EcoFlow DELTA 3 Plus vs Goal Zero Yeti 1000X
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 $450 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 4% more energy (1024Wh vs 983Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 600W more surge headroom (3600W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Plus is 3.0 lb lighter (28.7 lb vs 31.68 lb).
- EcoFlow DELTA 3 Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
We'd skip the Goal Zero Yeti 1000X in this matchup. It costs $450 more than the EcoFlow DELTA 3 Plus while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
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
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
