Anker SOLIX F2600 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
Goal Zero Yeti 1000X costs $300 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2600 holds 160% more energy (2560Wh vs 983Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000X has 200W more surge headroom (3000W vs 2800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000X is 30.0 lb lighter (31.68 lb vs 61.7 lb).
- Anker SOLIX F2600 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX F2600 is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 1000X. 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.
An odd spec sheet: 2560Wh of capacity but only 2800W surge — the lowest surge-to-capacity ratio here. Capacity without starting power.
Best for: Long-duration backup of steady loads (lights, electronics, CPAP) rather than motor-driven appliances.
Where it falls short:
- 2800W surge is barely above its 2400W continuous — it will struggle with pumps
- 61.7 lb
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
