A manufacturer, or atleast what we think they are called HMB-Tec has come up with a gadget.
As they describe it from HMB-Tec, “Put an iPocketFan In Your Pocket. The “Summer Hit of 2010″. Hot days happen. Be cool with the iPocketFan, a pleasant, fresh breeze from the iPhone. Use our little mini-fan for office, club, holiday, car, beach, events, whenever it’s hot. Simply plug into the headphone jack, run the iPocketFan App from the App Store, and enjoy feeling fresh.” – o k a y!
Well the whole idea is that you plug in this fan into the iphone and a custom app is used to turn it on or off as desired.
HMB-Tec has also listed its specifications, which include no battery required, a max of 10mA current consumption, Ipocket Fan App in the App Store and that the device is powered by the head phone jack. Priced at about 20 euros I am not sure if its worth draining your iphone battery!
HMB-Tec is a German based company that features manufacturing iphone accessories and also its apps to run them. Other devices they make that are similar are a heart monitor, thermometer, stethoscope (interesting one), breath controller etc., and these cost between $20 to $90.
Sure you might be spending way too much to have overloaded the battery and to have used it a little too much!
