2, overload protection
USB specification of the current overload protection requirements must not exceed 5A. Metallic AUTOMATIVE BATTERY CHARGER overload protection is required because the output current is too large and exceed their normal output value, the charger component life will be shortened or because of overheating lead to damage or even burn. Therefore, the metal used in the AUTOMATIVE BATTERY CHARGER must have overload protection measures.
3, short circuit protection
Short circuit protection is also necessary, because in the event of a short circuit lightly hold back the cigarette lighter insurance, heavy fire burns.
