The converter is a very convenient and useful device for each car. In fact, it is useful wherever only a 12V power supply is available and you would need a local outlet with 230V.
You have a 230V motor drive and you want to fill in the field, where there is no electricity. Now you can help yourself with this converter. The converter is supplied with two cables (one piece with crocodile clips and 1 piece with a plug). Connect the converter directly to a 12V battery with crocodile clips or put the plug into the car outlet.
