Dometic PerfectPower DCC 1224-20

This DC charging converter transforms 12 V input voltage to 24 V and ensures that the leisure battery is optimally charged during the drive at all times – so you will never end up with an empty battery when you arrive at your destination. Highly recommendable for modern EURO 6 vehicles with smart alternators. And also for vehicles where the cable cross section is too small to supply the connected devices.
