EcoFlow DELTA 3 Plus 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
EcoFlow DELTA 3 Plus costs $250 less. Whether that gap is worth closing depends on what you need to run.
- Anker 757 PowerHouse holds 20% more energy (1229Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 1200W more surge headroom (3600W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Plus is 15.2 lb lighter (28.7 lb vs 43.9 lb).
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Plus
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3

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
