Written by Chris Briggs

If you want your garden to look at its best, then a strimmer is vital. With a strimmer you can easily create great border edges as well as cutting around awkward spots, such as fences, trees and garden furniture.

There are plenty of jobs in the garden where using a lawnmower simply wouldn’t be practical. With a battery-powered cordless strimmer, you can take on these types of jobs without the need to be attached to a nearby plug socket.

Cordless strimmers are not only more convenient to use but you can get to areas you might not otherwise have been able to reach when using one.

We’ve rated some of the best cordless strimmers currently available. In addition to looking at their key features, we’ve also rated their pros and cons so you can make an informed decision.

Let’s start with our best pick, the Black & Decker 36V Lithium-Ion Strimmer…

Best Pick: Black + Decker 36V Lithium-Ion Strimmer

A powerful and versatile strimmer – perfect for most uses

The Black & Decker 36V Lithium-Ion Strimmer comes with some key features that make it a great choice in most situations.

Firstly, the 36 V 2.0 Ah lithium-ion battery means you get plenty of power, which is always important when cutting overgrown areas. In addition to the power of the battery, this model also features E-drive technology, which also makes sure that overgrown areas are something this model won’t struggle with.

The cutting width is 30cm, so it’s suitable for use on larger gardens as well as smaller ones. It’s very comfortable to hold thanks to the dual handles and at 3.5kg, it’s not too strenuous to use for a long period. There are two power modes to select from – ECO and TURBO. ECO will prioritize battery life while TURBO gives you more power.

You have the option to buy this strimmer on its own or with the battery included. As you might imagine, it costs significantly more with the battery.

Pros

  • The 36V lithium-ion battery provides plenty of power
  • Is very capable of tackling overgrown areas thanks to E-drive technology
  • 2 power modes to choose from (ECO and TURBO) allow you to either get more power or preserve battery life

Cons

  • There can be some issues with the reliability of the batteries after extended use

Value Pick: WORX WG163E 18V (20V MAX) Cordless Grass Trimmer

Some great features at a bargain price

Our value pick is the WG163E 18V Cordless Grass Trimmer by WORX. WORX do a wide range of cordless gardening/DIY tools that are usually very high quality yet affordable and this strimmer is no exception.

Powered by a WORX 20V Max battery, it’s equally capable when it comes to both trimming and edging. For edging, it has 2 wheels, making it easy to ensure a straight line when cutting. The cutting width is 30cm.

There is also an extremely useful function known as Command Feed. Command Feed allows you to get more cutting line from the spool by simply pressing a button on the top handle of the strimmer. This is very handy since it’s a much more complicated process with many strimmers. 

You have the choice to buy this as the body only, with 1 battery or with 2 batteries. If you can afford to, then it’s a good idea to get the 2 battery and strimmer bundle. Not only are the batteries much cheaper when bundled with the unit compared to buying them separately, but it’s very convenient to be able to charge one battery while you’re using the other.

Pros

  • Incredible value for money, with the option to purchase with 2 batteries and a charger for only a small increase in price
  • Very easy to assemble and use
  • The Command Feed facility makes it incredibly easy to get more cutting line as you need it

Cons

  • At 3.94kg it’s on the heavier side, which might be an issue for some

It’s powered by a 20V 2.5Ah li-ion battery, which although isn’t as powerful as some other strimmers, still provides enough power to tackle most jobs in small and medium gardens.

Ryobi OLT1832 18V

A feature-rich and high-quality strimmer

The Ryobi OLT1832 18V Strimmer has some excellent features that make it a great choice for owners of small to medium gardens.

An extremely useful feature of this model that often isn’t seen in other strimmers, is that you can adjust the cutting width. This makes it very versatile and easy to use for different types of tasks whether you’re cutting grass and weeds or creating edges.

It’s powered by an 18V rechargeable battery, which being honest is on the lower end as far as power is concerned, although this isn’t necessarily an issue, providing you’re not cutting any grass/weeds that are very thick and overgrown.

It weighs 2.3kg, so it’s certainly on the lighter side, which is always good news, especially if you’ll need to use it for extended periods of time. It’s comfortable to use overall and cutting head can be adjusted to four different angles, with the shaft being very easy to adjust too.

It’s worth noting that this strimmer is sold as body only, which means it doesn’t come with a charger and battery so you will need to buy these separately.

Overall, this is an excellent strimmer that will be able to take on pretty much every task in smaller gardens.

Pros

  • Part of the ONE+ system, which means you’re able to use the battery across a wide range of other garden or DIY tools
  • Four cutting angles mean you can easily cut down grass, weeds etc. in awkward spots
  • Very easy to assemble and use

Cons

  • A charger and battery aren’t included as standard and will need to be bought separately
  • The 18V battery means there isn’t a great deal of power, so more battery-sapping tasks such as cutting thick grass/weeds might be a struggle

Are Cordless Strimmers Actually Any Good?

If you’re thinking of getting a cordless strimmer, then you’re most likely wondering if they’re any good. The truth is, that just like many other cordless tools, they have their pros and cons.

The obvious benefits of a cordless strimmer are that they’re easy to use, can be used anywhere and you don’t have to worry about finding a nearby power source.

The downsides are that they’ll generally be more expensive than electric and petrol models and the batteries will usually need to be recharged after each use.


Whether a cordless strimmer is right for you will depend on your budget, the size of your garden and how important cordless functionality is to you.

Things to Consider When Buying a Cordless Strimmer

Not all cordless strimmers are the same and it’s not always as simple as the more you spend, the better quality you can expect. Knowing the most important things to look for will help you to make an informed decision and avoid getting the wrong strimmer.

With this in mind – Below are some of the most important things to consider when buying a cordless strimmer –

  • Weight – Weight is always an important consideration when you’re buying a cordless strimmer. These units can be quite strenuous to use, especially for a long period of time, so you should certainly think about the weight of any models you’re considering.
  • Voltage – The amount of power a cordless strimmer has will be determined by the voltage. Most cordless units for domestic use will be between 20 and 40v. You can get more powerful strimmers than this, but you should think about whether you need the extra power because this can add to the price considerably. 
  • Battery capacity – Battery capacity is another key thing to consider. Although the voltage will determine how much power a strimmer has, the battery capacity will determine how long you can use it before it needs recharging.

How To Use A Cordless Strimmer

Using a cordless strimmer isn’t too difficult, but there are certain things you should know in order to operate it safely and get the best results.

Before you start using a strimmer, it’s vital to ensure you have the right protective gear. At a minimum, you should always wear good quality gardening gloves as well as protective eyewear, but you should also consider wearing earmuffs and a helmet.

You should also prepare the area you’re going to be working on by removing anything you might trip over.

In order to use a cordless strimmer most effectively, you should bear a couple of things in mind. First is the cutting direction…

The best cutting edge of a strimmer will be the one that’s opposite to the direction the lines rotate. For example, if a strimmer spins anti-clockwise, then this means the grass will be ejected on the left side, making the right side the best to cut on since it will give you the best view of what you’re doing.

The second thing you need to remember is that the most power is contained at the ends of the strimming lines. A lot of people mistakenly believe that the closer they go to the grass, the better the cut will be, but this is not the case. You’ll get the best cut by cutting with the ends of the lines.
