EcoFlow DELTA Pro 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 $3000 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 1306% more energy (3600Wh vs 256Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 6600W more surge headroom (7200W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 is 91.3 lb lighter (7.7 lb vs 99 lb).
- EcoFlow DELTA Pro is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
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
