Extra battery for EcoFlow River
*Please NOTE: This item is only applicable to orders in the US mainland states(except Hawaii, Alaska, Puerto Rico and Virgin Islands).
The EcoFlow River Extra Battery is designed to integrate with EcoFlow River to increase the energy capacity of the unit. You can easily double the capacity of the EcoFlow River from 288Wh to 576Wh by attaching the EcoFlow River Extra Battery to the main model. The EcoFlow River Extra Battery cannot be used separately.
Key Features of the Ecoflow River
-
Thanks to its smart X-Stream integrated inverter, the River can charge from 0% to 80% in only 1 hour. You can switch to a quieter charging condition by turning on the “Quiet Charging” status on the Ecoflow app.
-
The extra battery doubles the capacity from 288Wh to 576Wh for when you need more power, you can also detach the extra battery easily for more portability.
The Extra Ecoflow Battery
With the EcoFlow patented X-Stream Technology, the smart inverter enables fast recharging. Even after adding the Extra EcoFlow Battery to River, recharging time from an AC wall outlet remains the same. It’ll still take less than 1 hour to charge from 0%-80%, and fully charge in 1.6 hours.
EcoFlow River+ Extra Battery = EcoFlow River Max
After integrating the Extra Battery to a River unit, you will get the River Bundle which is monitored and managed as a whole by the BMS (Battery Management System) of the main model. It provides a cost-effective solution to upgrade your River in terms of storage. With a capacity of 576Wh, the River Bundle provides enough juice to run essential devices for hours.
Benefits of the River
-
Lightning-fast charging means that you can have an uninterrupted power supply anywhere you go.
-
Having more capacity gives you more energy to use between recharges cycles.
-
Faster charging means that you have less downtime, and more time powering your devices.

Wanted the River Max
I wanted the River Max, but decided to get the River instead. After a month of using, I decided to just get an extra battery, so happy this was an option!
