The SunCharger can be used as a power supply, a replacement battery or a mobile solar charger. It generates energy on the spot for mobile devices like mobile telephones, cameras, GPS devices and MP3 players. The unit meets the criteria of the new EU standard and works independently of an external power supply. High-efficiency silicon cells constantly charge the integrated battery, and the various devices are then supplied with energy via a USB cable. The surface size of the solar cell is increased by opening the slider.
