We just added to our EQ kit the Blackout Buddy by Eton, an emergency LED Blackout flashlight that plugs and recharges straight from your wall socket, Handily, it also performs as a night light, perfect for the home and office. The fold-up prongs plug directly into an electrical socket for a constant charge. ($15.)
Because you just know that when the next big one hits, it's going to be at night.
