The 8500rpm spin speed is perfect for tougher grass and some weeds so will neaten up any area after the lawnmower has finished its job.

E drive technology is a high torque gear system that can power through tough grass without clogging up. It also has power select so you can adjust it between eco mode for normal trimming to save battery life and turbo mode to cut thicker grass.

It has an auto-feed spool which keeps the line topped up as needed. This saves stopping and starting and the 30cm cutting diameter gets the job done quickly.

This trimmer is a powerful and effective garden tool and the ergonomic handle plus lightweight body makes it easy to use. It’s great for trimming long grass as well as an edger tool and is an all round, brilliant product.

2. Runner Up – Einhell Cordless Lawn trimmer

In second place we have Einhell with their answer to battery-powered trimmers. This li-ion battery powered trimmer is very easy to use thanks to the telescopic handle and the second adjustable handle which gives you excellent control.

The cutting head is made from sturdy plastic blades that will deliver a good cutting swathe with each use. The universal, 18V battery can be used in a number of different power tools like the Einhell hedge trimmer and power drill so is a great option if you have any of these already.

This is a good garden strimmer with plenty of power to get through thick, long grass but isn’t so well designed for edging. It’s perfect for tidying up the lawn or for use in small gardens with thick grass as a mini-mower.

It comes with a plant guard to keep those flowerbeds neat and the powerful battery technology means this can handle large gardens if you don’t mind waiting for the batteries to charge.

4. Best Budget Option – VonHaus Cordless Grass Trimmer

If the price is the top consideration then be wary when looking for a new electric strimmer. A lot of the apparently very cheap options are sold as the body of the strimmer only, no battery or charger included. This strimmer by VonHaus has the best of both worlds. It’s very cheap and it comes with the battery and charger included in the price!

The 20v max battery has a runtime (no load) of up to 50 minutes and is rechargeable in 1 hour so you can cover fairly large areas with it. The cutting head uses strong nylon blades and has a plant protector, an edge guide wheel plus an adjustable head for neat edging.

The pole is adjustable so you can set it to a comfortable height for you and the rubber, soft grip handles make it comfortable to use.

It’s not the most powerful model and you won’t have much luck using it as a brush cutter to tackle brambles. It is a lightweight, ergonomic design that’s pleasant to use and will give your lawn beautiful neat edges after you mow.

5. Best For Lawn Edges – Webb 20 Volt Cordless Grass Trimmer

It’s a really effective little strimmer with the power of a corded model yet the freedom of a petrol strimmer. All this and the price is really great too!

Electric Strimmer Buying Guide

Battery Life

The battery life of your electric strimmer is an important consideration when buying the tool. A short battery life will mean you have to stop more often to recharge the batteries so will take longer to cover a wide area.

Most cordless trimmers will run for up to 30-45 minutes on a full charge. This time will be affected by how much work the strimmer needs to do (ie long or thick grass will mean more power needed) as well as grass conditions is wet vs dry grass.

The time needed to re-charge the battery can be anywhere from 1 – 5 hours so if you have a large area needing done, you’ll want a battery that’s quicker to re-charge.

Battery Power

The power of the battery indicates how well it will cut the grass. A more powerful battery will cut through grass easier so will get through a larger area quicker.

The power of the battery is given in both volts and amp hours. To keep it simple, the voltage is similar to the power the battery needs to work, and the amp hours are how long it can go for. For example, a 36v battery with 2.5Ah will be a lot more powerful and work for longer than a 20v battery with 1.0Ah.

Area Needing Trimmed

The area of grass needing trimmed must be considered in relation to the power of the battery and the cutting width it can handle. A larger area and you will need a more powerful battery plus a larger cutting width. If you have a small area needing done or it’s very narrow then you’ll want a strimmer with a smaller cutting diameter.

Blades vs Line

Electric trimmers generally come in two forms. Line trimmers or plastic blades. The line trimmers do break easily but a simple spool feed system will keep it topped up so you can keep on working despite a small break in the line.

The plastic blades are pretty effective at cutting grass but if you hit a solid object they break very easily. You have to stop strimming to replace them so it can add a bit of time and hassle on to your day. The plastic blades are also prone to getting clogged up with longer grass so this can be a pain.

Weight

The strimmer needs to be light enough that whoever is using it can do so without struggling. The benefit of cordless electric strimmers is they are generally very lightweight by design. I’ve included all the weights in the product description so you can make sure you choose one that will suit you.

Accessories/Extras

Edging wheels, flower guards, ergonomic handles, auto feed, and power adjustment are some of the many features that electric trimmers have. These can all help make your job easier and leave you with a tidy lawn.

F.A.Q.s

Are battery powered Strimmers any good?

Battery powered strimmers are lightweight, quiet, easy to use, and have excellent maneuverability. They can get to places that corded strimmers can’t manage and are much nice to use compared to petrol ones. The downside is, they’re nowhere near as powerful as a petrol strimmer and the batteries don’t last very long.

What’s the difference between a trimmer and a strimmer?

There’s actually no real difference between a trimmer and a strimmer. Different brands will classify certain products as one or the other but the word strimmer is actually just a contraction of the words grass-trimmer.

Are Strimmers with plastic blades any good?

The plastic blades trimmers are tougher and more durable than line fed ones (even dual line ones). They can handle tougher plants but they do break when they hit solid objects. They’re also prone to getting clogged up with longer grass and can be a pain to stop and sort them out.

How long do cordless trimmers last?

Cordless trimmers usually last about 30-45 minutes of continuous use (1 hour being the upper limit). The batteries can take anywhere between 1hr to 5 hrs to charge so this can slow down the job at hand quite significantly.

Can a strimmer cut long grass?

For longer grass and weeds, an electric strimmer generally isn’t powerful enough. You really need a petrol strimmer to handle these tougher jobs.
