At a Glance
This comparison targets buyers choosing between a high-capacity home backup unit and a lightweight portable charger. The AC200MAX delivers 2200W of running power and 2048 Wh of battery capacity, giving it enough muscle to handle 45 out of 53 tested devices.
The RIVER 2 Max covers 20 of those same 53 devices on just 500W and 512 Wh, a fraction of the larger unit's output. Bluetti's station also supports expansion and accepts up to 900W of solar input across 20 compatible panels, making it far more versatile for off-grid or emergency scenarios.
The tradeoff is significant: the AC200MAX weighs 61.9 lbs compared to 13.4 lbs for EcoFlow's model, and its solar charge time stretches to roughly 7.3 hours versus 3.3 hours for the RIVER 2 Max. Portability and quick top-ups clearly favor the smaller unit.
