What to Look For Before Buying

Choosing the right battery for your CPAP requires considering your travel needs and device compatibility. Always check your machine’s power requirements and the battery’s capacity before buying.

Check Verify Airline Compliance

If you plan to fly, ensure your battery is under 100Wh to meet FAA and TSA regulations. Some airlines allow batteries up to 160Wh with prior approval, but 100Wh is the safest bet. Always carry your battery in your carry-on luggage, as lithium batteries are prohibited in checked bags.

Check the manufacturer’s label to confirm the watt-hour rating before heading to the airport.

Value Assess Your Runtime Needs

Calculate the total hours you need to power your CPAP per night. Remember that humidification and heated tubing significantly drain battery life. If you are camping for several days, choose a high-capacity unit.

Rating Check Device Compatibility

Not every battery works with every CPAP machine. Ensure the battery includes the correct DC power cable for your model. An automatic voltage-adjusting battery can save you much frustration.

Verify Look for Pass-Through Charging

Pass-through charging is a vital feature for home backup. It allows the battery to power your CPAP while plugged into the wall, automatically switching to battery power during an outage.
