EASYLONGER ES270 CPAP Battery Backup Power Supply, 99.9Wh TSA-Friendly Power Bank for ResMed AirMini, AirSense 11, AirSense 10, AirCurve, Luna TravelPAP, Philips DreamStation / 2 – Flight Ready

Q: Which CPAP machines is the ES270 compatible with?
A: The battery includes 4 DC cables specifically designed for major brands, including ResMed (AirSense 10/11, AirCurve 10/11, AirMini), Philips (DreamStation 1/2), and Luna G3. It is the perfect lightweight companion for travel machines like the ResMed AirMini.

Q: How long will it power my CPAP machine?
A: Designed for portability, it typically provides 1 full night (7-9 hours) of therapy. Important: Due to the compact 99.9Wh capacity, you MUST turn OFF the heated humidifier and heated tube to ensure it lasts through the night.

Q: Is this battery FAA/TSA approved for air travel?
A: Yes! The capacity is exactly 99.9Wh. It is fully compliant with FAA/TSA regulations for carry-on luggage. You can take it on any commercial flight without requiring special airline permission. (Note: It must be in your carry-on bag, not checked luggage).

Q: How do I select the correct voltage for my CPAP?
A: Check your CPAP machine's input voltage first. Then, long-press the voltage setting button for 3 seconds to cycle through and select the matching voltage (e.g., 24V for ResMed) on the smart LED screen.

Q: How do I recharge the battery?
A: The fastest way is via the 100W USB-C Port. Using a high-speed PD charger (not included), you can fully recharge the battery in just over 1 hour—perfect for short layovers. It also supports Solar and Car charging.

Q: Can I charge the battery with solar panels?
A: Yes. We recommend using a 60W to 100W solar panel to charge it efficiently during camping trips.

Q: Can it power two CPAP machines at once?
A: No. While it has multiple ports, the 99.9Wh capacity is designed to power a single machine for one night. Connecting two CPAPs would drain the battery in just a few hours.

Q: Does it support pass-through charging?
A: Yes. You can charge the ES270 battery via USB-C while it is simultaneously powering your CPAP machine via the DC port.

Q: Does the battery remember my voltage setting?
A: No. For safety reasons, the voltage resets every time the battery is turned off. You must manually select the correct voltage each time you use it to prevent accidental damage to 12V devices.

Q: How do I turn off the battery?
A: Press and hold the button for 3 seconds to exit fixed voltage mode. If no device is connected, the battery will automatically shut down after a few seconds to save power.

Q: How can I extend the warranty to 2 years?
A: You can extend your warranty by registering on our official website (www.easylonger.com) via the registration prompt or the red scrolling banner.

• Q: Will using this battery damage my CPAP machine?
  A: No. It is designed to be as safe as a wall outlet. To ensure safety, simply use the correct DC cable included for your specific model and select the matching voltage (e.g., 24V for ResMed) on the battery before connecting. It features built-in protection against over-voltage and short circuits.
• Q: My spouse and I use different CPAP brands. Can we share this battery?
  A: Yes. The package includes 4 different DC cables that cover most major brands like ResMed and Philips. You can easily switch the cable and adjust the voltage setting to match each machine’s specific requirements.
• Q: What type of battery is it? Is it dangerous to keep at home?
  A: It uses premium LiFePO4 (Lithium Iron Phosphate) cells, which are non-explosive, incombustible, and extremely safe for home storage. It offers over 3,000+ charge cycles (approx. 10 years of lifespan), making it much more durable than standard lithium-ion batteries.
• Q: I only used the battery once last year and now it won't work. Why?
  A: Batteries can fail if left uncharged for long periods due to self-discharge. To maintain healthy battery cells, we strongly recommend performing a full charge/discharge cycle every 1-2 months, even when not in use. If your battery is completely unresponsive, please contact our support team.

• Q: What is your return policy if it doesn't work with my machine?
  A: We offer a 30-day money-back guarantee. If the battery is not compatible with your device or you are not satisfied, you can return it within 30 days. Please contact us to initiate the return.
