Are cordless string trimmers powerful enough to replace gas?

For residential lots up to roughly an acre, the consensus across reviewers we read is yes, especially on 56V/60V platforms like EGO and Greenworks. Specialist subreddit threads still note that the highest-power cordless trimmers trail commercial gas units on sustained heavy brush and tend to bog down with 0.095-inch line under load. For typical fence-line trimming and edging, however, multiple independent testers report cordless cutting performance comparable to gas.
