Abstract
A super-capacitor-powered device is quickly recharged from an energy buffer incorporated in a USB cradle or USB dongle. That USB energy buffer itself is slowly refilled while it is connected to a USB port. The super-capacitor can be in parallel to a battery. In one embodiment, a facilitated battery changer is provided. A battery swap is performed with a recharged battery in a charger having two battery slots.
