I was talking with a friend recently and was reminded of this battery charger idea that I thought I would share with you all. It's got a better than average charge capability, runs on 2 AA batteries (regular or rechargeable), and fits neatly in your pocket. Nothing like some
minty fresh GPSing with your iPhone!
This will take some technical know-how, but if you've never done something like this before, chances are you know someone who can help you if you'd like to give it a go.


I first learned about this neat device
here. The kit as linked above is roughly $20. Enjoy!
