EcoFlow RIVER 3 Plus Smart Extra Battery (286Wh/572Wh)

EcoFlow RIVER 3 Plus Extra Battery EB300/EB600: choose expansion capacity for your river 3 plus

The EcoFlow RIVER 3 Plus Smart Extra Battery page offers EB300 and EB600 options. Match the selected battery to the energy reserve you want, and check the variant selector for current purchase availability.

Key specifications and configuration

  • EB300 battery capacity: 286Wh.
  • EB600 battery capacity: 572Wh.
  • RIVER 3 Plus combined capacity: 572Wh with EB300, or 858Wh with EB600.
  • Supported cable-free attachment to RIVER 3 Plus.
  • Additional USB-C input and output: up to 140W with compatible equipment.

Select the correct battery variant

This listing is for an extra battery; the RIVER 3 Plus main station is not included. The main station's AC output rating stays the same when capacity is added. The battery's USB-C capability does not mean it provides standalone AC outlets. Confirm device, cable and USB power requirements before using it separately.

If you want the main station and EB300 together, compare the RIVER 3 Max bundle. Choose the battery size based on the current station model and desired runtime.
