Are cordless string trimmers powerful enough to replace gas?

For typical residential trimming and edging, the reviewers we read say yes. Across r/egopowerplus and r/lawncare, owners of higher-voltage 40V and 56V models report performance comparable to small gas trimmers for grass and light-to-medium weeds. The recurring caveat is that battery trimmers deliver duration rather than raw torque, so for thick brush or all-day commercial use, gas still has an edge.
