Feature Insights & Breakdown


Multi-Input Efficiency Charging

The Renogy DC to DC charger offers unique dual charging options; charge a house battery from a starter battery connected to the car alternator or directly from solar panels. Both methods can charge simultaneously to minimize charging time. With up to 99% MPPT (Maximum Power Point Tracking) efficiency and 94% conversion efficiency, this smart charger fully charges a 1kWh battery in just 2 hours with solar energy.

Soft Start Circuit Design

The voltage at the input end of the 12V DC to DC charger rises gently, preventing instantaneous overvoltage when the car alternator starts. This ensures that the on-board battery charger and starter battery are not damaged and the vehicle can start smoothly.

Ingenious Structure Design

Removable side covers prevent contact between the product terminals and the human body during transportation and daily use, reducing the risk of electrostatic damage and ensuring product stability and safety. The all-in-one NEG terminal design with partition integrates the terminals for solar panels, array starter battery, and house battery, avoiding misconnections and simplifying installation.

Comprehensive Security Assurance

The Renogy 12V DC to DC charger, certified to CE, FCC, and PoHs, includes multiple intelligent protections such as battery isolation, over-voltage protection, battery temperature protection, over-current protection, overheat protection, reverse current protection, and solar panel and alternator reverse polarity protection, ensuring charging safety and protecting your SLA, Gel, AGM, Flooded, and Lithium batteries.

Lightweight and Compact

At only 9.6 inches in length, 5.7 inches in height, and 3.13 pounds in weight, the DC to DC On-Board Charger is easy to install and fits into any tiny narrow installation space. This design addresses the concern of limited room in your vehicle.

Diversified Smart Monitoring

The Renogy DC-DC Battery Charger uses the Modbus protocol and is compatible with various monitoring devices, including the RMS-DCDC monitoring screen, DC Home App, and Renogy One integrated screen. This allows you to manage and monitor your energy easily and remotely in any scenario.
