The additional battery doubles the capacity of the EcoFlow River Portable Power Station from 288 Wh to 576 Wh. The EcoFlow RIVER Extra Battery CANNOT be used alone. You will need to install the module on EcoFlow RIVER to use.

After integrating the Extra Battery to EcoFlow RIVER, you will get the EcoFlow RIVER Bundle (also sold as the EcoFlow River Max Portable Power Station) which is monitored and managed as a whole by the BMS of the main model. It provides a cost-effective solution to upgrade your EcoFlow RIVER in terms of storage. With a capacity of 576Wh, the EcoFlow RIVER Bundle provides enough juice to run essential devices for hours, depending on the actual output.

With the EcoFlow patented X-Stream Technology, the smart inverter enables a fast recharge that takes less than 1 hour to charge from 0%-80%, and it gets fully charged in 1.6 hours. You can switch to a quieter charging condition by turning on the “Quiet Charging” status on the APP.

The X-Boost Technology’s advanced built-in algorithm enables most heavy-duty kitchen appliances and tools (up to 1800W) to operate. With X-Boost, EcoFlow RIVER Max can power 80% of essential home appliances and devices, especially those within 1200W for a better using experience. The discharging rates and X-Boost mode can be monitored and controlled through the EcoFlow APP
