EcoFlow RIVER 2 Max vs Goal Zero Yeti 200X
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
These two cost the same, so the decision comes down to what you're powering.
- EcoFlow RIVER 2 Max holds 174% more energy (512Wh vs 187Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 Max has 800W more surge headroom (1000W vs 200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 200X is 8.2 lb lighter (5 lb vs 13.2 lb).
- EcoFlow RIVER 2 Max uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow RIVER 2 Max 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 200X. 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.
Double the River 2's capacity and output for $100 more. The sweet spot of EcoFlow's small line for anyone eyeing the occasional small appliance.
Best for: Campers who want headroom over a pure device charger without the size of a 1kWh unit.
Where it falls short:
- Still not enough output for heaters or compressors
- 220W solar input is modest
A tiny, well-built unit for USB devices and small electronics. The 120W AC inverter and Li-ion cells make it a charger, not a power station.
Best for: Ultralight trips charging phones, cameras and a small laptop.
Where it falls short:
- 120W AC output runs almost nothing with a plug
- ~500 cycles, 2-year warranty
