With the best electric weed eaters, you can say goodbye to unwanted greenery and tidy up your garden in a flash. Everyone knows how quickly weeds can become an unwanted feature of your garden but, with one of these handy tools, keeping a handle on your shrubbery has never been easier.
As with the many varieties of garden weed, there are some differences in the best electric weed eaters you can use to take care of your greenery. The options compiled here are all electric, and therefore more eco-friendly than gas alternatives, as well as quieter and less messy. Available with both cordless and corded power supplies, it’s worth assessing how long you want your weed eater to run for whilst you’re out in your garden. Corded models can run for as long as you need, but cordless models can go further afield as they don’t need to be attached to power (though they will need charging up).
Depending on how extensively your garden needs to be pruned, it’s also worth noting how powerful your chosen model is, to make sure you can completely rid it of weeds. The cutting stance of your weed eater is also important, as the wider the cutting stance the easier it is to deal with large areas at one time.
1. RYOBI RY40204A: Best electric weed eater overall
It’s hard to find a negative about the RYOBI RY40204A and we think it’s the best cordless electric weed eater on the market. It’s powerful, without the limitations of being corded, the battery has enough power to keep you trimming for over an hour and it’s quick to recharge too. It’s also quite light, so it’s not going to put extra strain on your back or muscles.
It doesn’t have the same range of adjustability as other models on this list, so if you need to tailor your weed eater for height or mobility needs, the Black + Decker LST300 might be a better option. However, it does have edging capabilities so you can adjust the head for both trimming and edging your yard.
It also has some nice features you won’t find on any other model on this list. The adjustable cutting width allows you to choose whether to save battery power or quickly breeze over your lawn. The variable speed is also another nice feature that allows you to choose how to trim.

2. Greenworks 21142: Best corded electric weed eater
If you’ve got some doubts as to whether an electric weed eater could ever measure up to a gas-powered one, then the Greenworks 21142 deserves a closer look. It is almost double the weight of most electric weed eaters, but that’s because it’s designed for power and durability.
It has an impressive 18-inch swath, so you can cover a greater area quickly, while the dual string means it easily dispatches even thick weeds. The lack of edging features is a bit of a disappointment and this is not a great option for small, hard-to-reach areas.
The Greenworks 21142 offers great value for money too. It’s not the cheapest on the market, but at around $70, it’s still very affordable, especially considering the cutting power it offers. A corded model may be inconvenient for some, but a battery-powered model with this much power would be more expensive.

3. Black + Decker LST300: Best electric weed eater for hard to reach spots
The Black + Decker LST300 Electric Weed Eater is a versatile trimmer and edger that’s designed to tackle small gardens and hard-to-reach spots with ease. While the battery power is good, there are better battery-powered options for larger areas, like the RYOBI RY40204A.
If you already have one or two battery-powered Black + Decker products then you might find their batteries are compatible with this weed eater too. As the weed eater only comes with one battery and has quite a long charge time, this would be particularly useful.
The Black + Decker LST300 Electric Weed Eater is both lightweight and quiet, making it a pleasure to use. It also offers the ability to adjust the weed eater, so you can set it to a more comfortable setup for you.

4. Worx WG163: Best premium electric weed eater
The Worx WG163 is the priciest electric weed eater on this list, but it’s also an adaptable option that comes with a spare battery too. While it does take a while to recharge the batteries, you can keep one charging while the other is in use and swap them out if the first dies before you’ve finished.
The head is adjustable, moving through 90 degrees so it can adapt to a range of terrains. When using the Worx Weed Eater as an edging tool it becomes wheeled for extra ease of use too.
The patented line-feeding system allows you to feed through more string with the push of a button. With the free replacement spools for life that come with this weed eater, you won’t need to worry about the cost of string replacement either. With the two-year warranty too, the Worx WG163 has been created with longevity in mind.

5. Sun Joe TRJ13STE: Best budget electric weed eater
At just $30, the Sun Joe TRJ13STE is a bargain electric weed eater. It does have less power than the other models on this list, so it’s not best-suited for tough weeds and overgrowth, but it is light and easy-to-use so perfect for lawn trimming. It does have a tendency to work through spools quickly, so it’s worth keeping in mind the cost of replacement spools when deciding whether this model is for you.
The four degrees of cutting is a nice feature that allows you to adjust the weed eater to the terrain you need to trim. The 13-inch swath is a good cutting swatch, but it is smaller than that of other models like the Greenworks Corded String Trimmer. The cord can be a bit inconvenient, but the cord hook is a nice little feature that helps keep it out of the way.
As a budget model, it’s not going to be especially powerful, but it still manages to offer a good range of features and a two-year warranty. It’s not a great option for anyone looking to take on a big yard clearing project, but it can trim across a variety of terrains with ease.

