Charging the internal battery
The device features an automatic charger with a Floating System. To charge:
- Place the unit vertically.
- Connect the power supply to a 230V outlet and the device.
- The green indicator shows the battery is fully charged.
- If the device remains in charging mode for more than 24 hours (red/orange light), stop charging as the battery may be damaged.
Using as a 12V DC power supply
The cigarette lighter socket is protected by a 20A thermal circuit breaker. To use:
- Set the switch to OFF.
- Open the socket cap and insert the electrical device's plug (cable not included).
Using the air compressor
- Ensure the device switch is set to OFF.
- Connect the air hose to the item to be inflated.
- Press the ON button to start the compressor.
- Monitor the pressure gauge and stop when the desired pressure is reached.
- The compressor should run for a maximum of 10 minutes. Allow 10 minutes to cool down before reuse.
Maintenance and battery replacement
Regularly clean the device with a dry cloth and remove dust from the casing. Maintenance should be performed by qualified personnel. To replace the battery:

- Disconnect the unit from the power supply.
- Unscrew the 15 screws on the back panel and remove it.
- Disconnect the battery terminals (+ and -).
- Remove the battery and install a new one, ensuring correct polarity (terminal - on the left, + on the right).
- Tighten the nuts to 4 N.m and reattach the back panel.
Troubleshooting
If the device beeps, it detects polarity reversal; check the battery connections. If sparks appear, ensure the switch is OFF before connecting clamps. If the unit fails to start the vehicle, ensure the battery is charged and the vehicle battery is 12V.
