4. Operating Instructions
4.1 Power On/Off and Display
Press the power button to turn on the device. The micro margin display will show the current pressure and battery level. The display features a high-quality IML process, making it wear-resistant and scratch-resistant.
4.2 Selecting Inflation Mode
The air pump offers multiple preset modes for various scenarios. Use the mode selection button to cycle through them:
- Motorcycle/Electric Bicycle Mode: Default 2.4 bar (Adjustable range: 1.8-3.0 bar)
- Bicycle Mode: Default 45 psi (Adjustable range: 30-120 psi)
- Electric Scooter Mode: Default 50 psi (Adjustable range: 45-60 psi)
- Ball Mode: Default 8 psi (Adjustable range: 4-16 psi)
- Custom Mode: Default 35 psi (Adjustable range: 0.2-10.3 bar / 3-150 psi)
The last preset value in custom mode is automatically memorized for convenience.
4.3 Setting Target Pressure and Inflation
- Connect the appropriate nozzle to the item you wish to inflate.
- The pump will automatically detect the current tire pressure.
- Select the desired mode or adjust the target pressure using the '+' and '-' buttons.
- Press the inflation button to start. The pump will automatically stop once the target pressure is reached, preventing overcharging.
4.4 Emergency Lighting
The air pump includes a self-contained lighting lamp for night use or emergencies. It offers a steady white light mode and an SOS flashing alert mode.
5. Maintenance
- Cleaning: Wipe the exterior of the pump with a soft, dry cloth. Do not use harsh chemicals or immerse the device in water.
- Storage: Store the air 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 completely draining the battery frequently. Charge the device regularly, even if not in use for extended periods.
6. Troubleshooting
6.1 Device is making noise during operation.
The inflatable pump operates by a motor driving a crankshaft to apply pressure. The friction between the piston and cylinder, along with motor noise, is normal and inevitable. The noise level is typically around 80 decibels at a distance of 1 meter.
6.2 How long can the pump inflate on a full charge?
When fully charged and at an ambient temperature of 25 degrees Celsius, the pump can operate continuously without load for approximately 13 minutes. Ambient temperature and load level will affect battery life. For example, it can inflate 8 empty bicycle tires on a full charge.
6.3 Can the pump inflate swimming rings or rubber boats?
The Xiaomi portable air pump is designed for high-pressure items like tires and basketballs. While it can technically inflate low-pressure items like swimming rings and rubber boats, the inflation speed will be very slow, making it unsuitable for these purposes.

8. User Tips
- Power Bank Charging: The Xiaomi Portable Air Pump supports charging with a power bank, provided the power bank's output meets the Type-C, 5V-2A requirements.
- Automatic Memory: In custom mode, the last set pressure value is automatically saved, so you don't need to reset it for repeated tasks.
- High-Pressure Focus: This pump is optimized for high-pressure inflation. For low-pressure items like swimming rings or large inflatable toys, inflation will be very slow and may not be efficient.
- Cool Down: If inflating multiple items or for extended periods, allow the pump to cool down between uses to prevent overheating and ensure longevity.
