Why ES720 fits this backup plan

  • 266.4Wh multi-night reserve

    Built for weekends away and longer outages where a compact one-night battery is not enough.

  • Selectable CPAP output

    Confirm the machine, cable and original-adapter voltage before choosing 12V, 16V, 19V or 24V.

  • Four documented CPAP cables

    The included set supports the listed CPAP families without relying on a generic connector guess.

  • Pass-through backup route

    Keep the tested CPAP setup ready while compatible input power is available.

  • Three practical recharge routes

    Prepare wall, vehicle or compatible solar charging around the actual outage or trip.

  • Ground and off-grid planning

    Capacity above 160Wh makes this a ground, campsite and home-backup platform rather than a passenger carry-on battery.

The planning range assumes humidification and heated tubing are off and is not a guarantee. Runtime changes with the CPAP model, pressure, mask leak, room temperature, battery condition and comfort settings. Confirm the cable and voltage, then run one complete overnight test.

Why this model exists

Built for the nights that need more than a travel battery.

Inside the product

Before checkout

Questions that change the product decision.

Visit support
Can selecting the wrong voltage during setup damage my CPAP?
Not while the CPAP is still disconnected. You can cycle through the voltage choices during setup without sending power to the CPAP. Stop at the voltage printed on the original adapter before connecting the cable. If the wrong voltage was selected, disconnect the CPAP, exit voltage mode and reset the output before reconnecting.
Can I use pass-through charging overnight?
Pass-through availability and the permitted charger depend on the exact ES720 manual. When the manual permits it, power travels from the charger through the battery to the CPAP; it does not bypass the battery. Keep the battery ventilated and test the complete setup before relying on it overnight.
How many nights can I expect?
Use the product planning range with humidification and heated tubing off as a starting point. Pressure, leakage, CPAP model, temperature and battery condition change the result.
How do I know which cable my CPAP needs?
Match the complete CPAP model and adapter voltage in the compatibility guide. Connector shape alone is not enough.
What should I test when it arrives?
Charge fully, verify voltage and cable, then run one complete night using the settings you plan to rely on.
What purchase protection is included?
Purchases from easylonger.com include a 5-year warranty. Purchases from other authorized platforms include 3 years and can be registered on our website to upgrade eligible coverage to 5 years. Lifetime product support, 30-day free returns and free U.S. shipping apply to eligible official-site orders.
ES720 CPAP battery not charging?
1. Wake the battery. If a small amount of charge remains, discharge it until the battery can no longer operate. If it is already fully depleted, press and hold the power button to restart and wake it. Connect the AC adapter, wait briefly, and check for a blue indicator.

2. Try USB-C PD charging. If there is still no response, use a PD-compatible USB-C adapter and cable rated above 60W. Leave it connected to the USB-C port for at least 6 hours.

Indicator guide:
• Blue light flashing: charging normally.
• Fourth blue light flashing: nearly full.
• All four blue lights steady: fully charged.

A charger below 60W or one without the PD protocol may charge extremely slowly or fail to start charging. If no blue indicator appears after more than 6 hours with a verified 60W+ PD charger and cable, email support@easylonger.com for further assistance.
