I Took an 8 hour trip and used the 4g connection the whole trip. When I noticed the battery at 18% I tried to charge it using a USB charger that i used for my old iPad 2. It slowed the drain and I was able to continue using it until reaching my destination. I closed all apps that I wasn't using and decreased the brightness. By the end of the trip, the battery was at 6%.
On my return trip of 8 hours, I started out at 100%, kept it charging, and the battery only drained to 48%.
Are there any car chargers that work for the iPad 3?
