What are The Benefits of Buying a Cordless Weed Eater?

The benefits of cordless weed eaters go far beyond that. Namely, there isn’t anything tethering you to an electrical outlet, and there are no sparkplugs, gas, or pull-cords to mess with.

You’ve likely heard that battery-powered (cordless) weed eaters are superior to trimmers with extension cords. The benefits of cordless weed eaters go far beyond that. 

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

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 leave unpleasant odors, and sometimes even downright dangerous fumes are emitted. 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.

Battery Power:

Battery-powered tools generally last considerably longer now than the older (12-volt) battery equipment, which was limited to around 15 minutes of run time.

How long do Battery-powered Weed Eaters last?  The most popular weed eater (string trimmer) category is the Lithium-Ion 40-Volt battery equipment, and the Greenworks 40-Volt Weed Eater, for instance, has an average run-time of 45 minutes using their 2.0 Ah (Amp Hours) battery.  

However, if you upgrade to a 40-volt (4.0 Ah) battery, the run time increases to an average of 60 minutes.

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 aren’t made of steel, have fewer moving parts, and no gas tank is attached to house the fuel.

Consider a battery-powered weed eater if you want something lightweight.

What are the Best Features for “Battery-Powered Weed Eaters”

You may already know you want a cordless weed eater. But you may not know the best features to consider before going cordless. Let’s factor in some considerations before you purchase a wireless string trimmer.

1) Price

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 of producing lithium-ion batteries. (Think Prius, or worse yet – Tesla vs. Ford)

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.

2) Power (Voltage)

Earlier, we mentioned that today’s 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 so,  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 OK with battery-operated trimmers.

3) Battery Storage (Amp Hours – Ah)*

As with anything powered by batteries, you 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 low-Ah 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. 

The second aspect of rechargeable batteries is how long they last before charging. For instance, a 4.0 Amp Hour battery lasts twice as long as a 2.0 Amp Hour (Ah) battery.  Higher Amp Hour batteries cost considerably more than low Ah versions.

This value is reflected in Ego’s trimmer at 3.0 Ah vs. the more inexpensive Black +Decker trimmer with 1.5 Ah.  Personally, and with my size yard, I prefer to spend more money on Ah batteries and have them last for the 20-30 minutes I need to use my string trimmer.

*Amp Hours (Ah) determine the Storage or Longevity of a battery before it needs to be recharged.

Our extensive research on the best battery-powered string trimmer models has helped you determine which product is best for you and your budget. 

Our top 5 choices were based on the features and customer satisfaction we experienced; therefore, we can recommend them.

Recommendation: If you have the budget and you’re looking for the best 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
