Compatibility guide

Start with the machine—not the battery.

Select the exact CPAP model, describe your usual settings, and read the adapter output before choosing a cable or battery. DC settings and supplied cables differ by battery model; use its exact manual.

01
Identify the machine

Use the exact name printed on the CPAP or its adapter.

Choose the exact modelStart with the brand above
02
Describe the night

This changes the starting battery recommendation.

Model names can be similar while voltage and connectors differ. This is a planning result; final electrical compatibility still needs the exact adapter label and cable confirmation.

03 · Your starting path

No battery selectedComplete the machine check first

Confirm your machine first.

Select the exact model, then read the output voltage on its original adapter.

A battery appears only after the compatibility catalog confirms a supported route. This is a planning recommendation, not a final electrical compatibility confirmation.

Why this is the starting point

The machine, cable route and adapter output come before a battery recommendation.

Before you order
  • Confirm the exact CPAP model name
  • Check the voltage printed on its power adapter
  • Match the required cable from the compatibility list
  • Estimate runtime using your comfort settings
Cable and setup check

Confirm the cable in the exact battery manual before purchase.

Every current battery

Eight models. Four clear use-case families.

PRO models add voltage memory and a more precise battery display. Camo models retain their PRO platform and remain separately identified.

*Planning ranges assume humidification and heated tubing are off. Actual nights vary by CPAP model, pressure, leakage, temperature, battery condition and comfort settings.

Verify on the adapter

Three lines prevent most connection mistakes.

01Output voltage

Read the “Output” line, not the wall-input line.

02Exact machine family

AirSense 10, AirSense 11 and AirMini are not interchangeable names.

03Connector direction

Use the exact cable identified for that machine family, and check whether it is included in the selected package.

From box to bedside

Three steps to a backup you have already tested.

Reliable backup is not only a capacity number. It is a confirmed machine, the correct cable and a real test before the outage.

01

Match the exact CPAP.

Find the machine family, confirm the model name and verify the voltage printed on the original power adapter.

Check compatibility →
02

Plan the real runtime.

Include pressure, humidification and heated tubing instead of treating the biggest published number as a promise.

Estimate runtime →
03

Test before the critical night.

Connect the correct cable, choose the correct output and complete an overnight test while wall power is still available.

Read the setup guide →

Before you decide

Questions worth answering before checkout.

Confirm compatibility and realistic runtime before you buy.

Open support center
How do I know which cable my CPAP needs?

Start with the exact machine model and the voltage printed on its original power adapter. The compatibility tool narrows the cable family, and support can confirm the final connection before purchase.

Why is my runtime lower with the humidifier on?

Heating water and a breathing tube adds significant power demand. Published multi-night estimates assume humidification and heated tubing are off unless the page states otherwise.

Can I take every EASYLONGER battery on a plane?

No. ES270 is the airline-oriented 99.9Wh model. Higher-capacity models require a separate travel decision and must not be treated as automatic flight batteries.

What should I test before relying on backup power?

Confirm the cable and voltage, charge the battery fully, account for comfort heat, and complete an overnight test with the exact CPAP settings you normally use.

Can I take every EASYLONGER battery on a plane?

No. ES270 is the airline-oriented 99.9Wh model. Higher-capacity ES720 and ES960 PRO exceed common passenger-aircraft battery limits and should not be presented as flight batteries.

What should I test before relying on backup power?

Confirm the cable and voltage, charge the battery fully, disable or account for comfort heat, and complete an overnight test with the exact CPAP settings you normally use.

What happens if the product is not right for my setup?
