Battery Power bank


This Power bank has a 17500mah battery that is used in RC cars. Its a NiMh battery. Other than this I have step up its voltage from 7.2 volts to 12v to be used in the circuit. I have used a circuit of a cigarette lighter chanrger and then installed a switch and packed it inside a spectacle case. 

The main USP of this charger is that it can be charged within 15 minutes by using socket in your car hence this is technically a portable power bank which does not need an AC input.
