Great little fan!!

This little guy is so quiet but makes a lot of air move!
we bought it to put on the dash of our 4 door Jeep to
move cold air to the rear. I love the 3 speeds and it is
rechargeable. Very nice fan! Happy with it!

Excellent Power to Size Ratio

Works for an extremely long time on one battery charge, even on the level 3 setting.
Easily cooled my 1200+ cubic feet size room during our super heatwave over the last few weeks here in CA
This is a great little workhorse fan.
