The amazing user reports behind WORX products have been a feature of this product. The lightweight trimmer that is cordless, that gets the job done and without much complaint. What can be seen in this product is that it lasts enough time to get the job done. It is a trimmer, edger and a mini-mower (this is what the wheels are for). The mini-mower function helps for cutting around detailed areas with ease. The battery is 32v lithium-ion which helps with faster charging times, more battery capacity and no slow loss of power. Which means the battery lasts longer and holds charge better. It takes 3 hours to charge which is longer than some other products but it ensures you get good trimming time. It is an automatic single line feed to save time bumping as you go. The handle has different locking adjustments for different levels of comfort. All round it’s the trimmer that’s easy to use, lasts long and will get the job done with ease.

How to Choose a Battery Powered Cordless Grass String Trimmer

Cordless battery powered sting trimmers are a popular choice for their quiet operation, low carbon emissions ease of use and negating the need to fill with gas plus more. What is it that you need to look out for when choosing the one for your needs?

Battery & Power

Usual battery runtime for a cordless grass strimmer is between 40 to 50 minutes. Depending on the type of battery (lithium-ion being most preferred for its fast charging, long lasting and long life cycle features), will depend on what usage time and power you get. Other things to look out for are the volts and amps so you can tell how powerful the trimmer might be.


There aren't many brands that make battery powered grass trimmers which makes it quite easy to make a decision. There are some more reputable and supportive brands than others. Researching the brand before purchase could be a good idea.


If you want a trimmer to last very long then battery powered might not be for you. Decide what your usage needs are and match the features to this. For example, some trimmers double up as edgers or have extending handles. What features do you need to get the job done?

Automatic or Manual Line Feed

When feeding the line while trimming do you want it to be automatic or manual? Manual is usually the stop and bump method and automatic there is no need. There is also trimmers with dual capability. Some people will prefer automatic but some complain it can get awkward when enough line doesn't feed. Be aware of this.

Size, Ergonomics & Weight

As you will be using the trimmer for lengthy periods of time you comfort is important . If the trimmer doesn't have a comfort grip handle will your hands suffer? Or if it is heavy, will you be able to carry it for the amount of time you need?
