Goal Zero Yeti 1000 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
EcoFlow RIVER 2 Max costs $900 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1000 holds 93% more energy (988Wh vs 512Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000 has 2600W more surge headroom (3600W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Max is 22.1 lb lighter (13.2 lb vs 35.3 lb).
- Goal Zero Yeti 1000 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 1000 is poor value on paper: 0.82 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.
The 6th-gen Yeti 1000 finally brings a real 2,000W inverter to Goal Zero's mid-size. Now it competes on output, not just toughness.
Best for: Buyers who want Goal Zero's ruggedness with real appliance-starting output.
Where it falls short:
- 35.3 lb for under 1kWh is heavy
- Premium price against lighter rivals
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
