Weeds and brush can be quickly eliminated with a string trimmer, allowing you to take joy in maintaining your own lawn. But if you’ve never purchased a string trimmer before, you likely don’t know what to look for when buying one.

We’ve done the tedious task of trying to find the best weed wacker, but there are some key important things you need to consider, too:

  • Battery Life: A low battery life of under 20 minutes will suffice for smaller yards and condos. If you have a larger yard, you’ll need a longer battery life. This is why many professionals use gas powered models because they never know how large a yard may be.
  • Automatic Feed: An automatic feed ensures less string breakage and also makes using a string trimmer easier. Most homeowners that don’t want to fuss with bumping a string will find that the automatic feed option is a great investment.
  • 2-in-1 or 3-in-1 Design: Most, but not all, string trimmers will offer 2-in-1 options, or a trimmer / edging There is one item on our list below that lets you mow the lawn, too, but with a small swatch radius, this may be impractical for larger yards.

Buyer’s Guide –  How to Choose the Right Battery Powered String Trimmer for You

You’re almost ready to make your purchase, but you’re stuck trying to decide which model to choose.  This is something that we’ve spent a lot of time trying to decide ourselves, so we know how difficult it can be to pick the right model for your needs.

Battery Powered String Trimmer

There is a lot that goes into the decision process:

  • Yard size
  • User strength and age
  • Experience

An experienced landscaper may not need an automatic feed system, but a person that has never used a string trimmer will appreciate the automatic feed and lack of bumping.

A few points that will make your decision easier are:

  • Price: String trimmers that are more expensive may not even have more features, but they’re better made, allowing them to be used for years without worrying that they’ll break in the process.
  • Size: The size isn’t as much of a concern as the weight of the unit. Ten pounds may be light for the first ten minutes, but then the weight will begin to put strain on your muscles, making it uncomfortable to carry. You may want to consider height adjustments, especially if you’re a taller person, as bending over to remove weeds is not fun.
  • Type: Battery-powered string trimmers are ideal for small to medium-sized yards. This is because they don’t require cords or gas. But large yards will take longer to trim, and a low battery life can cause you to have to stop and charge the unit, which is an inconvenience. Buying additional batteries (some models come with them) will allow you to trim even larger yards with a battery-powered string trimmer.
