KFFKFF RV Power Converter 80A — Converts 110V AC to 12V DC, 4-Stage Intelligent Charger, 13V-16.5V Adjustable, Lithium & Lead-Acid Compatible, ETL Certified

The KFFKFF RV power converter delivers a stable 12V DC supply from household AC for charging batteries and running 12V appliances (batteries not included). It converts 110V AC (standard 120V AC input) into reliable 12V DC output and supports both lithium and lead-acid battery chemistries with dedicated charging profiles. Featuring 4-stage intelligent charging, the unit optimizes charge cycles and parameters for efficient, safe battery replenishment. A fixed-voltage mode is available and can be set anywhere within the 13V-16.5V range. With up to 80A of clean current, this converter is suited to larger RV battery systems and is ideal for battery capacities around 75Ah to 80Ah. Cooling is handled by a temperature-controlled silent fan that automatically runs when the temperature exceeds the rated temperature and stops once it falls back below. The rugged metal housing aids heat dissipation, helping maintain reliable performance in varied conditions. Safety protections include short circuit, over-temperature, overload, low voltage, over voltage, and reverse polarity protection, and the unit is ETL tested. Heavy-duty 100% pure copper cables are used for superior conductivity, corrosion resistance, and long-term durability.
