How many amps do I actually need in a corded leaf blower?

For dry leaves on a small to mid-size yard, 7-9 amps (like the BLACK+DECKER LB700 or Sun Joe SBJ597E) is generally enough according to retailer reviewers. For wet leaves, larger debris, or quarter-acre-plus properties, the consensus across r/lawncare threads pushes toward 12-amp units like the WORX WG520 or the BLACK+DECKER BV6000.
