| What the model adds | Lowest battery weight and 99.9Wh airline planning format. | More reserve while remaining in the 101–160Wh airline-approval range. | Strong capacity-to-weight balance for weekends and ground travel. | 297.6Wh, LiFePO4 cells and 3+ nights of planning range with humidifier and heated tube off. Heavier than ES720. |
Night ranges assume humidification and heated tubing are off. Actual runtime varies by CPAP model, pressure, mask leakage, temperature and battery condition. Charge times use current EASYLONGER published references and vary by input.
Start from the night you need to protect
Choose the scene that matches your next real use, then verify the exact CPAP, cable and comfort settings.
Start with ES270 when carry-on size matters, then confirm the operating airline and exact CPAP setup.
Shop travel-size backup
The ES720 family balances a larger reserve with a portable outdoor setup.
Explore ES720 family
The ES960 family offers the longest reserve in this range. Test the complete bedside setup before the grid fails.

Choose the family from the number of nights, use frequency and battery chemistry.
PRO models add control or convenience upgrades. Confirm the exact feature set on the product page.
Camo remains within its PRO family. It should not be presented as the standard PRO product.

Owner photos are shared with permission. Your setup may look different — always confirm the cable and voltage for your CPAP.
Verify before purchase
Capacity alone does not confirm compatibility or runtime. These three checks reduce uncertainty before checkout.
Use the model label on the CPAP, not the shape of the connector or a broad machine family name.
Read the original adapter output and use the documented machine-specific DC cable.
Run one complete night with your pressure, humidifier and heated tube settings, then keep a reserve.
Common choice questions
Start with travel limits, the number of nights and your exact CPAP setup. Each product page and manual lists the model-specific limits.
ES270 is designed around the common 100Wh threshold. Airline rules and approval remain carrier-specific. ES400 AIR may require prior approval, while ES720 and ES960 families exceed common passenger-aircraft limits.
No. Start from the number of nights, travel limits, weight and charging opportunities. Then confirm compatibility and runtime with the exact CPAP setup.
Only the ES960 series should be described as LiFePO4. Do not apply that chemistry claim to ES270, ES400 AIR or ES720 models.
Humidification and heated tubing add a large variable load. Test the settings you actually use instead of relying on a maximum night range.
The correct cable depends on the exact CPAP model, voltage and connector. Use the compatibility guide or send support clear photos of the machine and original adapter labels.
PRO identifies the upgraded interface or control set within a family. Camo identifies the finish; it does not create a separate capacity class.
