EcoFlow RIVER 2 Max vs Goal Zero Yeti 1000X
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 1000X holds 92% more energy (983Wh vs 512Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000X has 2000W more surge headroom (3000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Max is 18.5 lb lighter (13.2 lb vs 31.68 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.
The Goal Zero Yeti 1000X 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.
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
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
