Batteries charge pretty quickly, the power adapter has an LED that is red when charging, and goes green when done. The motor seems to spin sufficiently fast and the power is enough.
Quickly assembled, a thought struck! I pointed the blower at the back of the refriegerator and sent debris out where I could vacuum it! (Perhaps not something Greenworks intended it for, but it worked!)
Outside, it is light enough for my young Grandson and powerful enough to clear my patio of leaves and debris, even shifting a loosly laid, terrazzo tile with its' force! Kudos Greenworks! This is another great tool in my (mostly) outdoor collection!
This is the most powerful blower you can get without going to a backpack unit. It's strong enough that when I am blowing grass clippings I have to barely hold the trigger to get it pushed in and only need half throttle if they get wet. It's trigger allows great control over how hard it blows.
Very happy with leaf blower. Very powerful and the battery lasts longer than what I need to clear my driveway and sidewalks. I already had batteries and charger so all I needed was the blower itself but they included another battery for free.
