EcoFlow DELTA 3 Plus vs EcoFlow DELTA 3 Max
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 $350 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max holds 100% more energy (2048Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max has 1200W more surge headroom (4800W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Plus is 26.4 lb lighter (28.7 lb vs 55.1 lb).
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
EcoFlow DELTA 3 Max
The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
Where it falls short:
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
