Goal Zero Yeti 500 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
These two cost the same, so the decision comes down to what you're powering.
- Anker 555 PowerHouse holds 105% more energy (1024Wh vs 499Wh), 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 500 is 17.0 lb lighter (12.9 lb vs 29.9 lb).
- Goal Zero Yeti 500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The Goal Zero Yeti 500 is poor value on paper: 0.71 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.
A rugged, water-resistant unit for people who'll actually beat it up. You pay a premium over similar-capacity rivals for that durability.
Best for: Overlanders and job sites where the unit will get wet, dusty and knocked around.
Where it falls short:
- $699 for 499Wh is expensive per watt-hour
- Only a 2-year warranty vs 5 years from most rivals
- 120W solar input is very low
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
