Never be "caught in the dark" looking for batteries.   The UST Jolt EDC keychain flashlight recharges on any USB port so you never have to worry about batteries. Features flash mode for signaling and going to raves.  Maybe not so much.  But will definitely flash for whatever reason.  Its also small enough to be out of the way until you need it. IPX4 water-resistant standard. IPX4 basically means it will withstand a splash of water from any direction for 5 minutes.
