Anker SOLIX C1000 vs Goal Zero Yeti 3000X
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 SOLIX C1000 costs $2200 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 187% more energy (3032Wh vs 1056Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 3000X has 1100W more surge headroom (3500W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C1000 is 41.3 lb lighter (28.44 lb vs 69.75 lb).
- Anker SOLIX C1000 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX C1000 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.
The default recommendation for most people. It clears the 1kWh bar, recharges in under an hour, and undercuts almost everything with comparable specs.
Best for: First-time buyers who want one unit for camping and short outages without overpaying.
Where it falls short:
- 2400W surge won't start a sump pump or well pump
- Only 1056Wh — a fridge-plus-devices outage tops out around a day
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
