  1. Connect the Adapter: Plug the AC adapter into a working wall outlet.
  2. Connect to the River: Connect the adapter’s DC output to the charging port on the Ecoflow River. The charging indicator lights will illuminate.
  3. Charging Time: Charging time varies depending on the River model and battery capacity:
    • River: Approximately 1.6 – 2.4 hours (full charge)
    • River 2: Approximately 1 – 1.8 hours (full charge)
    • River 2 Pro: Approximately 70 minutes (full charge)

Testing

  • Monitor Charging Lights: Observe the charging indicator lights. Solid green indicates a full charge.
