Goal Zero Yeti 700 vs EcoFlow RIVER 2
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 costs $600 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 700 holds 164% more energy (677Wh vs 256Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 700 has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 is 12.6 lb lighter (7.7 lb vs 20.3 lb).
- Goal Zero Yeti 700 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
The largest of the rugged compacts. Still not an appliance unit — 600W of output caps what it can drive — but a durable mid-size companion.
Best for: Rugged off-grid use where durability outranks running heavy loads.
Where it falls short:
- 600W output rules out compressors and heaters
- 20.3 lb is heavy for 677Wh
The cheapest way into LiFePO4. 256Wh is a device charger, but at under $200 with a 60-minute recharge it's hard to argue with.
Best for: Budget campers who just need to keep phones, cameras and a laptop alive.
Where it falls short:
- 300W output runs devices only
- 256Wh is a single evening of real use
