Goal Zero Yeti 1000 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 $500 less. Whether that gap is worth closing depends on what you need to run.
- Anker 555 PowerHouse holds 4% more energy (1024Wh vs 988Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000 has 2100W more surge headroom (3600W vs 1500W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 555 PowerHouse is 5.4 lb lighter (29.9 lb vs 35.3 lb).
- Goal Zero Yeti 1000 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 1000 is poor value on paper: 0.82 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 6th-gen Yeti 1000 finally brings a real 2,000W inverter to Goal Zero's mid-size. Now it competes on output, not just toughness.
Best for: Buyers who want Goal Zero's ruggedness with real appliance-starting output.
Where it falls short:
- 35.3 lb for under 1kWh is heavy
- Premium price against lighter rivals
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
