5. Use Guide

5.1 Charging the Inflator

1. Connect a 5V/2A USB-C charger and cable to the USB-C port on the inflator.
2. Plug the charger into a wall outlet. The display may illuminate to indicate charging.
3. Charge fully before first use. Recharge when the battery indicator is low.

5.2 Selecting the Correct Adapter and Attaching the Hose

1. Identify the valve type on your item:
   • Schrader Valve: Standard on most car and motorcycle tires. Use the main nozzle directly.
   • Presta Valve: Common on bicycles. Screw the Presta valve adapter onto the valve first, then attach the inflator nozzle.
   • Needle Valve: For sports balls and inflatables. Attach the needle valve adapter to the hose.
2. Screw the air hose firmly onto the inflator's output port.
3. Attach the appropriate adapter to the other end of the hose if needed.

5.3 Setting the Target Pressure

1. Press the Power button to turn on the device.
2. Press the Function (MODE) button to select the appropriate preset:
   • Car: Default target ~36 PSI.
   • Motorcycle: Default target ~36 PSI.
   • Bicycle: Default target ~65 PSI.
   • Ball: Default target ~8 PSI.
   • Custom (C): Allows manual pressure setting.
3. In Custom Mode, use the + and - buttons to set your desired target pressure.
4. Press the Unit (U) button to select your preferred pressure unit (PSI, BAR, KPA, KG/CM²).

5.4 Inflating a Tire

1. Remove the valve cap from the tire.
2. Firmly press the inflator nozzle (or adapter) onto the tire valve. Ensure it is seated straight to prevent air leaks.
3. The digital screen will show the current tire pressure.
4. Press and hold the Power/Start button to begin inflation.
5. The inflator will run and automatically stop when the target pressure is reached.
6. Check the pressure on the display. If needed, you can repeat the process to add more air.
7. Disconnect the nozzle from the valve and replace the valve cap.

Tip: For more accurate reading, inflate in short bursts and check the pressure periodically, especially for small-volume tires like bicycles.

5.5 Using the LED Light

Press the LED button on the top of the unit to cycle through the modes: Constant Light → Flashing → SOS → Off. Useful for illuminating the tire valve in low-light conditions.

5.6 Using as a Power Bank

Connect a USB cable from the inflator's USB-A output port to your device (e.g., smartphone) to provide emergency power. Ensure the inflator has sufficient battery charge.

6. Safety and Maintenance

• Read all instructions before use.
• Do not operate the inflator continuously for more than 10 minutes. Allow it to cool down between uses to prevent overheating.
• Keep the air vents on the inflator clear of obstructions.
• Do not use the inflator to inflate any item beyond its maximum recommended pressure.
• Store the inflator and accessories in a cool, dry place.
• Use the included anti-scratch silicone covers on the inflator body to prevent damage.
• Check the hose and connectors for damage before each use.
• When using the 12V car socket, ensure the vehicle is in a well-ventilated area and the engine is running.
