  If your ULTIMATE SPEED Inverter has no output power, several factors could be responsible. First, if the environmental temperature is low, try switching the inverter on and off until the connected device receives power. Second, ensure the vehicle's ignition is switched on. Third, the inverter may be overloaded, so reduce the load to be within the specified limits. Finally, the inverter might have overheated; allow it to cool down, ensure sufficient ventilation, and prevent continuous overloading.

  Carmen ThompsonAug 11, 2025
  The absence of output voltage in your ULTIMATE SPEED Inverter could stem from a couple of reasons. It might be overloaded, so try reducing the load to comply with the technical specifications. Alternatively, the input voltage might be too low. Ensure the input voltage remains above 10.5 V to maintain output voltage.

  Jordan RamosAug 17, 2025
  If the low battery voltage signal is sounding repeatedly on your ULTIMATE SPEED Inverter, it could indicate a defective battery, which would need replacing. Another cause might be an insufficient voltage or power supply. Check the condition of the socket for the electrical system and the 12 V motor vehicle cigarette lighter plug, cleaning them if necessary.
