“My cell phone is out of juice!” This brings much inconvenience. You may have missed important calls and messages. U-CHARGER is a mini device for power transmission, just like a communicating vessel. Insert it into data interface and you can always carry it easily. It can also connect to the cable through magnet adsorption. If you need power supplement, it can send signals to a nearby device (like smartphone, tablet PC, laptop or camera) for help via radio waves. If there is a match via the app, the donor can share a portion of power with you and your battery will be in quick charging mode. This design can well solve your pressing need.
