Issue:

Unable to charge the speaker with the charger after the power is used up.

Cause:

The speaker has not been used for a period of time.

The USB port on the speaker or the charging port of the cable is dirty or stained.

Solution:

If the speaker has not been used for a long period of time, it is recommended that you insert the charging cable, then wait until the indicator lights up red before powering it on. Charge the speaker every three months if it is not being used for a long period of time.

If the USB port on the speaker or the charging port of the cable is dirty or stained, clean them using alcohol (equal or higher than 99.5%).

If the issue persists, check whether the charging cable and charger work normally. It is recommended that you use a Huawei 5 V charger.

Note: If the issue persists, escalate it to L2, L3, technical support, and R&D engineers.
