Dometic PerfectCharge DCDC 12 DC-DC akkulaturi 170 W hopea (9600000039)

Service batteries in vehicles often suffer from undercharging due to voltage drop in long cable runs or the smart alternator's variable output. The Dometic PerfectCharge DCDC 12 solves this by boosting the input voltage to deliver a stable, multi-stage charge to your auxiliary battery, ensuring it reaches full capacity and lasts longer.

Who is it for

This charger is ideal for RV, boat, and truck owners who need to charge a 12 V service battery (lead-acid or LiFePO4) from the vehicle's starter battery or alternator while driving. It is also suitable for indoor use as a power supply or voltage converter.
