The Jackery DC-DC Alternator Charger converts your vehicle’s alternator output into fast, stable charging for Jackery power stations using DC8020 input. Designed for road trips, off-grid travel, van builds, and overlanding, it delivers up to 600W of regulated power while protecting your starter battery and vehicle system. With auto start–stop logic, wide compatibility, and reliable performance across extreme temperatures, it offers a dependable way to recharge your portable power station while driving.
Fast Alternator Charging
The system draws unused alternator output to provide up to 600W of charging power. This enables significantly faster charging compared to standard vehicle ports, delivering up to 1kWh in roughly two hours of driving. It is especially useful for long travel days, remote routes, and situations where wall charging or strong sunlight aren’t available.
Drive-Based Power Generation
Charging begins automatically whenever the engine is running, using your vehicle’s alternator as a continuous power source. This ensures your Jackery power station is replenished during each drive, reducing downtime and creating a consistent, travel-ready charging solution for RVs, SUVs, and overlanding rigs.
Compatibility & Integration
The charger works with both 12V and 24V vehicle systems, covering most fuel-powered vehicles and small marine setups. Output is designed for Jackery units with DC8020 input, delivering stable power and eliminating the need for adapters. With a single connection at installation, the system operates automatically whenever the vehicle runs.
Smart Battery Protection
Integrated safeguards include ACC signal recognition and voltage monitoring. These features prevent starter-battery drain by ensuring charging only occurs when the engine is active. Automatic shutoff protects both the alternator and the primary battery, and helps maintain long-term vehicle reliability.
Installation & Vehicle Setup
The charger connects directly to the vehicle’s main battery, ACC line, and input/output ports through a straightforward wiring layout. Once installed, all charging operations are automatic, requiring no additional action from the driver. For safety, wiring clarity, and long-term reliability, installation is recommended through a professional automotive modification shop.
