At a Glance
This comparison targets buyers choosing between a high-capacity home backup unit and a lightweight portable station. The AC200MAX delivers 2200W of running power and 2048 Wh of battery capacity, while the RIVER 2 Pro offers 800W and 768 Wh.
That gap shows up clearly in device coverage: the AC200MAX powered 45 out of 53 tested devices compared to just 22 for the RIVER 2 Pro. Expandable battery support on the Bluetti unit adds even more runtime flexibility for extended outages or off-grid setups, and its 900W solar input cuts dependence on wall charging.
The tradeoff is weight. At 61.9 lbs, the AC200MAX is more than three times heavier than the 18.3 lb EcoFlow, making the RIVER 2 Pro far easier to grab for camping trips, tailgates, or any scenario where portability matters most.
