EcoFlow DELTA 3 Max Plus 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
EcoFlow DELTA 1300 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max Plus holds 63% more energy (2048Wh vs 1260Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max Plus has 2700W more surge headroom (6000W vs 3300W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 26.4 lb lighter (30.9 lb vs 57.3 lb).
- EcoFlow DELTA 3 Max Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Max Plus is rated for 4,000 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.
Adds 600W of continuous output and doubles surge headroom over the standard Max, for $200. Worth it only if you're running heavy loads.
Best for: Workshops and job sites where tool startup surge is the constraint.
Where it falls short:
- $200 premium is wasted if your loads are under 2400W
- 57 lb
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
