|---|---|---|---|
| Refrigerator (modern) | 150 W (1,200 W surge) | yes | ~44 h |
| Chest Freezer | 100 W (1,000 W surge) | yes | ~66 h |
| CPAP Machine (no humidifier) | 40 W | yes | ~58 h |
| CPAP with Heated Humidifier | 60 W (95 W surge) | yes | ~48 h |
| Oxygen Concentrator | 350 W (600 W surge) | yes | ~6.6 h |
| Space Heater (1500 W) | 1,500 W | yes | ~1.5 h |
| Window AC (8,000 BTU) | 715 W (1,250 W surge) | yes | ~4.6 h |
| Window AC (12,000 BTU) | 1,100 W (1,800 W surge) | yes | ~3.0 h |
| Gas Furnace Blower (1/2 HP) | 800 W (2,350 W surge) | yes | ~5.8 h |
| Microwave (1000 W cooking) | 1,200 W | yes | ~1.9 h |
| Sump Pump (1/3 HP) | 800 W (1,500 W surge) | yes | ~14 h |
| Sump Pump (1/2 HP) | 1,050 W (2,150 W surge) | yes | ~11 h |
| Well Pump (1/2 HP) | 1,000 W (2,100 W surge) | yes | ~15 h |
Runtime uses each load's duty-weighted average draw against 90% of the rated capacity — conservative on purpose. Cyclic loads (fridges, pumps) run far longer than running-watts × capacity would suggest.

Common questions
What can the Anker SOLIX SOLIX F2600 run?
With 2,400 W of continuous output and a 2,800 W surge rating, the Anker SOLIX SOLIX F2600 runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, space heater (1500 w), and more. Its 2,560 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.
How long will the Anker SOLIX SOLIX F2600 run a refrigerator?
A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Anker SOLIX SOLIX F2600's 2,560 Wh runs one for roughly 44 h before recharging.
