EcoXPower Bike USB Charging Device

Cleantechnica reports on the EcoXPower, a device added to your bike that provides light as well as charging over an USB-cable. I could run my Kindle on that.

On the other hand, while that does help somewhat with saving energy, this is a very small factor of the total load, as pointed out in David McKay’s book on energy issues (Chapter 11 on Gadgets).

I am still interested in getting such a device. If I can buy it in Japan and get it to work on my bike, I may come back to report about my experience.
