The ACOPOWER 12V 40A DC to DC charger takes power from your vehicle's starter battery or alternator and charges a separate house battery bank while you drive. A front knob selects the battery chemistry: LiFePO4, AGM, flooded, gel or lithium. It charges in three stages (bulk, boost, float) and tops out at 40A, which is a solid middle ground between small 20A units and heavy 60A+ chargers. It also senses when the engine is running so it does not drain the starter battery, and it isolates input from output. It suits van, RV and overland builds with a modest house bank; large banks or high-output alternators will want more current.

The ACOPOWER 12V 40A DC to DC on-board battery charger charges house batteries from the starter battery. It works with multiple alternator types and charges 12V LiFePO4, AGM, Flooded, Gel and Lithium batteries. A knob lets you select the battery type.
It uses 3-stage smart charging (Bulk, Boost and Float) to charge the battery automatically to 100%. It detects whether the generator is started, which prevents over-discharge of the starting battery and protects the generator. It also isolates input from output to prevent voltage transmission errors and interference with house battery charging.
The charger has over-voltage, over-temperature and reverse polarity protection. Its compact, robust design suits limited space in a vehicle.
