Meet the Geek Aire: a power bank fan that you can use in handheld mode or your desk to cool down or simply charge your smartphone. It comes with 5 speed settings and uses a brushless DC motor to move air at speed up to 27 ft/s. The fan can run up to 9 hours on the power bank.
The kit consists of a fan, USB capable, hand strap, and charging dock stand. It has 6 aerodynamic blades and doesn’t make a whole lot of noise. You can order yours for under $20 at this time.
