How Long Will the Anker SOLIX C1000 Gen 2 Run a CPAP Machine?

Updated 2026-10-17 · Yes

About 31 hours. The Anker SOLIX C1000 Gen 2 stores 1024Wh, and a CPAP machine averages about 30W. At 8 hours of use a day, one charge lasts about 3.9 days.

Medical equipment: these are estimates. Test your own setup and keep a backup plan.

Recharging with solar

The Anker SOLIX C1000 Gen 2 accepts up to 600W of solar input. In real conditions that harvests about 2.3 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. A CPAP machine uses about 240Wh a day at 8 hours of use, so with enough panels and good sun the Anker SOLIX C1000 Gen 2 can run it indefinitely.

Tips

  • Figures assume the humidifier and heated tube are off. Running a CPAP from its 12V/DC adapter instead of the AC outlet stretches runtime noticeably.
  • Running it from the Anker SOLIX C1000 Gen 2’s DC port instead of the AC outlet avoids inverter losses: about 72Wh more usable energy.
  • The Anker SOLIX C1000 Gen 2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
