EcoFlow DELTA Pro 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 $2200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 186% more energy (3600Wh vs 1260Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 3900W more surge headroom (7200W vs 3300W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 68.1 lb lighter (30.9 lb vs 99 lb).
- EcoFlow DELTA Pro uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA Pro is rated for 3,500 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.
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
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
