Anker 757 PowerHouse vs EcoFlow DELTA Max 2000
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 $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 64% more energy (2016Wh vs 1229Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Max 2000 has 1000W more surge headroom (3400W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 757 PowerHouse is 4.1 lb lighter (43.9 lb vs 48 lb).
- Anker 757 PowerHouse uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker 757 PowerHouse is rated for 3,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA Max 2000. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
The previous-generation 2kWh EcoFlow. Still capable and expandable, but its NMC cells and 800-cycle rating are a real step below the LiFePO4 DELTA 3 that replaced it.
Best for: Only at a steep discount against the DELTA 3 Max.
Where it falls short:
- NMC — roughly 800 cycles vs 4,000 for the DELTA 3 Max
- 2-year warranty
