At a Glance
This comparison targets buyers choosing between two EcoFlow LFP portables that sit at different ends of the capacity spectrum. The RIVER 2 Pro delivers 800W of running power and 768 Wh of stored energy, while the RIVER 3 offers 300W and 245 Wh.
That gap shows up clearly in device coverage: the RIVER 2 Pro powered 22 out of 53 tested devices versus 17 for the RIVER 3, and every device the RIVER 3 handled was also covered by the larger unit. Solar charging favors the RIVER 2 Pro as well, accepting up to 220W of panel input with 17 compatible panels compared to 110W and 12 panels for the RIVER 3.
The tradeoff is weight and bulk. At 7.7 lbs, the RIVER 3 is less than half the 18.3 lbs of its bigger sibling, making it far easier to toss in a daypack or car trunk.
