Goal Zero Yeti 300 vs EcoFlow RIVER 2 Max
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 72% more energy (512Wh vs 297Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 Max has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Max is 0.5 lb lighter (13.2 lb vs 13.7 lb).
- Goal Zero Yeti 300 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 300 is poor value on paper: 0.99 Wh per dollar versus 1.71 for the EcoFlow RIVER 2 Max. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
Goal Zero's compact entry: rugged and IPX4-rated, but you pay a premium over similar-capacity rivals for the drop-and-splash toughness.
Best for: Overlanders and job sites where the unit gets wet and knocked around.
Where it falls short:
- 350W output runs devices, not appliances
- $299 for 297Wh is pricey per watt-hour
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
