Well, I have a 12v 5ah @ 20 hrs Sealed Pure Lead battery hooked up to a DC Aux socket. In the socket, I have a USB car charger.
I am going to be charging my iPhone 6 from it.
The iPhone requires 5v and 1 amp. I have a total of 5 ah so would that give me 5 hours of charging. 5ah/1amp=5
It does notseem right to me so I converted to watt hours.
12v x 5ah =60 watt hours for the battery and the iPhone uses 5 watts to charge.
60 watt hours / 5 watt = 12 hours of charging?
Would anyone be able to help me out with the math on this one?
Thanks!
