The 5 Best Electric String Trimmers of 2018

The 5 Best Electric String Trimmers of 2018

Electric string trimmers are becoming increasingly popular due to their convenience and functionality. However, not all electric string trimmers are the same. Before moving on to the important specifications of the 5 best electric string trimmers of 2018, we will explain some key features of electric string trimmers.

Type - battery-powered electric string trimmers use a rechargeable battery, while corded electric string trimmers plug in to an AC electrical outlet; most corded electric string trimmers do not include a power cord and therefore require you to purchase the power cord separately

Line Diameter - the diameter of the line used to perform the trimming or edging; bigger is not necessarily better

Line Feed - some electric string trimmers require the spool to be bumped to advance the line, while others with auto line feed mechanisms advance or feed the line automatically to eliminate bumping; auto line feed offers convenience at the cost of the control offered by bump mechanisms; also, auto line feed mechanisms may be more prone to malfunction

Max Speed(s) - the maximum speed the electric string trimmer will spin with no load at a given speed setting; some electric string trimmers offer multiple speed settings as indicated in the specifications below by multiple maximum speeds

Battery and Charger Included - some electric string trimmers come with a battery and charger, and others are sold without as the bare tool

Battery Capacity - the capacity of the battery (if provided with the electric string trimmer) in Amp hours (Ah); more is better

Runtime - the total time that the electric string trimmer will operate using the battery included with the unit

Charge Time - the total time required to charge the battery or batteries included with the electric string trimmer

Telescoping Shaft - allows the shaft of the electric string trimmer to be extended to vary the length and accommodate users of different heights

Motor Amperage - the current draw of the electric motor of the electric string trimmer; this is somewhat indicative of the power of the electric motor (e.g., similar to the horsepower of a gasoline engine)

Cutting Diameter (Swath) - the diameter of the circle traced by the outer tip of the line as the spool rotates; when used as an edger, a smaller cutting diameter or cutting swath is preferred as it reduces power draw and also reduces disturbance of the line which results in a straighter and cleaner cut

Wheeled Edger - wheels are provided to allow the electric string trimmer to be rolled along the ground as it performs the edging

Mini Mower - wheels are provided to allow the electric string trimmer to be rolled along the ground as it performs horizontal trimming, thereby acting as a "mower"; the WORX GT 2.0 is the only electric string trimmer to offer this feature

Adjustable Spacer Guard - a feature only offered by the WORX GT 2.0 electric string trimmer that extends across from the safety guard to indicate the outer cutting diameter/swath and reduce accidental damage to flowers and other objects when used as a horizontal trimmer

Weight - the weight of the electric string trimmer itself (not the shipping weight including the box and packaging material as some sites use)
