DOUBLE CAPACITY FROM 288Wh TO 576Wh
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 alone. You will need to install the module on EcoFlow RIVER to use.
EcoFlow RIVER + EXTRA BATTERY = EcoFlow RIVER MAX
After integrating the Extra Battery to EcoFlow RIVER, you will get the EcoFlow RIVER Bundle 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.
RECHARGE FROM 0% TO 80% WITHIN 1 HOUR
With the EcoFlow patented X-Stream Technology, the smart inverter enables a fast rechargeability 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.
COMPATIBLE WITH 80% HOME APPLIANCES
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.
