EcoFlow RIVER Pro Extra Battery

Thus far (2/29/2024), everything is working fine. The "extra" battery was attached to the "primary" EcoFlow RIVER Pro unit...with no problems/issues.
Electronics/Display (of "primary") is working quite well (senses "extra" automatically) and is proving useful. Preparing for a series of bad storms (California)...where there will probably (yet again) be power outages. Now have twice (2x) the's a relief. THANKS MUCH PowerGenUSA for the solid service/transaction and fast shipping/delivery!

Great customer service

Thank you for the superb communication and quick shipping! I’ve always ordered directly from EcoFlow or Wellbots, so I was a bit worried, but you guys are pretty amazing! Thanks for the great service!
