PowerMax PM4-35A 35 Amp RV Power Converter Charger, 12V Smart 4-Stage Battery Charger, 110V AC to 12V DC, Adjustable 13-16.5V Output, Lithium Compatible
PowerMax's PM4-35A 35 Amp smart 4-stage RV converter charger, 110V AC to 12V DC with adjustable 13-16.5V output.
An RV battery charger, often built into your converter, replenishes your house batteries from shore power, a generator, or solar and keeps them topped off without overcharging. It matters to every RVer because a dead or sulfated battery bank cuts your lights, water pump, and fridge controls short. When shopping, choose a multi-stage smart charger that automatically moves through bulk, absorption, and float stages to extend battery life. Match the charger to your battery chemistry, lithium banks need a charger with a dedicated lithium profile, while AGM and flooded batteries have different voltage needs. Check amperage output against your bank size, look for temperature compensation, reverse-polarity protection, and quiet operation if the unit lives inside your living space.
