Yet another cordless strimmer, but the Black Decker has a power control option that can extend the battery life and allow you to do more work in your garden. The power control is adjusted based on the work you need to get done; a tough job may call for more power, but a simple trim calls for less power.

This strimmer is robust and works well when you have a large garden that needs some tending to. You are also able to switch from trimming to edging quickly, and the guide wheel helps you achieve even edges. My father always wanted the cleanest edges possible, and this would be a perfect option for those crisp edges.

Greenworks Cordless Grass Trimmer

The power, however, can only last for about 20 minutes and limits the time you can spend in the garden. This cordless strimmer has an adjustable handle and can rotate to allow for an edging option.


  • 30cm cutting diameter
  • One battery that is interchangeable with many products (specific to Greenworks products)
  • Plant guard is included


  • Short battery life
  • Buying the base unit does not come with a battery and a charger.

What features should I look for?

The strimmers we’ve looked at each contain a variety of features that can suit the needs of different gardeners.

The battery life from one charge, whether it is cordless or cable, the line feed options, and the possible handle and cutting head adjustments are some of the features that may have you considering different strimmers.

Here is a quick breakdown of a few features you can consider when looking to buy a strimmer.

Battery life

For most heavy-duty tasks, such as running strimmers, batteries may last, on average, about 30 minutes. This allows for plenty of time to trim the grass and do the edging of your garden.

Multiple batteries and larger batteries solve the problem of having a larger garden but not enough battery life to complete all of the work.

Using a cable strimmer is also an alternative to exclude the worries of battery life. With a long extension cord, you are able to get all the work done, regardless of how long it may take.

Is the strimmer cordless or not?

Deciding to go cordless may seem daunting, and you may feel dubious, but cordless strimmers have many benefits and can make your work in the garden quick and easy.

Cordless strimmers allow you to work in any section of your garden without having to use an extension cord. The lithium-ion battery found in more units are reliable and can be charged numerous time to keep on giving the best performance time and time again. You may be concerned about the long charge time, but developments in technology allow for fast chargers to get the battery up and running in a fraction of the time.

All these strimmers’ cordless options are very convenient, but if you only need a strimmer for occasional use, then a cable strimmer could be a viable option. Cable strimmers are also a great contender if you have a very small garden, and you only need to do the basics.

Line Feed Options

Replacing the line of your strimmer can be a tedious process, but the automatic feed makes it much more comfortable, and you only have to refill the line once it’s all finished.

Always check the line size of the strimmer and buy the correct size. Strimmer line is freely available, and different thicknesses are available depending on your needs in the garden. Some strimmers may accommodate a variety of lines, but others may only support a very specific size.

Handle and Cutting Head Adjustments

A telescopic handle and adjustable cutting head allow for a large variety of configurations that can make using strimmers much easier and comfortable. The size and shape of the handle and pole can make a big difference in my experience.

An adjustable cutting head gives flexibility when you need to do edging or trim at an odd angle. The head can be adjusted and readjusted as the demand changes.

Bare unit or not?

A bare unit refers specifically to the unit that does not include the battery or a charger.

Bare units are the best option for a gardener that already has equipment from a specific brand and has batteries for the machine. A bare unit saves some money and eliminates the need to have a battery for each piece of equipment that you have in your tool shed. Bare units can commonly be found in kits that contain a variety of equipment and then minimize the number of batteries you may need and can also save some valuable space in your tool shed.

On the other hand, if you don’t have a preferred brand or it is the first one, you need to buy a battery and a charger to start with.

How long does a fully charged battery last?

Batteries come in different sizes, and the larger the battery, the longer it lasts when fully charged. Some brands, such as Ryobi, offer batteries that are different and can significantly extend the runtime of your strimmer.

Buying original batteries also influences the quality of the battery, and the reliability may also differ. Overcharging batteries are also a common mistake most people make. Overcharging a battery can shorten the life expectancy of a battery and would cause technical problems to occur.

Rechargeable batteries are not meant to last forever, and it is vital to realize that if your battery starts showing signs of malfunction, instead buy a new one then run the risk of the old one leaking or causing problems.

Which strimmer is the best one to buy?

Each of these strimmers serves a different purpose. The best approach would be to consider what your needs are and how you might be using the strimmer.

  • Do you need to do trimming and edging?
  • How large is your garden?
  • Do you prefer cordless or cable?
  • Are you using it regularly?
  • What is your budget?

Once you’ve considered these questions, you can look at the options and make the necessary decision. When buying a strimmer, make sure it suits your needs, and it can do the job that much easier.


Cordless strimmers have made a big difference, and you can use them everywhere in the garden. Whether you have a large lawn that urgently needs some attention or a small patch that you want to maintain, cordless strimmers make the job much more comfortable. The best cordless strimmer is the strimmer that meets your needs, and of all the cordless strimmers we’ve looked at, the Terratek meets mine.

This strimmer includes batteries and doesn’t require me to buy extra batteries or chargers. It has all the features that I may need and it is flexible enough if my needs change.
