Capacity
SOLIX C800 Plus: +256 Wh (+50.0%).
This comparison targets buyers choosing between two compact LFP power stations for camping, tailgating, or light home backup. The SOLIX C800 Plus delivers 1200W of running power and 768 Wh of capacity, giving it a clear edge over the RIVER 2 Max and its 500W output and 512 Wh battery.
That extra headroom matters: the C800 Plus powered 24 out of 53 tested devices compared to 20 for the RIVER 2 Max, and every device the EcoFlow handled, the Anker handled too. Solar charging tops out at 300W on the C800 Plus versus 220W on the RIVER 2 Max, though the smaller EcoFlow still reaches a full charge slightly faster at 3.3 hours thanks to its smaller battery.
The tradeoff is weight. At 13.4 lbs, the RIVER 2 Max is nearly half the heft of the 24 lb C800 Plus, a real factor for hikers and anyone hauling gear on foot.
