The landscape for cordless lawn trimmers changed dramatically when powerful battery technology and multi-function features entered the picture. Having tested all these options, I can say some stand out for their versatility and performance. The WORX 20V Cordless String Trimmer & Edger, 12”, WG163, impressed me with its quick conversion from trimmer to edger and the easy-angle head. Plus, the adjustable spacer guard and rubberized wheels made straight lines on tricky terrain effortless.
Compared to others, it offers a solid balance of power, lightweight design, and innovative features like instant line feed. While the MZK 20V 12” Cordless String Trimmer is cheaper and has a high RPM motor, it lacks the multi-angle setup and adjustable handle of the WORX. The WORX WG170 is feature-rich but pricier and more bulky, and some others don’t match its combination of accessories and ease of use. After thorough testing, I recommend the WORX 20V Cordless String Trimmer & Edger for users who want reliability, versatility, and value all in one package, with the added bonus of WORX’s extensive battery compatibility.
Top Recommendation: WORX 20V Cordless String Trimmer & Edger, 12”, WG163

Its lightweight 5.5 lb. build and adjustable spacer guard make it user-friendly, while the dual 20V batteries ensure ample runtime. Its versatility on sloped terrain and cleaner lines due to support wheels set it apart, offering the best balance of power, features, and value.
