Portapower!

This was something I made so I could have enough AC power to run a microwave and TV when I didn't have access to a conventional outlet.

It consisted of a marine battery box with an Interstate Optima Spiral Cell Battery. On the outside I had a 15 volt meter on a push button, two 12 volt power sockets, 3 pair of banana binding posts, and a 1500watt Vector AC Power invertor.
