Need fast, reliable power on the go? The EcoFlow RIVER 3 Max Plus+500W Alternator Charger keeps you charged 5× faster while you drive
The EcoFlow RIVER 3 Max Plus+500W Alternator Charger is a bundle designed for travellers, campers, and anyone who needs reliable portable power that recharges quickly on the road. With this setup, you get the flexibility of a powerful portable power station and the convenience of an alternator charger that works while you drive.
The 500W Alternator Charger restores power to your RIVER 3 Max Plus up to 5 times faster than a standard car outlet. That means a full recharge in as little as 2.1 hours. By using excess energy already generated by your vehicle, you turn every kilometre into free, usable power.
Note: “DELTA” and “RIVER” refer to ECOFLOW INC. products. RIVER/RIVER 2/RIVER 3 support XT60 only. DELTA supports XT60 and XT150.
Note: Do not block the power button when installing. After connecting via XT60, press the power button each time you start the car before using the app to charge.
