Eton Boost Turbine
It is exactly what it looks like, with a twist. The Eton Boost Turbine ($60) allows you to turn a hand turbine to generate power which in itself is pretty cool. But wait there is more. The Eton Boost Turbine also has a 2000mAH lithium ion battery to store the energy, a strong aluminum body (not plastic), a charge indicator, and a USB port for transferring the power.
