The automatic power-off protection mechanism of HUAWEI power banks

HUAWEI power banks provide an automatic power-off protection mechanism.

1. Our power banks provide 12 layers of protection: charge temperature protection, cell overcharge protection, charge overcurrent protection, discharge temperature protection, cell overdischarge protection, discharge overcurrent protection, battery short-circuit protection, charge overvoltage protection, charge undervoltage protection, output overcurrent protection, output overvoltage protection, and output short-circuit protection. The power bank complies with related national safety standards, EMC standards, and environmental protection standards, and has obtained certification in corresponding areas.
2. When the power bank is charging a phone, it will automatically detect the output current. When the phone is fully charged and the power bank detects that the output current is lower than 80 mA, the power bank will automatically stop charging.
