EcoFlow DELTA 2 vs Goal Zero Yeti 3000X
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 2 costs $2300 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 196% more energy (3032Wh vs 1024Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 3000X has 1300W more surge headroom (3500W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 42.8 lb lighter (27 lb vs 69.75 lb).
- EcoFlow DELTA 2 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 2 is rated for 3,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 3000X. 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 value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
A large-capacity unit held back by aging NMC cells. The capacity is real; the cycle life and charge speed are a generation behind.
Best for: Occasional-use backup where low cycle count won't bite.
Where it falls short:
- NMC — ~500 cycles against 4,000 for LiFePO4 rivals
- 69.75 lb and a 4-hour recharge
- 2-year warranty
