How Long Will the Bluetti AC180 Run a CPAP Machine?

Updated 2026-10-17 · Yes

About 35 hours. The Bluetti AC180 stores 1152Wh, and a CPAP machine averages about 30W. At 8 hours of use a day, one charge lasts about 4.4 days.

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

Recharging with solar

The Bluetti AC180 accepts up to 500W of solar input. In real conditions that harvests about 1.9 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 Bluetti AC180 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 Bluetti AC180’s DC port instead of the AC outlet avoids inverter losses: about 81Wh more usable energy.
  • The Bluetti AC180 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.

FAQ

Will the Bluetti AC180 run a CPAP machine overnight?

Yes. Eight hours uses about 240Wh, roughly 23% of the Bluetti AC180’s usable capacity.

How long does the Bluetti AC180 take to recharge with solar?

With its maximum 500W of solar input it refills in about 3.1 hours of strong sun. With a single 200W panel, expect about 7.7 hours of full sun.

Is the Bluetti AC180 safe for medical equipment?

These are estimates, not medical advice. Check your device’s actual power draw, test your setup before you rely on it, and always keep a backup plan approved by your doctor or equipment supplier.
