Anker SOLIX F2600
2560 Wh · 2400 W output · LiFePO4 · $1499
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
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.
What we like
- 2560Wh is generous for the price
- 4000 cycles
- 1000W solar input
Where it falls short
- 2800W surge is barely above its 2400W continuous — it will struggle with pumps
- 61.7 lb

Runtime = (capacity × 0.85 inverter efficiency) ÷ appliance watts. Refrigerator assumes a 40% compressor duty cycle. Real-world results vary.
