Goal Zero Yeti 1500 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 $1400 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500 holds 194% more energy (1505Wh vs 512Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500 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 39.5 lb lighter (13.2 lb vs 52.75 lb).
- Goal Zero Yeti 1500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 1500 is poor value on paper: 0.89 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 new-for-2026 LiFePO4 Yeti 1500 — a big durability and cycle-life upgrade over the older 1500X it replaces.
Best for: Home backup buyers who want Goal Zero's build with modern battery chemistry.
Where it falls short:
- 52.75 lb — a two-hand lift
- 600W solar input is modest for the capacity
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
