Key Features
- Powerful Dual-Stage Inflation: The first stage provides maximum speed at 430 L/min, while the second stage delivers maximum pressure at 120 L/min. This allows for rapid inflation, such as a 320 cm SUP to 15 PSI in 5 minutes or 20 PSI in 7 minutes.
- Smart Inflate Function & Auto Shut-Off: Set your desired pressure up to 20 PSI. The pump will automatically stop once the target pressure is reached, preventing over-inflation.
- Deflation Function: Easily deflate your inflatables for compact storage and transport.
- Precise Digital Display & Cooling System: An LED digital display shows real-time pressure and allows for monitoring. The digital differential barometer ensures an accuracy of ±0.2 PSI. An integrated cooling system prevents overheating during continuous operation.
- Type-C Input & Fast Charging: Supports Type-C for quick recharging. A full charge takes approximately 2.5 hours.
- Versatile Nozzle Set: Includes 7 nozzle fittings to accommodate a wide range of high-pressure inflatables.
Setup
- Charge the Pump: Before first use, fully charge the pump using the provided Type-C cable and wall charger. The LED display will indicate charging status.
- Attach the Air Hose: Connect one end of the air hose to the 'INFLATE' port on the pump by twisting it clockwise until secure. For deflation, connect to the 'DEFLATE' port.
- Select and Attach Nozzle: Choose the appropriate nozzle fitting for your inflatable's valve. Attach it firmly to the other end of the air hose.
- Connect to Inflatable: Insert the nozzle into the valve of your inflatable. Ensure a snug fit to prevent air leakage.
Operating Instructions
Power On/Off
- To Power On: Press the power button (⏻) once. The digital display will illuminate.
- To Power Off: Press and hold the power button (⏻) for a few seconds until the display turns off. The pump will also auto-shut off after a period of inactivity.
Setting Desired Pressure (PSI)
- After powering on, use the '+' and '-' buttons to adjust the target pressure. The display shows the current setting.
- The maximum pressure is 20 PSI. Refer to your inflatable's recommended pressure.
- Long press the 'Unit Switch' button (S) to switch between LOW, HIGH, and AUTO modes, which correspond to different inflation speeds and pressure stages.
Inflation Process
- Ensure the hose is connected to the 'INFLATE' port and the correct nozzle is attached to your inflatable.
- Set the desired pressure using the '+' and '-' buttons.
- Press the start button (usually the power button or a dedicated start button, refer to pump interface) to begin inflation.
- The pump will automatically switch from the high-speed first stage to the high-pressure second stage as the inflatable fills.
- The pump will automatically shut off once the set pressure is reached.

Deflation Process
- Disconnect the hose from the 'INFLATE' port and connect it to the 'DEFLATE' port on the pump.
- Attach the appropriate nozzle to your inflatable's valve.
- Press the start button to begin deflation. The pump will actively extract air from the inflatable.
- Monitor the deflation process and turn off the pump once the inflatable is sufficiently deflated for packing.

Charging
The TOPUMP TPS300 features a built-in rechargeable battery. To charge:
- Connect the provided Type-C charging cable to the pump's charging port.
- Plug the other end of the cable into the wall charger and then into a standard electrical outlet.
- A full charge typically takes 2.5 hours. The battery indicator on the digital display will show the charging progress.
- The pump can inflate multiple paddle boards on a single charge (e.g., up to 7 SUPs at 12 PSI / 10.6 ft).

Maintenance
- Cleaning: Wipe the pump exterior with a soft, dry cloth. Do not use harsh chemicals or immerse the unit in water.
- Storage: Store the pump and accessories in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the hose and nozzles are clean and dry before storage.
- Battery Care: For optimal battery life, charge the pump fully before long-term storage and recharge every 3-6 months if not in use.
- Cooling System: The pump has a built-in cooling system. Ensure the air vents are not obstructed during operation to maintain proper airflow and prevent overheating.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | Low battery; Power button not pressed correctly | Charge the pump; Press and hold the power button for 2-3 seconds |
| Slow inflation or no inflation | Hose/nozzle not securely attached; Inflatable valve is leaking | Ensure all connections are tight; Check inflatable valve for proper sealing |
| Pump overheats and shuts off | Continuous operation for too long; Obstructed air vents | Allow the pump to cool down; Ensure air vents are clear |
| Inaccurate pressure reading | Sensor issue; Extreme temperature changes | Ensure pump is used within recommended temperature range; Contact support if issue persists |
