At a Glance
This comparison targets buyers choosing between two EcoFlow LFP stations that sit in different weight and output classes. The DELTA 3 Plus delivers 1800W of running power with 3600W surge, enough to handle 42 out of 53 devices in our test suite. The RIVER 2 Pro covers 22 of those same 53 devices on its 800W output and 1600W surge.
Battery capacity tells a similar story: 1024 Wh versus 768 Wh. Solar charging separates them further. The DELTA 3 Plus accepts up to 1000W of solar input and can recharge in roughly 3.7 hours, while the RIVER 2 Pro tops out at 220W and needs about 5 hours.
Expandability is exclusive to the DELTA 3 Plus. The tradeoff is weight: the RIVER 2 Pro comes in at 18.3 lbs, roughly 9 lbs lighter than the 27.6 lb DELTA 3 Plus, making it far easier to grab and go.
