EcoFlow DELTA 3 Ultra Plus vs Goal Zero Yeti 200X
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
Goal Zero Yeti 200X costs $1700 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra Plus holds 1543% more energy (3072Wh vs 187Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra Plus has 7000W more surge headroom (7200W vs 200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 200X is 80.5 lb lighter (5 lb vs 85.5 lb).
- EcoFlow DELTA 3 Ultra Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Ultra Plus is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 200X. 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 Ultra's solar problem solved: same everything, but 1600W of PV input instead of 800W. That doubles your off-grid refill speed for $200.
Best for: Off-grid cabins and van builds that actually recharge from panels.
Where it falls short:
- $1999 approaches DELTA Pro 3 pricing
- 85.5 lb
A tiny, well-built unit for USB devices and small electronics. The 120W AC inverter and Li-ion cells make it a charger, not a power station.
Best for: Ultralight trips charging phones, cameras and a small laptop.
Where it falls short:
- 120W AC output runs almost nothing with a plug
- ~500 cycles, 2-year warranty
