4. Power and Charging

4.1 Initial Charge

Before first use, fully charge the internal battery.

1. Connect the provided Type-C charging cable to the inflator's charging port.
2. Connect the other end to a standard USB power adapter (not included) or a computer USB port.
3. The unit's display may illuminate to indicate charging. A full charge typically takes several hours.

4.2 Dual Power Modes

The inflator can operate in two ways:

• Cordless (Battery) Mode: Use the internal rechargeable battery for complete portability.
• 12V DC Car Power Mode: If the battery is low, plug the 3M cigarette lighter cable into your vehicle's 12V outlet (cigarette lighter socket) and into the inflator's DC input. This allows for continuous operation.

5. Basic Operation Guide

5.1 Preparing for Inflation

1. Select the Correct Nozzle/Adapter:
   • For standard car, SUV, and motorcycle tires (Schrader valve): Use the default quick-connect nozzle.
   • For most bicycle tires (Presta valve): Screw the Presta valve adapter onto the valve stem, then attach the nozzle.
   • For sports balls: Attach the ball needle to the nozzle.
2. Connect the Nozzle: Firmly push the nozzle onto the inflator's air hose outlet until it clicks or is secure.
3. Connect to the Valve: Remove the valve cap from the tire or ball. Press the nozzle firmly onto the valve stem to create a seal.

5.2 Setting the Target Pressure

1. Press the Power button to turn on the unit. The display will light up.
2. Press the Unit button to select your preferred pressure unit (e.g., PSI).
3. Press the Mode button to cycle to the appropriate preset (Car, Motorcycle, etc.) or the "Custom" mode.
4. Use the + and - buttons to adjust the target pressure value to match the recommended pressure for your tire or ball. Consult your vehicle's manual or the tire sidewall for the correct PSI.

5.3 Starting Inflation and Auto Shut-Off

1. Once the target pressure is set, press the Start/Stop button. The motor will start, and the display will show the real-time pressure increasing.
2. Hold the nozzle firmly on the valve stem during inflation.
3. The inflator will automatically stop when the preset target pressure is reached.
4. After the motor stops, quickly remove the nozzle from the valve stem to prevent air from escaping. Replace the valve cap.
5. Press the Power button to turn off the unit.

6. Using the LED Light

The built-in LED light has three modes for emergency use:

1. With the unit on or off, press and hold the Power/LED button for 2 seconds.
2. Each subsequent press and hold will cycle through the modes: Flashlight (steady) -> SOS (flashing pattern) -> Strobe (rapid flash) -> Off.

7. Care and Maintenance

• Storage: Store the inflator and all accessories in the provided storage bag in a cool, dry place.
• Cleaning: Wipe the exterior with a dry, soft cloth. Do not use liquids or submerge any part of the unit.
• Hose and Nozzles: Keep the air hose and nozzles clean and free of debris to ensure a proper seal.
• Battery: For long-term storage, charge the battery to approximately 50% and recharge it every 3 months.
• Fuse Replacement: If the 12V car cable stops working, the fuse may be blown. Replace it with the provided spare fuse.
