Drive, charge, consume! The EcoFlow 500 W alternator charger turns every trip into useful energy for your DELTA 3 Plus / Delta 3 Pro / RIVER power stations, your WAVE air conditioner, or your GLACIER cooler/freezer.
Onboard a van, 4x4, or RV, gain true off-grid autonomy with fast charging while driving, without needing a mains connection.
⚡ How does the EcoFlow 500 W Alternator Charger work?
- Connection. Connect the battery + via the fuse cable and the chassis ground; plug the XT60 output to the power station. No drilling required, clean installation on the provided mount.
- Conversion. The 500 W DC-DC converter captures surplus alternator energy and continuously charges the power station (12/24 V input).
- Control. Choose 1 of 3 charging modes (fast charge, reverse charge, or battery maintenance) and monitor progress on the EcoFlow app, or from your dashboard via Apple CarPlay / Android Auto.
