FAQ
Most Frequently Asked
- Q: Which CPAP machines is the ES720 compatible with?
A: The battery includes 4 DC cables designed for most major brands, including ResMed (S9, AirSense 10/11, AirCurve 10/11, AirMini), Philips (DreamStation 1/2), and Luna G3. It also features a cigarette lighter socket, allowing compatibility with almost any CPAP machine if you have the appropriate car adapter.
- Q: How do I select the correct voltage?
A: Before connecting, check your device's input voltage. Then, press the voltage button to cycle through and select the matching output: 12V, 16.5V, 20V, or 24V. (For example, set to 24V for ResMed AirSense 10). - 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 devices requiring lower voltage. - Q: How long will it power my CPAP machine?
A: It features a 266.4Wh capacity and can last up to 26+ hours on a full charge. However, runtime depends heavily on settings. We strongly recommend turning OFF the heated humidifier and heated tube to maximize battery life.
- Q: Can I use the built-in cigarette lighter port for my CPAP?
A: Yes. You can power your CPAP machine using the 12V cigarette lighter socket. However, you will need to use your CPAP’s specific car charging cable (sold separately) with a voltage converter. - Q: Can it power two CPAP machines at once?
A: Yes. You can use the DC port and the cigarette lighter port simultaneously. However, this will significantly reduce runtime, and you will need an additional car adapter cable for the second machine. - Q: Is this battery FAA/TSA approved for air travel?
A: No. The capacity is 266.4Wh, which exceeds the FAA/TSA limit (160Wh) for carry-on batteries. It cannot be taken on a commercial airplane. - Q: How do I recharge the battery?
A: You can recharge via: 1) Wall Outlet (AC adapter included), 2) USB-C PD Charger, 3) Car Outlet, or 4) Solar Panel (100W+, 18-24V).
- Q: Does it support pass-through charging?
A: Yes. You can charge the battery while simultaneously powering your devices. - Q: How do I turn off the battery?
A: Press and hold the voltage button for 3 seconds to exit voltage selection mode. If no device is connected, the battery will automatically shut down after a few seconds. - Q: What is the warranty and return policy?
A: We offer a 30-day money-back guarantee and a standard 1-year warranty. You can extend your warranty to 2 years by registering on our website (www.easylonger.com). - Q: What if I have technical issues?
A: We offer lifetime technical support. Please contact us with your Order Number and approximate purchase date for the fastest assistance.
Regarding Battery Issues
- 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.
For after-sales inquiries
- 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. - Q: What if I have technical issues? How fast is your support?
A: We offer lifetime technical support. Our team typically responds within 24 hours (business days). To speed up your request or warranty claim, please include your Order Number and approximate purchase date in your first message so we can verify your details immediately. - Q: How can I speed up my support request or warranty claim?
