    PRODUCT REVIEW

      • DOUBLE CAPACITY FROM 288Wh TO 576Wh The RIVER 600 Extra Battery is designed to integrate with RIVER 600 to increase the energy capacity of the unit. You can easily double the capacity of the RIVER 600 from 288Wh to 576Wh by attaching the RIVER 600 Extra Battery to the main model. The RIVER 600 Extra Battery CANNOT be used alone. You will need to install the module on RIVER 600 to use.
      • RIVER + EXTRA BATTERY = RIVER MAX After integrating the Extra Battery to RIVER, you will get the 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 RIVER in terms of storage. With a capacity of 576Wh, the RIVER 600 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, RIVER 600 Max can power 80% of essential home appliances and devices, especially those within 1200W for a better user experience. The discharging rates and X-Boost mode can be monitored and controlled through the EcoFlow APP.
