Are Mobile Phone charger cable safe
Mobile phone electric shock of 5 elements: 1, the charger will lead to leakage of dangerous voltage power supply 5V to the mobile phone terminal; 2, mobile phone metal coating or metal, metal edge and is connected to the ground; 3, the human body touches the metal edge, and other parts of the body and the ground, on the formation of the circuit; 4. Home electric leakage protector failure, or not at all; 5, the risk of electric shock, near unmanned rescue and timely power-off. Does the wet hand phone really cause an electric shock when charging? Normally, there should be no problem. In accordance with 3C standard charger for the wet experiment, moist environment 93%, then immediately pressure experiment, the input end of the charger output end and the input end of high voltage test of 3000V shell, thus ensuring isolation between primary and secondary, high voltage output terminal will not get, so it is safe.
