Panasonic’s Emergency Flashlight can use a combination of AAA, AA, C or D-sized batteries to help you through emergencies or to supply light for an impromptu backyard session of beer pong.
To keep the flashlight’s cost low, Panasonic isn’t making it possible to use all of the batteries at the same time, instead allowing you to use the flashlight to house multiple batteries and choosing which ones you’d like to use. Even though we’d like to see the flashlight use every battery possible all at once, Panasonic is promising 86 hours of use when all battery slots are filled.
