This product is suitable for supplying power in small-scale electric apparatus charging or direct current power use. Adopt the electronic elements of international high-quality famous-brand enterprises and IC circuit. Handsome in appearance , small , input the voltage range widely (AC 100V-240V ), export the direct current to press steadily, exceed press , ultra warm , overload ,short-circuits owers the pressure the automatic protection function. But according to different demands, choose to output the voltage: DC 4.5V , 5.1V , 5.2V , 6V , 7.5V , 12V. Can development manufacture according to customer s enquiry . Pass UL authentication E253327 .
