EcoFlow DELTA Pro vs Goal Zero Yeti 6000X
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 Pro costs $2300 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 6000X holds 69% more energy (6071Wh vs 3600Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 3700W more surge headroom (7200W vs 3500W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA Pro is 7.0 lb lighter (99 lb vs 106 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 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 6000X. Its NMC cells are rated for 500 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
A huge-capacity home unit whose weakness is the same as its siblings: NMC cells with a low cycle count, at a flagship price.
Best for: Large-capacity backup for infrequent, deep-discharge use.
Where it falls short:
- NMC — ~500 cycles
- 2,000W output is low for the capacity
- 106 lb, 2-year warranty
