I got to use a few things from my vehicle EDC tonight when the power went out due to the small tornado that touched down about 1/4 mi from my house. I plugged a flourescent bulb into my Campbell-Hausfeld "Power Pal", a portable jump starter/air compressor/DC inverter, and also my crank radio. That bulb lit up an entire room, but we ended up using some oil lanterns for the ambiance.

My wife got to use her Streanlight Key Mate flashlight on her keychain. I was a hero for buying it for her.
