Compact BP26 is the lightest, smallest, easiest Weego way to keep your smartphone charged. This plug-and-play battery backup is easy to use. Under 3 oz. and about the size of a pack of gum, it slips in your pocket or purse for the next boost. Simply power up your phone with the long 3.3' Weego micro USB cord or use your own cord (required for Apple device users) to get up to 1-1/2 times extra charge. Charge two devices at once. Samsung lithium-ion battery (2600 mAh) offers more than 500 full charge cycles (3 hours for a full charge). For safe, controlled operation, built-in circuitry protection includes over-voltage protection, over-current safety circuitry and short-circuit protection. Heavy-duty, quality materials and components allow years of durability. Design also includes auto on/off operation, two LED indicator lights and one USB Port. Comfortable, ergonomic shape features a black, soft-touch finish.
