Anker 555 PowerHouse vs Goal Zero Yeti 1000X
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 983Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000X has 1500W more surge headroom (3000W vs 1500W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 555 PowerHouse is 1.8 lb lighter (29.9 lb vs 31.68 lb).
- Anker 555 PowerHouse uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker 555 PowerHouse is rated for 3,000 cycles vs 500 — meaningful if you cycle it daily.
The Goal Zero Yeti 1000X 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.
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
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
