1.21 jigawatts!? Great Scott!

We had a vision here at ThinkGeek. We slipped and hit our head on the sink. It was mostly fuzzy. Actually, it was all fuzzy. There was a definite concussion involved. But after that, we had another vision! It involved carrying around the beloved Flux Capacitor everywhere we go. And so it shall be.

The Back to the Future Flux Capacitor Light Up Keychain shrinks down one of your favorite devices for making time travel possible and lets you hook it right on your keychain. No plutonium needed - this sucker is electrical. Light up your keychain with hottest new invention this side of Hill Valley.
