Charging your gadgets on the move not only lets you avail the green energy, but also shows how keen you are on reducing your carbon footprint. The Keystone Eco Tag lets you do the same a bit differently. Having an inscribable writing space to put your name in there, the device is tagged to your luggage. Moreover, a built-in solar charger with a USB charging port recharges a pair of AAA batteries or other gadgets.

On a sunny day, your gadget won’t take more than four hours to recharge fully. Even if the sun does not shine at its best, this charger charges your device in eight hours. Well, you need to wait until February 2010 to avail it for $35 a pop.
