Abstract
This invention provides a wireless input device, including a primary battery set, a backup battery, an electricity generating device, an energy-storage/charging device, and a switching device. The primary battery set provides electricity to the wireless input device. The backup battery provides electricity to the wireless input device when the primary battery set does not have sufficient electricity. The electricity generating device generates electricity in response to clicking/pressing operations to the wireless input device. The energy-storage/charging device is coupled to the backup battery and the electricity generating device. The energy-storage/charging device stores the electricity generated by the electricity generating device and charges the backup battery when the stored electricity has reached a predetermined volume. The switching device is coupled to the primary battery set and the backup battery. The switching device selects the primary battery set or the backup battery to provide electricity to the wireless input device.
