EcoFlow DELTA Pro vs EcoFlow DELTA 3 Max Plus
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 3 Max Plus costs $1900 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 76% more energy (3600Wh vs 2048Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 1200W more surge headroom (7200W vs 6000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Max Plus is 41.7 lb lighter (57.3 lb vs 99 lb).
- EcoFlow DELTA 3 Max Plus is rated for 4,000 cycles vs 3,500 — 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 DELTA 3 Max Plus
Adds 600W of continuous output and doubles surge headroom over the standard Max, for $200. Worth it only if you're running heavy loads.
Best for: Workshops and job sites where tool startup surge is the constraint.
Where it falls short:
- $200 premium is wasted if your loads are under 2400W
- 57 lb
