EcoFlow DELTA 3 Plus vs EcoFlow RIVER 2
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow RIVER 2 costs $550 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 300% more energy (1024Wh vs 256Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 3000W more surge headroom (3600W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 is 21.0 lb lighter (7.7 lb vs 28.7 lb).
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Plus
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
EcoFlow RIVER 2
The cheapest way into LiFePO4. 256Wh is a device charger, but at under $200 with a 60-minute recharge it's hard to argue with.
Best for: Budget campers who just need to keep phones, cameras and a laptop alive.
Where it falls short:
- 300W output runs devices only
- 256Wh is a single evening of real use
