4. Setup
4.1 Charging the Device
Before first use, fully charge the portable tire inflator using the provided USB cable and a compatible USB power adapter (not included). The battery indicator on the LCD screen will show the charging status.
4.2 Dual Power Supply Options
The K7 inflator can be powered in two ways:
- Cordless Operation: Use the built-in lithium-ion battery for maximum portability. Ensure the battery is sufficiently charged.
- 12V DC Car Power: If the battery is low or for extended use, connect the inflator to your vehicle's 12V DC cigarette lighter port using the provided DC cigarette lighter cable. This allows for continuous operation without relying on the internal battery.

5. Operating Instructions
5.1 Basic Inflation Steps
- Connect the Inflation Tube: Screw the air hose securely onto the inflator's air outlet. Then, attach the other end of the air hose to the valve stem of the item you wish to inflate. Ensure a tight connection to prevent air leaks.
- Power On and Select Mode: Press the power button to turn on the device. The LCD screen will display the current pressure. Use the mode selection button (often indicated by a gear or 'M' icon) to cycle through the 5 preset modes: Car, Motorcycle, Bicycle, Ball, or Custom.
- Set Desired Pressure: Once a mode is selected, the preset pressure for that mode will be displayed. Use the '+' and '-' buttons to adjust the target pressure to your desired value. You can also switch between pressure units (PSI, KPa, BAR, KG/CM²) if available.
- Start Inflation: Press the start/stop button (often indicated by a play/pause icon or a power symbol) to begin inflation. The device will automatically stop once the preset pressure is reached.
- Disconnect: Carefully disconnect the air hose from the valve stem and then from the inflator. Some air may escape during disconnection, which is normal.

5.2 Preset Modes and Pressure Adjustment
The K7 offers convenient preset modes:
- Car: Typically 26-50 PSI
- Motorcycle: Typically 26-45 PSI
- Bicycle: Typically 30-120 PSI
- Ball: Typically 4-16 PSI
- Custom: Allows manual setting of any pressure within the device's range.

7. Troubleshooting
If you encounter issues with your QKMPOM K7 Tire Inflator, refer to the following common troubleshooting steps:
- Device Not Turning On:
- Ensure the battery is charged. Connect to a power source (USB or 12V DC car port) and try again.
- Press and hold the power button for a few seconds.
- No Air Output / Slow Inflation:
- Check if the air hose is securely connected to both the inflator and the item's valve stem.
- Verify that the desired pressure is set correctly and is higher than the current pressure.
- Ensure the inflator is in the correct mode for the item being inflated.
- Check for any blockages in the air hose or nozzles.
- Inaccurate Pressure Reading:
- Ensure the air hose is fully connected to the valve stem.
- Compare the reading with a known accurate pressure gauge if available.
- Device Overheating:
- If the device feels excessively hot, turn it off and allow it to cool down for at least 15-20 minutes before resuming use. Prolonged continuous operation can cause overheating.
If these steps do not resolve the issue, please contact customer support for further assistance.
