if I can't connect to the network. in, but I'm in real heat. I bought three of these fans with USB connection for battery operation at work. All three failed. One broke after about an hour of use.

(However, the raccoons around our coolers outside of our tent didn't make sleeping any easier, ha!) The batteries lasted two full nights right in the tent, plus two nights in the cabin.
