The Inner Workings
In Action
Justed used an /////Alpine faceplate case as a host.
Uses 4 AA rechargeables.
Works well for overnights a car shows but it wont charge it all the way.
iPhone charges on 5v and this applies 6v so its a good booster for times of heavy usage without access to an outlet. (Or idling the car.)
The diode keep the iPhone from charging the batteries when the voltage drops below 5v
