Goal Zero Yeti 700 vs Anker 555 PowerHouse
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
Anker 555 PowerHouse costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Anker 555 PowerHouse holds 51% more energy (1024Wh vs 677Wh), so it runs the same load proportionally longer.
- Anker 555 PowerHouse has 500W more surge headroom (1500W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 700 is 9.6 lb lighter (20.3 lb vs 29.9 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 1.46 for the Anker 555 PowerHouse. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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
A 1kWh unit whose 1,000W output and slow charging show its age — the newer, cheaper Anker C1000 beats it on nearly every axis.
Best for: Only worth it steeply discounted against the C1000.
Where it falls short:
- 1,500W surge is low
- 200W solar input and a slow 138-minute recharge
