Should I get a corded electric chainsaw for occasional backyard use?

Yes, if you have an outlet within 100 feet. Corded is simpler, cheaper, and more reliable than battery saws for rare pruning or firewood-cutting sessions near the house. Corded saws also last longer and outperform comparably priced battery models. Just buy a 50- or 100-foot outdoor extension cord (14 gauge or thicker).
