Mini High-Speed Handheld Fan,Portable USB Rechargeable Personal Cooling Fan with Adjustable Speed

1. Instructions for Use

1.1 Charging the Fan

1. Before first use, fully charge the fan using the included USB charging cable.

2. Insert the USB-C (or Micro-USB) end into the fan's charging port, and connect the other end to a compatible power source (such as a computer USB port, power bank, or 5V/1A wall adapter).

3. The indicator light will typically turn red while charging and green (or turn off) when fully charged. A full charge usually takes 1.5–3 hours, depending on the model.

1.2 Operating the Fan

1. Turn On/Off: Press the power button once to turn the fan on. Press and hold the button for 2–3 seconds, or press repeatedly until the fan stops, to turn it off.

2. Adjust Speed: Most models feature multiple speed levels. Press the power button repeatedly to cycle through the speed settings (e.g., Low → Medium → High).

3. Use as a Handheld Fan: Hold the fan by its handle to direct airflow where needed.

4. Angle Adjustment: If the fan head is adjustable, tilt it up or down to change the airflow direction for your comfort.

2. Important Safety & Usage Precautions

• Electrical Safety

  • Only use the included USB cable or a certified replacement cable for charging. Do not use damaged chargers or cables.

  • Do not charge the fan in humid environments (e.g., bathrooms) or expose it to rain, water, or other liquids.

  • Unplug the fan once it is fully charged to avoid overcharging the battery, which can shorten its lifespan.

  • Do not disassemble, puncture, or attempt to modify the built-in battery. This may cause overheating, fire, or injury.

• Usage Safety

  • Keep the fan at least 10 cm away from your face, hair, clothing, or any loose objects while operating to prevent them from being pulled into the fan grille.

  • Do not insert fingers, pens, or other objects into the fan grille while the fan is running.

  • Do not use the fan in environments with high temperatures (above 40°C/104°F) or near heat sources, as this can damage the battery and internal components.

  • Do not use the fan while it is charging.

• Storage & Handling

  • If the fan will not be used for an extended period, charge it to about 50% capacity and store it in a cool, dry place.

  • Do not drop, throw, or subject the fan to strong impact, as this may damage the internal motor, battery, or components.

3. Cleaning, Maintenance & Repair

3.1 Cleaning & Maintenance

1. Cleaning the Grille and Blades:

   • Ensure the fan is turned off and unplugged before cleaning.

   • Use a soft, dry cloth or a small, soft brush to gently wipe dust off the grille and blades.

   • For stubborn dirt, use a slightly damp (not wet) cloth with mild soap. Never submerge the fan in water, as this will damage the motor and battery.

2. Exterior Care:

   • Wipe the handle and body with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners, as they may scratch or discolor the surface.

3. Battery Maintenance:

   • To preserve battery life, avoid letting the fan fully discharge regularly. Charge it when the power level is low.

   • If the fan’s runtime drops significantly after a year or more of use, the battery may have degraded, which is normal for lithium-ion batteries.
