How to self-check if the rechargeable battery shows power but cannot charge?

Replace the charging cable / Clean the charging port/ Switch device test: Try to charge other phones/ Check the temperature(>40℃ overheating)

What should I check if the charging is frequently interrupted (disconnected after charging for a while)?

Make sure the connection is solid: check whether the charging cable is plugged tightly with the device interface;

Why does the actual charge count not reach the claimed “5000mAh” power?

Due to the difference in voltage conversion loss, wire resistance, and equipment power consumption, the actual output is about 60-70% (industry standard).

Still have questions？

If you still can't charge after completing the above steps/the charger has obvious physical damage (such as deformed interface, cracked shell), please let us know.
