Depends on the style. An plug-in electric leafblower is constrained to around 2HP max (746W/HP) while drawing 12A from a 15A circuit. A handheld gas one will have a 25cc engine and can probably do 2HP max. But the backpack style gas leafblower that landscaping crews often use will have a 50 or 60cc engine that would put out 3 or 4HP, so will be able to blow more strongly.
