Are you in the market for a new string trimmer? Have you gotten tired of the hard to start small gas engines on your existing string trimmer?  If so you might want to take a look at the best battery powered string trimmer of 2021.

Why choose a battery powered string trimmer?

There are a few reasons why you might want to choose a battery powered string trimmer over a gas string trimmer.

  • starts easily and every time
  • lighter weight
  • no mixing of fuel
  • no fuel storage
  • much quieter than gas trimmers

I personally switched to all electric outdoor equipment recently and I am not looking back.

Gas vs Electric String Trimmers

So what are the major differences between gas and electric trimmers then?  I would say the major difference is convenience.  Electric string trimmers are much easier to deal with.  I am sure if you have used a gas powered string trimmer in the last decade, you have had to deal with mixing fuel.

Mixing the Gas

With an electric trimmer, there is no gas or oil or anything like that to deal with, so all you really have to do is make sure your battery is charged.  Did I mention how convenient battery powered outdoor tools can be?

Not that mixing gas takes an aerospace engineering degree, but it is a pain.  This usually reared it’s head when I had to go to the local home center and buy those small bottles of oil to mix up the gas.  I never seemed to have one when I needed it.  Even when I got it mixed there was no guarantee it would start.

Why won’t this thing start?

So electric string trimmers always start, because all you have to do is put a battery in or plug it into the wall and pull the throttle trigger.

Gas trimmers can be extremely hard to start.  If your fuel has been sitting too long, or you forgot to add an Ethanol additive to your fuel, then starting the trimmer can be a real pain.  Anyone ever broke a recoil starter?  I have.

Gas Trimmers are so Loud

So now you have the trimmer started, but it sounds like a go cart running at top speed.  No trimming for you early in the morning when the temps are nice an cool. The neighbors won’t like that.  Also, don’t forget about that exhaust smell.

Electric trimmers, for the most part, are quieter, I won’t say quiet.  You have the whirling noise of the string as it spins, but you don’t have the high pitched whine of the motor.

Gas Trimmers are Heavy

You’re trimming away at your landscaped beds or sidewalks, and you start to feel your arms getting tired, and you’re only halfway through trimming.  My old gas trimmer weighed a ton, not literally, but it was heavy.  I had to eventually give in and use a shoulder strap to offset the engine weight.

My electric trimmer, on the other hand, is not heavy.  I do have a motor and battery to contend with, but compared to my old gas trimmer, this thing is light.  The great thing is I didn’t experience a loss of power when switching to a battery powered trimmer, you can’t beat lightweight and powerful.

    • Actually the Ryobi model in this article only takes a .080 line. However they do have a brushless trimmer that takes .095 line.

  1. I was curious about the 60v Dewalt myself. A little more expensive but the Dewalt name carries some weight.
