3. Setup
3.1 Charging the Device
Before first use, fully charge the pump using the provided Type-C cable. Connect the cable to the Type-C port on the pump and a compatible USB power source. The battery indicator on the display will show charging progress.
3.2 Attaching the Taillight Adapter
The pump can be mounted to your bike's seat post using the included taillight adapter. Secure the adapter to the seat post, then slide the pump onto the adapter until it clicks into place. This allows the pump to function as a rear safety light during rides.

4. Operating Instructions
4.1 Power On/Off
To power on the pump, long press the power button. The digital display will activate. To power off, long press the power button again.
4.2 Setting Target Pressure
Once powered on, use the '+' and '-' buttons to adjust the desired PSI (Pounds per Square Inch) on the digital display. The pump features an auto-shutoff function that will stop inflation once the set pressure is reached.
4.3 Inflation Procedures
The pump supports Schrader, Presta, and ball valves. Ensure the correct adapter is installed for your specific item.
4.3.1 Schrader Valve Inflation
- Install the Schrader valve adapter onto the pump's inflation port.
- Firmly press the pump onto the Schrader valve stem of the tire.
- Press the power button to begin inflation. The pump will automatically stop when the set PSI is reached.

4.3.2 Presta Valve Inflation
- Install the Presta valve adapter onto the pump's inflation port.
- Unscrew the Presta valve cap on your tire and slightly open the valve.
- Firmly press the pump onto the Presta valve stem.
- Press the power button to begin inflation. The pump will automatically stop when the set PSI is reached.
4.3.3 Ball Inflation
- Insert the ball needle nozzle into the pump's inflation port.
- Insert the needle into the ball's inflation hole.
- Press the power button to begin inflation. The pump will automatically stop when the set PSI is reached.
4.4 Taillight Functionality
The integrated taillight offers three modes for visibility and safety:
- Steady Mode: Provides continuous illumination.
- Flow Mode: Offers a dynamic, flowing light pattern.
- Flash Mode: Emits a flashing light for maximum attention.
To activate the taillight, long press the light button. Short press the light button to cycle through the modes. Long press again to turn off the taillight.

5. Key Features
- Precision Pressure Control: Real-time tire pressure monitoring on a high-contrast digital display. Automatic shut-off at the target PSI (±1 PSI) prevents over or under-inflation.
- Integrated Taillight: Unique built-in taillight with steady, flowing, and flashing modes for improved visibility and safety during night or low-light conditions. Includes a seat-mount bracket.
- Ultra-Portable Design: Weighs only 4.4 oz (125g), making it easy to carry without bulk.
- Durable Construction: Engineered to withstand 1.2m drops, features IPX4 water resistance, and operates in temperatures from 5°F to 122°F (-15°C to 50°C).
- High Pressure Output: Delivers up to 120 PSI with ±1 PSI precision. Can inflate a 700 x 23C tire (65-100 PSI) in approximately 30 seconds.
- Universal Compatibility: Effortlessly switches between Presta and Schrader valves. Includes a needle nozzle for inflating sports balls.

7. Maintenance
- Cleaning: Wipe the pump with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the pump in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery life, charge the pump regularly, even if not in frequent use. Avoid fully discharging the battery for extended periods.
- Nozzle Care: Ensure all nozzles and adapters are clean and free of debris before and after use to maintain proper sealing and prevent damage.
8. Troubleshooting
- Pump not turning on: Ensure the battery is charged. If fully charged, try a long press on the power button.
- Slow inflation or insufficient pressure: Check that the valve adapter is firmly attached to both the pump and the tire valve. Ensure the tire valve is fully open (for Presta valves).
- Pump gets hot during use: This is normal during extended inflation. Allow the pump to cool down before continued use.
- Inaccurate pressure reading: Ensure the pump is securely connected to the valve. If issues persist, contact customer support.
