I am a fair weather golfer, aren't we all? With global warming on the cusp, golf on the fritz, I try to contain my emotions. This fan helps, alot! Golf carts nowadays have USB plugs, game on! Fits nice in a cart holder, a cup holder, whatever. I have been in a warm restaurant and have trekked to the truck and brought my fan inside. runs off a battery pack, golf cart, or car plug. It's a fan, and so am I.
