Setup
1. Initial Charging
Before first use, fully charge the air compressor. Connect the provided Type-C charging cable to the charging port on the device and the other end to a 5V/3A USB power adapter (not included). The battery indicator on the display will show charging progress. A full charge typically takes approximately 3.5 hours.
2. Attaching the Air Hose
The air hose is stored by being locked into the device. To use, pull the air hose out of its storage slot. This action will automatically power on the device. Connect the appropriate valve adapter (Schrader, Presta, or needle valve) to the end of the air hose, depending on the item you intend to inflate.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is depleted; Air hose not fully pulled out. | Charge the device; Ensure the air hose is fully extended from its slot. |
| Inflation is slow or ineffective. | Low battery; Air hose not securely connected; Incorrect pressure setting. | Recharge the device; Check all connections for leaks; Verify the target pressure. |
| Device stops unexpectedly. | Target pressure reached (auto shut-off); Overheating; Low battery. | This is normal if target pressure is met; Allow device to cool down; Recharge the device. |
| Inaccurate pressure reading. | Loose connection; Sensor error. | Ensure the air hose is tightly connected to the valve; If problem persists, contact support. |
