Best Electric Weed Eater: All Cordless Options

Cordless electric weed eaters didn’t used to be great with low battery life, long charge times, and minimal power. A lot has changed within the last decade. The following equipment on this page are the best weed eaters that have very similar features.

Since last year, I’ve become a big Greenworks fan. In my post about the new Greenworks electric mower, you can see some of the reasons why it is a great buy.

Even since last summer, there have been many other brands that I’ve noticed starting to gain traction in the electric market. Brands like Black+Decker, Toro, and even Dewalt branded electric trimmers.

Since it was a big move from a gas mower to an all-electric machine (with just batteries!) I have been thinking about getting the matching Greenworks weed eater. One of the neatest features of the Greenworks line-up is the ability to swap batteries between all of the tools.

One of the areas that Greenworks stands out (at least in the beginning) was the 40V option. Since many other cordless options were lower, 40V batteries are really the turn-around in the electric equipment industry.

In case you aren’t aware, this is really the beginning of using a battery that is consistent in power and actually provides capabilities for the outdoor work trying to be completed.

What is the Best Electric Weed Eater (or Trimmer) Right Now?

Although the marketplace is going to change, within the last couple of years to the present, many weed eater models have come out with their own set of features, so it’s hard to answer, “What’s the absolute best?”

For example, some come with a guide that folds down to help prevent cutting down plants, others will have a high or low switch to conserve battery power.

One of the biggest factors I think about is: does it do anything else? Can it also be an edger?

In previous years, power has been an issue. Trying to get the same power in a cordless weed eater that doesn’t have a physical connection to an outlet has been tough.

Now, with newer lithium-ion technology, batteries are stronger, more consistent, and provide equivalent power to a corded weed trimmer.

Without being partial to Greenworks (just because I own their mower) I thought it would be fair to list out other similar cordless electric weed eaters.

If you have used a corded weed eater before, you know the struggle! Walking over the cord, yanking it back and forth as you walk around, and of course, being short-handed when you need it most.

Another problem arises with gas weed eaters. You have to worry about mixing the oil and gas (just right) and then filling it back up once empty.

It’s not a surprise that manufacturers are moving to more of an electric society and it makes sense. Plus, most of the equipment comes with a two or three year warranty covering regular use of the weed eater or trimmer.

I’m really big on having an #electriclawn and hope to move all the way to electric equipment for my yard. Ideally, the mower can be replaced, the trimmer, chainsaw, and other tools out there that are used each year. 

Stay tuned for another related post to electric lawn equipment!
