That "power" thing was a pun (batteries and all), right?

EDIT: Lithium batteries are popular for many things (especially cell phones) because they have a great power-to-weight ratio, so that they can go a long time between charges (when used in 100% charge "consumer mode"), while remaining light in wieght and small in size. These lithium battery properties also made tiny remote control flying toys possible (and popular). In fact, I have one of these great little radio-control quad copters (and it comes with a spare battery and extra blades, and less than $45USD including shipping):
