Review on TriPole Desk Fan Small Table Fan Rechargeable Battery Operated Mini Fan 360 Degree Rotation 5.1 Inch Portable Fan 4 Speed USB Personal Fan For Home Office by Benjamin Michels

It seems to run several hours on low, actually never ran it dead, probably ran for 4 hrs before though and it didn't run out of charge. The low/med/high settings are appropriate, charging via micro-USB works well, build quality seems decent enough. It's funny how sometimes small random purchases like this end up being things you use all the time and really value. It's a good little fan. Of course don't expect it to move massive volumes of air, it's meant to use from 2-3ft away, not from all the way down the hall. But it's small, of course it's not a giant room fan.
