Charging and Operation

Charging

Follow these steps for charging:

Please charge the Cleaner with the official standard power adapter of CHASING.
Dry the water on the charging port of the Cleaner before charging.
Align the charger with the anti-misconnection design of the charging port and insert it correctly.
If the power adapter indicator is in red, the charging is in progress; if in green, the charging is completed. After charging, unplug the adapter in time.
Reinstall the rubber plug after charging to prevent water from entering.
Before charging, please use a dust blower to remove any moisture and dust from inside the charging port.

Precautions for charging and storage:

As long-term storage will accelerate self-discharge and passivation of active substances, it is recommended to fully charge and discharge the Cleaner every three months to reduce the negative impact of long-term storage, and then restore its original performance.
The lithium battery of this product is not replaceable, so it should be recycled by a qualified battery recycling station, rather than being discarded in the trash can.
Do not place the device vertically for charging to prevent water from entering the charging port.
Do not charge indoors.
