Now, here’s a totally rad, totally green idea: a rechargeable AA battery that plugs into your USB port. That means no fumbling with battery chargers, no worrying about where to find an outlet, and most importantly, no used batteries to throw out.
The batteries get a 90% recharge in under five hours, and can be reused hundreds of times. They come in a two pack, and because of their size, easily fit into most USB situations. Honestly, I really couldn’t think of the right word to use there, but I think “situation” is closest.
