I have a couple of powerful backback blowers (Stihl and Echo - 2 stroke) that will move some air....but you don't always need that. Went looking for a hand held battery unit for my dad about a monrh ago, so my mom could easily use it too, blowing out garage, clearing sidewalk, driveway, etc. Settled on an Echo ($199 from HD) with a 58v battery that's a pretty good blower imo. Like theirs so much I went back later and got me one
