Product Features
- Compact and Powerful: Weighing only 2.51 lb (1.14 KG) and measuring 7.16 x 6.45 x 3.62 inches (182 x 164 x 92 mm), this pump is highly portable. It can inflate a 10.6 ft SUP board to 12 PSI in approximately 5 minutes.
- Fast Charging and Durable Battery: Supports QC3.0 fast charging, fully recharging in about 90 minutes. A full charge can inflate three 10.6 ft boards to 12 PSI or two boards to 15 PSI, suitable for multiple uses on a single charge.
- Safe Dual-Stage Inflation & Deflation: Features a first stage for maximum speed (400 L/min) and a second stage for maximum pressure (100 L/min). The pump automatically shuts off once the preset pressure is reached, preventing over-inflation. A deflation function is also included for easy packing.
- Real-time Digital Pressure Display: Equipped with a digital differential barometer, the LED display shows real-time air pressure with an error margin of ±0.2 PSI, allowing for accurate monitoring.
- Versatile Nozzle Set: Comes with 7 different gas nozzles, making it compatible with a wide range of inflatables including paddle boards, surfing kites, tents, air mattresses, inflatable boats, and beach balls.

Setup
- Charge the Pump: Before first use, fully charge the pump using the provided Type-C charging cable. Connect the cable to the pump's Type-C port and a compatible QC3.0 fast charger (not included). The LED display will indicate charging status. A full charge takes approximately 90 minutes.
- Attach the Hose: Connect one end of the flexible air hose to the inflation port (usually marked "INFLATE" or with an arrow pointing out) on the pump. Ensure it is securely twisted into place.
- Select the Correct Nozzle: Choose the appropriate air nozzle for your inflatable item (e.g., SUP, kite, mattress). Attach the selected nozzle to the other end of the flexible air hose.

Operating Instructions
Inflation:
- Connect to Inflatable: Insert the attached nozzle firmly into the valve of your inflatable item.
- Set Desired Pressure: Turn on the pump. Use the + and - buttons on the digital display to set your desired pressure (in PSI). The maximum pressure is 20 PSI.
- Start Inflation: Press the power button to begin inflation. The pump will operate in two stages: a high-speed stage (400 L/min) followed by a high-pressure stage (100 L/min).
- Automatic Shut-off: The pump will automatically stop once the preset pressure is reached.
- Disconnect: Once inflation is complete, disconnect the nozzle from the inflatable valve and the hose from the pump.

Deflation:
- Connect for Deflation: Connect the flexible air hose to the deflation port (usually marked "DEFLATE" or with an arrow pointing in) on the pump. Attach the appropriate nozzle to the other end of the hose and insert it into the inflatable's valve.
- Start Deflation: Press the deflation button (if separate, or follow manual's specific instruction for deflation mode). The pump will begin to extract air from the inflatable.
- Complete Deflation: Allow the pump to run until the inflatable is sufficiently deflated for packing.

Maintenance
- Cleaning: Wipe the pump exterior 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. 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 it every 3-6 months if not in use.
- Nozzle Maintenance: Keep nozzles clean and free of debris. Check rubber gaskets for wear and tear and replace if necessary to ensure a tight seal.