Gas vs. electric weed eaters
Professional landscapers usually prefer gas weed eaters for a few reasons: power and unlimited time and reach. In other words, gas models don’t limit you by the distance of a cord or battery life. Professional landscapers also need all the power they can get for jobs like clearing large fields of tough weeds and scrub. As such, gas weed whackers are often the best choice for serious yard work.
For most people though, an electric weed eater is more than up to the job. For a start, they’re easier to use than their gas counterparts, but have enough power to trim and edge a lawn and keep most weeds that spring up around the yard under control. Electric trimmers also create much less noise pollution and have zero emissions, which is a huge benefit to you, your neighbors, and the environment.
Important features to consider when choosing an electric weed eater
When looking for a new string trimmer, pay attention to the design, power options, string features and warranty. For instance, most of the trimmers we reviewed are cordless, and batteries are a nice convenience but they don’t last forever. A corded trimmer may be a good fit for a small yard. The following considerations will help you select the best electric string trimmer for your lawn.
Because you will be carrying around the weed eater, its overall weight is an important consideration. We compared how heavy the grass trimmers are, as well as if they have an adjustable shaft length for extra, customizable comfort. A dedicated edging position makes it easier to get a precise cut against sidewalks without having to hold your trimmer at an odd, uncomfortable angle.
Straight-shaft weed trimmers let you stand further away from what you are cutting, which keeps you safer. Safety is important, so we also looked to see if the trimmers we reviewed include devices that keep cords from getting in the way, as well as if the starter switch is protected from accidentally starting.
Power and battery
One of the most important things to consider when purchasing an electric string trimmer is if it has the power you need to accomplish the type of work you do. We looked for weed whackers that have high amps for corded models and high-voltage batteries for cordless ones. The more power a weed trimmer has, the tougher the grass and weeds it can tackle. We evaluated and compared cordless and corded electric string trimmers and found that regardless of the power source, if you choose a trimmer with enough power, you can trim efficiently.
When choosing between a corded and cordless weed eater, consider the type of work you need the trimmer to do and the size of your yard. Buying a trimmer that requires an extension cord limits your mobility, but that may not be a problem if you have a small yard. The advantage of using a cord is you don’t have to worry about the battery eventually dying and needing to be replaced. However, a cordless trimmer gives you limitless mobility, so it’s likely the best option if you have a large yard or need to trim in a remote location.
We looked for trimmers that are easy to restring and have great line-feed capabilities. The width of the cutting path is also important to consider when you choose an electric trimmer. Look for a grass trimmer with a cutting path wide enough to clear large areas with each sweep, yet narrow enough for you to use in tight spaces. The average cutting path is 13.5 inches wide.
Warranty and support
The industry-standard warranty for electric string trimmers is one year. We looked for trimmers that met or exceeded this standard. The manufacturers of the best electric string trimmers also provide repair or service center locations and phone or email support. A downloadable owner manual comes in handy if you happen to lose your print copy and need to look up a part or procedure.
Maintaining your electric weed eater
While electric trimmers don’t require nearly as much maintenance as their gas counterparts, there are things you can do on a regular basis to keep them running well for an extended period. Kristi Howard, of Black & Decker Outdoor Products, says that a common problem with electric string trimmers involves people using the wrong gauge of extension cord to power them. Howard says you should be sure to use an extension cord that is heavy enough to carry the current your product will draw.
“An undersized cord will cause a drop in line voltage resulting in loss of power and overheating,” Howard explains. “When in doubt, use the next heavier gauge.” She says the letters WA on the cord jacket indicate a cord that is suitable for outdoor use. Regarding corded versus cordless trimmers, Howard feels they are comparable in terms of power. Corded trimmers are generally less expensive than battery-operated trimmers and are easy to maintain, but they have less mobility.
To properly maintain an electric trimmer, Howard suggests checking for damaged parts and cleaning off the air intake slots before each use to avoid overheating. She says you should never immerse an electric string trimmer in water or clean it with a pressure washer, and you should store it indoors, out of reach of children. “Keeping your trimmer regularly maintained should minimize your need for larger repairs,” Howard adds.
