EcoFlow DELTA Pro vs Anker 757 PowerHouse
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
Anker 757 PowerHouse costs $2200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 193% more energy (3600Wh vs 1229Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 4800W more surge headroom (7200W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 757 PowerHouse is 55.1 lb lighter (43.9 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
Anker 757 PowerHouse
Anker's older flagship, now a discount play. Solid and durable, but heavy for its capacity and outclassed on charge speed by the newer C-series.
Best for: Buyers who find it discounted below the newer Anker C1000.
Where it falls short:
- 43.9 lb for 1.2kWh is heavy
- 300W solar input is low
- Outclassed by the newer C1000
