12volt iPad charger.

Hi All,

I am after a 12volt hard wired charger for a iPad, not one to plug into a cig lighter. The issue with iPad is that it requires reference voltage on D+ and D- of the USB socket (D+ = 2.8 V and D− = 2.0 V) to tell the iPad that it can charge at the high current. I have tried Jaycar and Baintech, both rated at 2.1A but they only charge iPad at 1amp.

Thanks, Kevin
