The white square under the fan looks to me like Peltier diode stack ........ the type used in portable caravan hot/cold boxes .... they are very inefficient and this unit needs some sort of USB connecting power supply to drive it ..... probably a Lithium ion power pack ......
........ amazing how some manufacturers can jump on a market in such a short time!
...... it's probably useless!
