Anker 757 PowerHouse vs EcoFlow DELTA 1300
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
These two cost the same, so the decision comes down to what you're powering.
- EcoFlow DELTA 1300 holds 3% more energy (1260Wh vs 1229Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 900W more surge headroom (3300W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 13.0 lb lighter (30.9 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 1300. 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 original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
