Want portable power that recharges on the road? The EcoFlow RIVER 2 Pro + 500W Alternator Charger gives you 5× faster charging while you drive
The EcoFlow RIVER 2 Pro + 500W Alternator Charger bundle is built for people who want reliable power with the convenience of recharging while on the move. Whether you’re camping, travelling, or preparing for emergencies, this combination makes sure you never run out of energy.
With the 500W Alternator Charger, you can recharge the RIVER 2 Pro up to 5 times faster than a standard car outlet. That means a full top-up in as little as 2.1 hours, simply by using the excess energy your vehicle already produces. Every trip becomes a chance to restore power, so you arrive ready to go.

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.
