The EcoFlow RIVER 2 Max is a 512 Wh portable power station with a LiFePO4 battery rated for around 3,000 charge cycles. It charges from a wall outlet in about an hour, accepts up to 220 W of solar input, and its AC output runs up to 500 W continuous with X-Boost for higher-draw appliances. It suits campers, van dwellers and home backup users who want fast recharging and long battery life. Against the smaller RIVER 2 and RIVER 2 Pro, it sits in the middle on capacity, and rivals like the Jackery Explorer 500 offer similar capacity but slower charging and shorter battery lifespan.
