Connect your mobile device to the USB-A output port (5V/2A) on the pump using a compatible USB cable to charge your device.

6. Maintenance

• Cleaning: Wipe the exterior of the pump with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the device is dry before storage.
• Storage: Store the pump and its accessories in the provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Recharge the pump regularly, even if not in use, at least once every 3 months.
• Hose Inspection: Periodically check the high-pressure hose for any signs of wear, cracks, or damage. Replace if necessary.

7. Troubleshooting

• Pump does not turn on:
  • Ensure the battery is charged. Connect to a power source and charge for at least 30 minutes.
  • Press and hold the power button for 2-3 seconds.
• Pump inflates slowly or not at all:
  • Check that the air hose and valve adapter are securely connected and there are no leaks.
  • Ensure the correct inflation mode and target pressure are set.
  • Verify the battery level. A low battery can affect performance.
• Inaccurate pressure reading:
  • Ensure the valve adapter is fully seated on the item's valve.
  • Disconnect and reconnect the pump to reset the reading.
• Pump is noisy during operation:
  • It is normal for the pump to produce a noticeable operating sound during inflation due to the internal motor and compressor. This is not indicative of a fault.
• Overheating protection activated:
  • If the pump becomes too hot during prolonged use, it may automatically shut down. Allow it to cool down for at least 15-20 minutes before resuming operation. The built-in fan aids in heat dissipation.
