Its biggest advantage is its “expand-it” attachment system, which allows this one tool to do the work of several.

The variable speed trigger on this RYOBI model allows you to adjust the speed of the string to either save power or extend battery life. As an additional power saver, the cutting width can be adjusted from 13 to 15 inches.

The 40V string trimmer from RYOBI has significantly more power and size than the top pick from Earthwise, but it comes at a higher cost. With a price tag of about $170, this tool is our most expensive.

When you need the extra power, this is an excellent choice, but for the average lawn, you should be fine with the Earthwise LST02010 (and save about $100).


  •  Attachments of all kinds are available
  •  Cutting swath of large size
  •  Voltages that are high
  •  Battery life extension through variable speed control


  •  It’s expensive
  •  A heavy weight

4. Greenworks 21302

Greenworks 21302


  • Voltage: 40 volts
  • Line speed: 9,000 RPM
  • Cutting swath: 13 inches
  • Line diameter: 0.065 inches
  • Weight: 9.3 lbs

It is easy to maneuver and has plenty of power combined with the size and price of this cordless string trimmer from Greenworks. With a 40-volt battery, the device runs at a high speed of 9,000 RPM, allowing it to cut through thick, tough weeds with its blade (string). The cutting swath of this machine has a length of 13 inches, which is plenty large enough to handle regular household tasks.

Unlike string trimmers, the Greenworks 21302 does more than just trim grass. In addition, it can be used as a wheeled edger because its head can rotate 90 degrees. Telescopic shafts help you reach hard-to-reach places when weed wacking or edging.

Depending on your lawn’s conditions, cordless electric power tools run for varying amounts of time on a single charge, however, the 2.0 Ah battery in this weed eater is quite capable of lasting an average of one hour. You should be able to trim your lawn around an average size in that amount of time.


  •  RPMs are high
  •  Voltages are high
  •  Easily converts to a wheeled edger


  •  Heavy compared with other top picks
  • Some people find it difficult to hold down (especially for arthritis sufferers).




  • Voltage: 20 volts
  • Line speed: 9,000 RPM
  • Cutting swath: 10 inches
  • Line diameter: 0.065 inches
  • Weight: 5.2 lbs

Black+Decker is offering a great deal on this product for around $100. With the LCC222 string trimmer/edger, you also get a leaf blower (small leaf rake) for clearing fallen leaves.

The kit comes with two lithium-ion 20V MAX batteries that are included in the package, so in the event that the first one doesn’t work or runs out of power before you have finished the job, you’ll have a backup.

A lightweight 5.2-pound unit, the LCC222 features an automatic feed spool that makes it easy to use. There have been many reports from users that say this weed eater is even louder than other electric weed eaters, which makes it perfect for noisy neighborhoods.

Although less powerful and smaller, this model comes with a tradeoff. Due to the battery’s lengthy charging time and short run time, it is not suitable for larger properties.


  •  Budget-friendly
  •  It is lightweight
  •  Edger converts to a cutter
  •  Contains sweeper tool and batteries
  •  High RPM


  •  Insufficient voltage
  •  Cutting swath of small size
  •  Charge time is long, run time is short

6. Greenworks 21342

Greenworks 21342


  • Voltage: 24 volts
  • Line speed: 9,000 RPM
  • Cutting swath: 12 inches
  • Line diameter: 0.065 inches
  • Weight: 8.8 lbs

The Greenworks 21342 is closely related in many ways to the Greenworks 21302 weed eater from the same brand. There are generally a few differences, including a smaller size, a weaker engine, and a lower price. It allows you to save money while still getting the benefits of a Greenworks product without the cutting power of a 40-volt battery.

With pivoting head and telescopic shaft, this model is equipped with improved maneuverability and converts to a wheeled edger.

It is still possible for the 21342 to move its single line at 9,000 RPMs even with its weaker battery, even with its weaker battery. There is no doubt that the weaker battery on the Greenworks 21342 directly contributes to a shorter run time, as it typically lasts only about 25 minutes on a single charge.

Several users reported that this model doesn’t work well with the auto-feed line, even though it’s technically included. This weed eater will make it more difficult to load the string, so assume this will be the case for practical purposes.


  • Cost-effective
  • There is a high RPM
  • Wheeled edgers can be converted from it


  • Low voltage
  •  Batteries run out quickly
  •  Automatic feed does not work

Buying Guide – Best Battery Powered Weed Eater

Factors to consider

To determine which specific model might be best for you, you should compare a number of factors after deciding you want a battery-powered weed eater.

Here, we’ll talk about the factors to consider when choosing the best battery-powered weed eaters to suit your needs.


It is important to consider the weight of the weed eater, since you will be carrying it around your yard. The heavier the weed eater, the faster you will wear yourself out and the longer you will be able to use it.

Make sure you choose a weed eater that compliments your upper body strength. Carrying weed eaters can be made easier with shoulder straps.


A battery-powered weed eater can be purchased for as little as $100 or as much as $500 depending on the model. It may be more expensive to buy larger models with more voltage, so determine what is right for your yard in terms of affordability and functionality.

This list focuses on weed eaters under $200 because we consider price a significant factor. There is typically a significant difference between premium and commercial grade weed eaters.

Line speed

The string (the “blade”) rotates at RPM (rotations per minute). In the same way that voltage is better for tough, dense grass, so is higher RPM or line speed.

Cutting swath

By determining the cutting swath (or width) is an important step in determining how long a certain area will take to trim. In general, weed eaters with a 10-inch cutting swath will take longer than using one with a 15-inch cutting swath because it can only cut 10 inches at a time. Nevertheless, if you plan to trim in tight spots, you might want to choose a smaller cutting swath.


In order for a battery to be powerful, it must have a high voltage. It is advisable to use a higher voltage for heavy-duty work (such as trimming thick, overgrown grass and weeds, etc.).

It is usually more expensive to get more power. Saving money or taking on more challenging tasks depends on your priorities.

Line diameter

It holds a certain diameter (or thickness) of line when it uses weed eaters. For residential use, all the weed eaters listed here hold strings between 0.065 and 0.08 inches in diameter. A commercial-grade weed eater is built to handle heavy-duty usage, and it will have thicker strings, but it will also cost a bit more.
