< br >
The type C charging port will be exposed,
Plug the type C port of the earphone into the type C port of the phone\/tablet \/PC to charge.
The method is as follows.
1, choose the right charger. Generally, Bluetooth headsets have a dedicated charger, if there is no dedicated charger, you can find the charging interface (some are thin and round holes, some are MiniUSB universal interface) the same, and rated output power of the same charger to use.
2, when charging, you should plug in all, not only more than half, so that the machine will be damaged for a long time. When inserting and removing the charging plug, it should be light, otherwise it will cause the plug to loose over a long time.
3. If the Bluetooth headset is plugged into the base or charging box, it will take longer to charge than the Bluetooth headset directly after charging. The charging method is the same as charging the headset directly, and you can align the charging cable with the hole in the base and plug it in.
4. After charging, the red indicator lights up, indicating that it is charging. If the charging is complete, the indicator will turn blue or green, and the charger can be removed.
5, when charging the Bluetooth headset, try not to use the headset again to avoid accidental damage.
