Kobalt 40-Volt Max 13-in Straight Cordless String Trimmer Review

Kobalt 40 Volt cordless string trimmer uses 0.080” trimmer line has adjustable cutting swath from 11 to 13 inches – smaller cutting swath improves battery life but larger cutting swath allows you to cut larger area. It also has two speed modes: 6,800 and 7,800 RPM respectively – you will experience longer battery life using 6,800 RPM but the performance will be better with 7,800 RPM mode.

So how well does it perform? Considering it can do 7,800 RPM you would expect it to be a monster but in reality it’s not. It does perform simple jobs like cutting lawn well but it will struggle with more demanding ones like trimming overgrowth. Overall performance is mediocre and for some it might be good enough, but others will notice the lack of trimming performance.


Dual line auto feed system

Dual line auto feed system works perfectly – you don’t have to do any bumping to feed the line.
