If you need another mains charger because the old one is broken or you simply want to have a spare charger everywhere so you don't have to carry it with you, then you need this product. Its structure and functionality correspond to the 220 V mains charger provided in the phone's basic package. It has modern charging electronics and a charging LED. After charging the phone's battery, the charger switches to drip charging, thus protecting your battery from overcharging. ATTENTION: The charger can only be used for devices on the compatibility list!
