Want to recharge your power station while you drive? The EcoFlow 500W Alternator Charger makes it 5× faster and keeps you powered on every trip.
The EcoFlow 500W Alternator Charger is the perfect solution if you want to recharge your power station quickly and efficiently while on the road. Instead of relying on slow vehicle auxiliary outlets, this smart charger uses excess energy from your car’s alternator to deliver fast, reliable charging. That means you can top up your EcoFlow power station in just 2.1 hours, 5 times faster than traditional methods.
This 3-in-1 device is more than just a charger. It also works as a maintainer and jump starter, saving you space, time and money by combining three essentials into one compact unit. With its smart DC-DC converter, it makes the most of your vehicle’s output, so you’re never left short of power on road trips, camping getaways, or off-grid adventures.

Note: “DELTA” and “RIVER” refer to ECOFLOW INC. products. RIVER/RIVER 2/RIVER 3 only support XT60. DELTA supports both XT60 and XT150.
Note: Do not block the power button when installing the Alternator Charger. After connecting via XT60, press the power button each time you start the car before charging through the app.
