The GreenWorks Pro ST80L210 80V Cordless String Trimmer is a high-quality, battery-powered trimmer that has been welcomed with bells and whistles. Available at an affordable price, this trimmer is the perfect solution for customers looking to trim their yards to remove tough weeds and vegetation.

With so many string trimmers on the market, why do we find this particular string trimmer to be worth taking a closer look at? It might have something to do with being a cordless weed eater, having killer runtime so you can get your entire yard cleaned up in one go, AND the extra features it offers in one pretty nice package. While many people shy away from cordless, we find that when comparing electric vs gas weed eaters there are plenty of options in both camps to get the job done and done well! 

Ready to learn more? In this GreenWorks Pro ST80L210 review, you’ll find everything there is to know about this 80-volt dream of a string trimmer.



The first and foremost thing to consider when buying a string trimmer for your yard is the features. Let’s take a quick look at what sets this GreenWorks string trimmer apart from the crowd. 

Powerful 80V Battery

This weed eater uses a strong 2-amp Lithium-ion battery. It is capable of generating enough power to compete with a 32CC engine on a gas-powered trimmer, in terms of both runtime and trimming capabilities. With a second battery ready on the charger, you’ll pretty much always be ready to get any size lawn under control with this bad boy. 

Typical runtime with this battery is around 45 minutes — depending on exactly what you’re trying to cut through, of course. Lighter duty stray grass will allow a longer run time than trying to use it as a brush hog in lots of thicker vegetation. 


You’ll find that this particular trimmer is actually compatible with many trimmer attachments made for the average gas weed eater. Now instead of just whipping out typical weed eating in an easy go, you can swap things out to make this unit even more versatile! 

String Size

Using a 0.080 string size, you’ll be able to get the job done with a nice clean cut, spun by that powerful battery. Since it offers a dual line instead of just a single line, you’ll definitely get your work done easily and quickly. 


At just under 10lbs, this trimmer is not just great on cutting grass but great on your back, too! 

Super Clean

With no gas to mix, no oil to change, and zero emissions, this is by far the cleanest style of weed whacker you can buy! Just snap on the battery and get trimming!

GreenWorks Pro ST80L210 Review – FAQ

Are battery-powered string trimmers any good? 

The GreenWorks Pro ST80L210 80V Cordless String Trimmer is among the best-selling string trimmers on the market today, so at least this battery-powered string trimmer gets the job done. 

For the average suburban yard, there is almost no question that you’ll do just fine with a battery-powered weed eater for your average cleanup. If you’ve got a lot of tricky spots where the lawnmower can’t reach that will need a good hack down, or if you’ve got a fairly large lot (think country lots instead of typical neighborhood lots), then you might look elsewhere.

If you’re replacing a gas trimmer and looking at battery-powered, can you get your entire lawn cleaned up in an hour or two? In that case, with a 2-battery system, you can run this trimmer for about 45 minutes, then swap to the second waiting battery to finish out the job. If your lawn typically takes 3-4 hours to clean up with a gas trimmer, you might find the wait for batteries to get charged up far too irritating to go this route. 

But when it comes to the power to get the job done, a cordless string trimmer does a nice job of cutting the grass and making quick work of it. 

How do you use a GreenWorks string trimmer? 

Well, it’s pretty straightforward to use any string trimmer. Make sure the battery is fully snapped in, get into position, and pull the trigger! 

Of note, make sure you don’t bog the head down deep into the grass you’re trimming, so it doesn’t get snagged and tangled up around the head. Cut using the tips of the strings and you’ll be cruising right along! 

Can I use a brush cutting blade with this string trimmer? 

Yes. As we said, it fits many attachments, and being able to swap out the string for a brush cutter attachment is one of those handy swaps! 



Powered by an 80-volt battery, this cordless trimmer is the perfect option for customers looking for a powerful unit capable of cutting down all tough weeds and grass to make your yard tidy and clean. This cordless trimmer is easy to assemble and is quite light, making it perfect for both young and old users. 

Powered by an 80-volt battery, this weed eater has the capacity to accomplish challenging tasks similar to a gas-powered unit. This trimmer has a 0.080 cutting line and is capable of trimming for a record 45 minutes before needing a recharge. Customers looking for a powerful cordless trimmer will really enjoy purchasing this unit.

The GreenWorks Pro ST80L210 80V Cordless String Trimmer is what every homeowner should look to keep yards free from weeds.
