6. Fehlerbehebung
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. Benutzertipps
- Aufladen der Powerbank: The Xiaomi Portable Air Pump supports charging with a power bank, provided the power bank's output meets the Type-C, 5V-2A requirements.
- Automatischer Speicher: 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.
- Abkühlen: If inflating multiple items or for extended periods, allow the pump to cool down between uses to prevent overheating and ensure longevity.
