Features Overview
- Digital Pressure Gauge & Auto Stop: Equipped with a high-definition LED display, this pump provides easy-to-read preset and real-time pressures (MAX 120PSI). It automatically stops when the set pressure is reached, preventing over-inflation.
- Tiny Size & Portable Carry: Weighing only 0.29 pounds (130g) and measuring 2.09 x 1.26 x 3.03 inches, this super compact pump is designed for easy portability, fitting into small bags or pockets.
- Rapid Inflation: With an airflow of 15L/min, it can inflate a 700*25C tire from 0 to 80 PSI in approximately 50 seconds, ensuring quick emergency inflation.
- Durable & Fast Charging: The Type-C USB charging cable allows for a full charge in just 30 minutes. A single charge can inflate at least three 700*25C tires from 0 to 120 PSI.
- 2 Inflation Methods: Supports both Presta and Schrader valves for direct inflation. An included air hose and Presta valve converter simplify the inflation process, freeing your hands.

Operating Instructions
1. Selecting the Correct Valve Adapter
The Tiny Pump supports both Presta and Schrader valves. Identify your tire's valve type:
- For Schrader valves (wider, typically found on mountain bikes and cars), you can connect the pump directly or use the air hose.
- For Presta valves (thinner, typically found on road bikes), use the included Presta valve converter with the air hose.
- For Ball needles, attach the ball needle adapter to the air hose.

2. Connecting to the Tire Valve
Securely attach the appropriate adapter or the pump directly to the tire valve. Ensure a tight seal to prevent air leakage.
3. Setting Desired Pressure
Turn on the pump. Use the '+' and '-' buttons to set your desired tire pressure. The LED display will show the target PSI. You can switch between PSI and BAR units if needed.
4. Starting Inflation
Press the power button to begin inflation. The pump will automatically stop once the preset pressure is reached.

Important Notes:
- When the target air pressure is above 100 PSI, please use the included air hose to prevent air leakage from the nozzle.
- For TPU inner tubes with resin valves, be sure to connect them with an extension air hose, or the valves may melt due to overheating.
Maintenance
- Cleaning: Wipe the pump with a soft, dry 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. Use the provided waterproof bag for protection.
- Battery Care: To prolong battery life, charge the pump regularly, even if not in frequent use. Avoid completely draining the battery before recharging.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | Low battery or no charge. | Charge the pump fully using the USB Type-C cable. |
| Air leakage during inflation. | Valve connection is not secure or incorrect adapter used. | Ensure the adapter is tightly screwed onto the valve. Use the correct adapter for your valve type. For pressures above 100 PSI, use the air hose. |
| Pump stops prematurely. | Preset pressure reached or low battery. | Check the preset pressure. If it's lower than desired, adjust and restart. If battery is low, recharge. |
| Inaccurate pressure reading. | Sensor calibration or external factors. | Ensure the connection is stable. The sensor is accurate to +/- 1 PSI. If persistent, contact customer service. |
