If you must know what is in there...:)
Ratings are from 750 ma to 1.5 amp. See I had to look it up. Keeping me honest, nice work. And if you must run more power you can get 11 amps from this one.

For a small fee of course. In the world of IC power costs go up fast with current. But, for most things we might want to run... and the costs I would stick to the Radio Shack part.
