Goal Zero Yeti 500 vs EcoFlow RIVER 3
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 $460 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 500 holds 104% more energy (499Wh vs 245Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 500 has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 5.1 lb lighter (7.8 lb vs 12.9 lb).
- Goal Zero Yeti 500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
A rugged, water-resistant unit for people who'll actually beat it up. You pay a premium over similar-capacity rivals for that durability.
Best for: Overlanders and job sites where the unit will get wet, dusty and knocked around.
Where it falls short:
- $699 for 499Wh is expensive per watt-hour
- Only a 2-year warranty vs 5 years from most rivals
- 120W solar input is very low
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
