How Much Power Does a CPAP Machine Use? | Hart Medical Equipment

If you use a CPAP machine for sleep apnea therapy, understanding its power consumption is essential—especially when planning for travel, battery backup, or emergency preparedness. At Hart Medical Equipment, we offer a wide range of CPAP devices and accessories, including power solutions that keep your therapy uninterrupted.

CPAP Machine Power Usage: What to Expect

Most CPAP machines consume between 30 to 90 watts per hour, depending on the model and features. Here's a breakdown:

  • Standard CPAP machines: ~30–60 watts/hour
  • CPAP with heated humidifier: ~60–90 watts/hour
  • CPAP with heated tubing: Up to 100 watts/hour

Over an average 8-hour night, this translates to 0.24 to 0.8 kWh, which costs less than $5 per month in electricity for most users.

CPAP Power and Travel Considerations

If you're traveling or preparing for a power outage, here are a few tips:

  • Use DC power when possible to reduce energy loss from AC conversion.
  • Disable the humidifier to extend battery life.
  • Keep batteries warm in cold environments to maintain efficiency.
  • Choose FAA-approved batteries for air travel.

Final Thoughts

While CPAP machines are relatively low in power consumption, having the right accessories ensures your therapy continues smoothly—whether you're at home or on the go. Hart Medical Equipment offers trusted solutions to keep your sleep therapy powered and protected.
