But the G4air is the most economical solution.
The problem with the cheaper ones is that they won't charge your battery for you. So if you get on board with it drained, you won't be able to charge it up,
which could be important if you need to be able to use it as soon as you get
out of your seat.
It was more expensive, but I dropped the $$$ on the Apple Auto/Air adapter(Made by Lind) and have been quite happy. It comes with both an Empower plug and a cigarette lighter adapter which themselves plug into a
small brick so you can charge your batteries while you have it plugged in.
Lind currently has this for $79.99 on their website
