I use a Hyperjuce external battery in my backpack, so whenever I store my MBA in there it gets charged on the move. Or I use it outing the woods connected to that battery - up to 26 hour independence from a power socket with a 150Wh external battery. Not cheap, but it's worth it.

I bought a hyperjuice off this sites marketplace. One that came with the magsafe connector. It turned out to be defective and was repaired free by Hyperjuice. It now works perfectly to charge my MBA and iPad 3.
Good, albiet expensive products AND SERVICE. I also like the DIY thread above.
