Color at will of the customer.Security:1. currentWhen the current increase in the exception, Power Bank immediately start the buffer voltage fuction, provides a steady-state voltage at any time. Avoid charging the device or damage.2. Short circuit protectionWhen there is a short circuit occur in the external device, Power Bank start the protection function, Shut down the power supply and avoid damage from short circuit.3. Overheating protectionWhen Power Bank runs long in high temperatures (exceeding 60 degrees), Power Bank will not be dangerous due to high temperatures.4. over-discharge protectionWhen the Power Bank discharge reached a critical point, the circuit automatically starts the protection function and stops the discharge.5. Overload protectionLong time charge for mobile power or use Power Bank charging for your phone. When the saturation point is reached, the system automatically turns off, avoiding overloading the problem.6. Overvoltage protectionLong time charge for mobile power or use Power Bank charging for the phone, when reaching the saturation point, In order to prevent over voltage, the system automatically shuts down.
