Anker 757 PowerHouse vs EcoFlow DELTA mini
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 mini costs $400 less. Whether that gap is worth closing depends on what you need to run.
- Anker 757 PowerHouse holds 39% more energy (1229Wh vs 882Wh), so it runs the same load proportionally longer.
- Anker 757 PowerHouse has 300W more surge headroom (2400W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 20.3 lb lighter (23.6 lb vs 43.9 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 mini. 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
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
