Despite being relatively new to the industry, Gtech has quickly become one of the top-selling appliance manufacturers in the UK.
Known for their home and garden appliances, Gtech’s products are known for their quality performance and affordable prices, which is exactly what to expect from their impressive ST20 cordless grass trimer. The new 2.0 lawnmower from Gtech is now a firm favourite with many gardeners and the Gtech hedge trimmer is not far behind in popularity.
Like all Gtech products, the ST20 is British made and comes with a cordless design. The cordless feature is one of the best aspects of the ST20, allowing users to trim any part of their lawn without having to grab an extension cord or worry about damaging the cable.
This is especially helpful in large gardens where you end up spending an age just trying to find an extension cord long enough to reach the hard spots!
Of course, being cordless does limit the run time of the ST20 compared to a corded model, but the runtime is more 
than enough for most maintenance tasks throughout the garden. One a single battery charge, the ST20 offers about 30 minutes of run time, which is typically enough to trim borders and such in most average size gardens.
Plus, the cordless design doesn’t impact the power of the ST20. An internal 18V motor offers lots of cutting power, taking out lengthy grass around the edges of lawns without any hassle. When combined with the cordless design, the ST20 makes edging your lawn the easiest it has ever been.
Should the 30-minute runtime not suffice, a good option is to purchase a second battery to interchange while the other charges. In fact, the ST20 is compatible with the same battery that powers their renowned HT20 trimmer, so if you already have this device then you are in luck!
If not, it’s still worth buying a second battery should you have quite a lot of edging and lawn maintenance in mind. Again, 30 minutes is more than enough for most average UK gardens, but those on the larger side may want to consider a second battery to double the run time.
After all, once the battery of the ST20 dies, it takes roughly four hours to completely recharge! So, always make sure you recharge after every use, as the last thing you need is for it to run out of power mid-task. Or you can buy a second battery and always have one on standby should you not want to take any risks.
It’s worth noting that the battery the ST20 takes is a lithium-ion battery. These are the best on the market, boasting fast recharge times compared to any other battery, while offering the most charge possible for the power needed.
So, if you’ve used cordless tools in the past and feel the batteries weren’t up to scratch, don’t be put off by the ST20, as it uses the best battery technology currently available!
