Safety Information
Your safety is paramount. The VTOMAN X5 is equipped with multiple safety features to protect both the user and the device. Adhere to the following guidelines:
- Always ensure proper connection of jumper cables. The device features an indicator light that will show a reverse red light if connections are incorrect, preventing sparks and damage.
- The unit incorporates comprehensive protection features including: spark-proof, reverse-charge, over-current, over-charge, reverse-polarity, high-temp, low-temp, short-circuit, over-voltage, and over-load protection.
- Do not operate the air compressor continuously for extended periods. If the unit becomes excessively hot during inflation, allow it to cool down for several minutes before resuming operation.
- The Type-C port is the only input charging port. The DC output port is exclusively for powering car products (e.g., vacuum cleaners) and is not a charging input. Use only Type-C cables for charging the X5. Improper charging can lead to safety hazards.
- Keep the device away from water, moisture, and flammable materials.
- Do not disassemble or attempt to repair the unit yourself. Contact customer support for assistance.
- Store the device in a cool, dry place, out of reach of children.

Setup
Initial Charging
Before first use, fully charge your VTOMAN X5.
- Locate the USB-C input port on the device.
- Connect the provided USB-C to USB-C cable (or USB-A to USB-C cable with a compatible adapter) to the input port.
- Plug the other end of the cable into a suitable USB wall charger (not included).
- The screen will indicate charging status. Charge until the battery indicator shows full.
Note: The X5 supports 18W fast charging. A full charge can take several hours depending on the charger's output. The device can hold a charge for up to 24 months in standby.

Operating Instructions
Jump Starting a Vehicle
Follow these steps to safely jump start your vehicle:
- Insert: Plug the smart jumper cable into the jump starter's port. Ensure it is fully inserted.
- Connect: Attach the red clamp to the positive (+) terminal of your vehicle's battery and the black clamp to the negative (-) terminal. The smart cable indicator light will turn green if connected correctly. If it shows a red light, check your connections.
- Use Boost Function (if needed): If your car battery is completely dead or too low for the jump starter to detect, press the "BOOST" button on the smart cable.
- Start your vehicle: Once the indicator is green, start your vehicle's engine.
- Detach & Go: After the engine starts, immediately remove the jumper clamps from the car battery, then disconnect the smart cable from the jump starter.

Inflating Tires and Other Inflatables
The integrated air compressor can inflate tires, balls, and other items:
- Assemble the tube: Screw the pump tube onto the inflation port of the X5.
- Connect the tube: Attach the appropriate air nozzle to the pump tube and connect it securely to the item you wish to inflate (e.g., tire valve stem).
- Adjust the inflation mode: Use the controls on the X5's screen to select the desired inflation mode (car, motorcycle, bicycle, ball) and set the target pressure (PSI, BAR, or KPA).
- Press the power button to start work: Press the power button to begin inflation. The compressor will automatically stop once the preset pressure is reached.
Note: The X5 can inflate a typical car tire (0 to 20 PSI) in approximately 2 minutes.
