EcoFlow DELTA 2 vs EcoFlow DELTA Pro
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 DELTA 2 costs $2300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 252% more energy (3600Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 5000W more surge headroom (7200W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 72.0 lb lighter (27 lb vs 99 lb).
- EcoFlow DELTA Pro is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 2
The value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
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
