The UST Jolt Mini USB LED Light allows you light your way without using batteries and still manage to be small enough to clip on your keys. The UST Jolt Flashlight/USB is a handy rechargeable light you can take on the go. It recharges in any USB output device such as PCs and USB car adapters. A built-in clip attaches just about anywhere you need extra light, such as a key ring, zipper, or backpack. It can be recharged over 500 times and never needs batteries. It has a bright 25 lumen LED with steady ON and FLASHING modes, with an easy twist on/off switch. Simply plug and recharge at any USB port and a red LED charging indicator lets you know it is charging. It is water- resistant when securely closed and is available in Black or Orange.
