12/28v charging for ipad3
I have an iPad3 that i use in aviation. I had an iPad2 which was stolen. With my old iPad i had a 12/28v cigarette lighter adapter that would keep it charged even when in use. It has a 1A and a 2.1A USB plug. The new iPad will not even charge when in use in the airplane, in the 2.1A connection.
Does anyone know how much power it takes to run a"3", and/or is there a 12/28v charger available, preferably with two connections, so i can charge other stuff as well? Thanks in advance for any help?
