Benefits of Cordless Weed Eaters

You’ve likely heard that Battery Powered, cordless weed eaters are considered superior to trimmers with extension cords. But the benefits of cordless weed eaters go far beyond the fact that there isn’t anything tethering you to an outlet.

Freedom of Movement

The obvious benefit is that you can go anywhere without managing the cord. Furthermore, you’ll never have to worry about getting cords tangled around your bushes or delicate flower gardens being trampled by them.

One not-so-obvious reason that cordless trimmers are better than their corded counterparts is that you will never need to worry about what type of power cord to get for your trimmers.

No Toxic Fumes

To be fair, gas weed eaters are also cordless ones, but as I stated earlier, we’re focused on battery-powered weed eaters today.

Weed eaters fueled by gas give off unpleasant odors, and sometimes even downright dangerous fumes are emitted from them. The worst part is that the motor is often only a few inches away from your body, making it nearly impossible to get away from those fumes.

An electric weed eater has none of those problems. With a cordless trimmer, you can put away your breathing mask and enjoy the scent of freshly cut grass that we all love so much.


Cordless weed eaters aren’t as powerful as gasoline-propelled ones, but they are much stronger than weed eaters that need to be plugged in. Nothing is quite as frustrating as the trimmer line getting caught in the weeds you’re trying to cut down.

Battery-operated trimmers usually have more powerful motors, so it is something that you probably won’t ever experience if you keep up with your lawn regularly.


Cordless weed eater string trimmers will always be lighter than gasoline trimmers. The motors are more minor, have fewer moving parts, and no tank is attached to house the fuel.

If you want something lightweight, you should look for a cordless weed eater.

Features To Consider for “Cordless” Weed Eaters

Most of you already know you want a cordless weed eater. But that doesn’t mean that everyone knows the best features to consider before going cordless. Let’s factor in some considerations before you purchase a wireless trimmer.


Cordless weed eaters (particularly the more powerful ones) tend to cost more than gas-powered weed eaters using extension cords.

Battery-powered technology is pricier than other yard trimmers due to the manufacturer’s cost to produce Lithium-Ion batteries. (Think Prius, or worse yet – Tesla:)

However,  the prices for Cordless Weed Eaters have dropped considerably in the last two years, and the comfort and convenience you get by going Cordless – are well worth the initial price tag.


Earlier, we mentioned that today’s best Battery Operated Weed Eaters are likely more potent than those requiring an electrical Cord.  Suppose you have an extensive property or intend to do professional yard work.

In that case, you will probably need a longer duration and overall power than that provided by a Cordless String Trimmer.

If that is the case,  you might consider a top-rated Gas Powered weed eater. However, for 90% of the homeowners reading this article, a good quality Cordless trimmer will be just what you need.

Most of us using weed eaters strictly for residential reasons are fine with battery-operated trimmers.

Battery Life

As with anything powered by batteries, you only have a limited time before you plug in your battery and let it recharge. Many manufacturers of cordless weed eaters remedy this by shipping two batteries with their product.

And if they don’t, you could always purchase another one or use the battery from your cordless leaf vacuum blower.

If you have a giant yard that takes a lot of time to weed, you may be better off purchasing a gas-powered weed eater.

The second aspect of battery life is how long the battery lasts before you need a new one. If you’re buying batteries every six months to a year, you aren’t saving any money vs. using a gas weed eater. Instead, you are simply spending that money on batteries for your weed eater.

Make sure you get a weed eater with batteries that will last a few years.

Wrapping Up

We do hope our extensive research reviewing the best Battery Powered String Trimmer models has helped you decide which product is best for you and your budget.  Our top 5 choices were based on all of the features, customer satisfaction, and experiences.

Recommendation: If you have the budget and you’re looking for the best Heavy duty Battery Powered Weed Eater and don’t need to maintain Dewalt’s battery compatibility system, the EGO ST 1502 is, in our opinion, the Best Cordless Weed Eater on the market!

For Homeowners on a Budget, we believe the best option is still our number 1 pick, the  Black+Decker LSTE525 Trimmer & Edger
