Goal Zero Yeti 3000X 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 $2500 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 196% more energy (3032Wh vs 1024Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 3000X has 2000W more surge headroom (3500W vs 1500W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 555 PowerHouse is 39.9 lb lighter (29.9 lb vs 69.75 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.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 3000X. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
A large-capacity unit held back by aging NMC cells. The capacity is real; the cycle life and charge speed are a generation behind.
Best for: Occasional-use backup where low cycle count won't bite.
Where it falls short:
- NMC — ~500 cycles against 4,000 for LiFePO4 rivals
- 69.75 lb and a 4-hour recharge
- 2-year warranty
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
