Current

• When the current increase in the exception, Power Bank immediately start the buffer voltage function, providing a steady-state voltage at any time. Avoid charging the device or damage.

Short circuit protection

• When there is a short circuit occur in the external device, Power Bank starts the protection function, Shuts down the power supply and avoids damage from the short circuit.

Overheating protection

• When Power Bank runs long in high temperatures (exceeding 60 degrees), Power Bank will not be dangerous due to high temperatures.

Over-discharge protection

• When the Power Bank discharge reached a critical point, the circuit automatically starts the protection function and stops the discharge.

Overload protection

• Long 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.

Overvoltage protection

• Long 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.
