I. Charging Environment Safety

Use only in dry, well-ventilated, and room-temperature environments. Avoid charging in damp areas such as bathrooms or near water pools to prevent water vapor from entering the interface and causing short circuits or electric shocks.

Keep away from open flames, high-temperature heat sources (such as radiators and induction cookers), and flammable and explosive materials. Maintain sufficient heat dissipation space for the charging cable and charger during charging; do not cover them with quilts or clothing.

Use compliant power interfaces (such as original chargers and regular brand USB sockets). Avoid using inferior power strips, high-power adapters, or charging devices with mismatched voltages. The output voltage is recommended to match the rated charging voltage of the shaver (usually 5V).

II. Cable and Interface Maintenance

Inspect the cable appearance regularly. If the insulation layer is damaged, cracked, or exposes copper wires, or if the interface is loose, oxidized, rusted, or has poor contact, stop using it immediately and replace it with an original or certified cable of the same specification.

Avoid excessive bending or pulling of the cable. Do not twist the cable or place heavy objects on it during charging. When storing, coil it with an appropriate radius (recommended no less than 5cm) to prevent internal wire breakage.

Keep the USB interface and shaver charging port clean and dry. If there is dust, hair, or other debris, gently clean it with a dry soft brush. Do not wipe with metal tools or damp items.

III. Usage and Operation Specifications

Ensure the cable is fully inserted into the interface during charging to avoid local overheating caused by loose connections. Do not repeatedly plug and unplug the cable during charging to reduce interface wear.

Do not privately modify, cut the cable, or replace mismatched interfaces. Prohibit using the charging cable for high-power devices other than the shaver to prevent overloading and burning the cable.

Unplug the cable promptly after charging is complete. When not in use for a long time, store the cable separately from the shaver to avoid potential risks under continuous power-on conditions.

IV. Handling of Special Situations

If abnormal heating, strange odors, or smoke is detected from the cable or interface during charging, immediately disconnect the power supply, stop using it, and contact the brand after-sales service for inspection.

If the cable accidentally comes into contact with liquid, first cut off the power supply. Do not reuse until the cable and interface are completely dry and confirmed undamaged; replace it directly if water ingress is severe.

Children must use the product under adult supervision to avoid safety hazards caused by biting or pulling the cable.
