Best Cordless Electric String Trimmers – Top 5 Brands Ranked

This is our official list of the best cordless electric string trimmers on the market today

Highest Reviewed Cordless String Trimmers


The most effective cordless string trimmer will help you complete minor outdoor yard work jobs without having to worry about extension cords, buying gas, or maintaining a carburetor. Keep in mind that a trimmer is better for cutting weeds or grass but not necessarily for cutting down tougher weeds or brush.

Cordless trimmers include either a Ni-Cad battery or a Lithium-Ion battery. Ni-Cad batteries are heavier and less expensive. They also usually drop in power as they lose their charge. On the other hand, Lithium Ion batteries have revolutionized outdoor power tools because they are lightweight and have a long-lasting charge that doesn’t fade as the battery depletes. Keep in mind whether you have other tools that share a similar battery when choosing a trimmer.

Tools with more than one use are a nice addition to a tool collection and many cordless trimmers have the ability to be used as a grass edger simply by turning the pivoting cutting head. The user is able to trim and edge the grass without having to get out another tool. The shaft of the trimmer could be curved, straight or adjustable. A curved shaft is helpful for cutting in tight areas, and has the ability to make the trimmer easier to control. Reaching under obstacles like decks, shrubs and benches might be easier with a straight shaft. The adjustable shaft will allow the user to adjust the working height of the trimmer.
