Yes, the Alternator Charger can charge third-party portable power stations if the following conditions are met:1. Connected via an XT60 cable.2. The battery type is correctly configured in the settings.3. The vehicle battery voltage (12V/24V) is selected based on the actual voltage level.4. The portable power station type is set to third-party 24V battery.
Cable length settings compensate for voltage drop, ensuring accurate voltage readings.Recommendation: Set based on actual measured length of the input cable.
The Alternator Charger uses a boost circuit design, requiring the input voltage to be lower than the output voltage for safe, optimal performance.
Very minimally. The product uses the power generated by the vehicle's alternator. Even if all the electrical devices inside the car are turned off, the alternator still generates power while the vehicle is running. The Alternator Charger harnesses the surplus power generated by the car's alternator and stores it in a portable power station through the charger. The impact on fuel consumption is very minimal.
No drilling is needed. Wiring routes through the firewall near the driver'’s seat. Installation is safe and will not cause damage.
Yes, for users with hands-on experience. However, it is still recommended to contact professional personnel from related workshops for installation.Tip: Avoid hot, sharp, or high-friction areas. Secure all cables and never cover the unit. It may get hot, so avoid direct contact immediately after use.
It delivers up to 500W of power—5× more than the average 100W from a cigarette lighter—allowing faster, more efficient charging while driving.
It works best with fuel-powered, hybrid, and range-extended vehicles.Charging power depends on alternator surplus and may vary with vehicle age or design.
It uses voltage recognition with an adjustable start voltage range of 11V–30V.
Yes, in Reverse Charging Mode via the EcoFlow app (requires XT150 cable and DELTA Series product).
The charger supports 11V–31V input, making it suitable for most 12V or 24V vehicle starter batteries.
