EcoFlow RIVER 3 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 RIVER 3 costs $960 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1000X holds 301% more energy (983Wh vs 245Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000X has 2400W more surge headroom (3000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 23.9 lb lighter (7.8 lb vs 31.68 lb).
- EcoFlow RIVER 3 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 3 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 1000X. 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.
A glorified power bank with AC outlets — and that's fine if that's what you need. 245Wh runs devices, not appliances.
Best for: Weekend campers charging phones, cameras and a laptop.
Where it falls short:
- 300W output rules out anything with a heating element
- No expansion path
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
