At a Glance
This comparison targets campers, tailgaters, and light home-backup users deciding between two mid-range EcoFlow LFP stations. The RIVER 2 Pro delivers 800W of running power and 768 Wh of capacity, a clear step up from the RIVER 2 Max at 500W and 512 Wh.
That extra output lets the Pro handle 22 of 53 tested devices versus 20 for the Max, and its 1600W surge doubles the Max's 1000W rating. Both units share the same 3000-cycle LFP chemistry, 220W solar input ceiling, and compatibility with 17 solar panels.
Neither model is expandable or offers UPS functionality. The tradeoff is weight and charge time: the Pro weighs 18.3 lbs compared to 13.4 lbs for the Max, and its solar charge takes roughly 5 hours versus 3.3 hours for the smaller unit.
