Side Bar - electronic stuff

Between us, we have more than 10 devices that have to be charged. We have bike computers, tail lights, phones, MP3 players, a camera... And a bundle of USB cords... Each device has its own connection. 

I have a solar panel on the back rack of my bike with two battery packs. When one battery pack is recharged we put the other one on to recharge. Each battery pack seems to recharge 1 1/2 devices. We also carry an AC charger into places we stop. 

We keep the phones on airplane mode almost all the time, so the batteries last quite a while.
