Bluetti AC70 vs Goal Zero Yeti 700
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
Bluetti AC70 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC70 holds 13% more energy (768Wh vs 677Wh), so it runs the same load proportionally longer.
- Bluetti AC70 has 1000W more surge headroom (2000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 700 is 1.7 lb lighter (20.3 lb vs 22 lb).
- Goal Zero Yeti 700 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 700 is poor value on paper: 0.85 Wh per dollar versus 1.54 for the Bluetti AC70. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
768Wh with 1000W output at $499 — it does what the EcoFlow River 2 Pro does, with more output and more weight.
Best for: Campers who need to run a small fridge, not just charge devices.
Where it falls short:
- 22 lb — 5 lb heavier than the River 2 Pro
- Not expandable
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
