Not my work found it on google image but me-thought it was cool.

My old 90's r/c car charger is about the size of a cinder block and state of the art then, its enormous for todays chargers that do it faster and smarter. Looks at the usb charger, its awesome.

Smarter:
Theres a post @ ft discussion about temperature control, you can wire the usb up to be an intelligent smart charger. It made me do some research and thats when I found this, I never would have thought it, its so cool lol.
With a few skills most things are inexpensive, its the reading to gain them part that sucks. Woot internet...
