Anker SOLIX F2600 vs Goal Zero Yeti 1500X
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 F2600 costs $500 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2600 holds 69% more energy (2560Wh vs 1516Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 700W more surge headroom (3500W vs 2800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1500X is 16.1 lb lighter (45.64 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.
The Goal Zero Yeti 1500X is poor value on paper: 0.76 Wh per dollar versus 1.71 for the Anker SOLIX F2600. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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 previous-generation flagship. Its NMC battery is the catch — far fewer cycles than the LiFePO4 units now around it, including its own replacement.
Best for: Only at a steep discount against the newer LiFePO4 Yeti 1500.
Where it falls short:
- NMC chemistry — roughly 500 cycles vs 4,000 for the new 1500
- 180-minute recharge is slow
- Only a 2-year warranty
