EcoFlow RIVER 3 vs Goal Zero Yeti 1500X
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 $1760 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 519% more energy (1516Wh vs 245Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 2900W more surge headroom (3500W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 37.8 lb lighter (7.8 lb vs 45.64 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 1500X. 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 previous-generation flagship. Its NMC battery is the catch — far fewer cycles than the LiFePO4 units now around it, including its own replacement.
Best for: Only at a steep discount against the newer LiFePO4 Yeti 1500.
Where it falls short:
- NMC chemistry — roughly 500 cycles vs 4,000 for the new 1500
- 180-minute recharge is slow
- Only a 2-year warranty
