Solar accumulator charging devices for mobile telephones charge up accumulators via solar modules, electronic micro-controllers and load-protection circuits

摘要

Mobile card (1) contains a solar module (2) acting as an accumulator charger. Its thickness and dimensions equate with a credit card. It can be attached to a mobile telephone (MT) (3) as a folding-flap device to fold outwards and has an electrical connection to the MT via a flexible plug-in device (4).
