FAQ
Most Frequently Asked
Q: Which CPAP machines is the ES400 AIR compatible with?
A: The battery includes 4 DC cables specifically designed for major brands, including ResMed (AirSense 10/11, AirMini), Philips (DreamStation 1/2), and Luna G3. Additionally, it features a built-in cigarette lighter socket, allowing you to use your CPAP's car charger cable directly.
Q: How long will it power my CPAP machine?
A: It is designed as a lightweight travel backup and typically provides 1 full night of power. Runtime depends heavily on pressure settings; 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, with conditions. The capacity is 148Wh. According to FAA/TSA regulations (100Wh-160Wh range), you are allowed to bring it in your carry-on baggage (usually limited to 2 batteries per person), but you typically need airline approval. It is strictly prohibited in checked luggage.
Q: How do I select the correct voltage for my CPAP?
A: Check your CPAP machine's input voltage first (e.g., 24V for ResMed). Then, press the voltage button to select the matching output before connecting your device via the DC port.
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 (160W max). This is a great alternative if you have your machine’s car charging cable.
Q: Can I charge the battery with solar panels?
A: Yes. It supports solar charging. We recommend using an 80W (or higher) solar panel with an 18-24V output to ensure efficient charging.
Q: How do I recharge the battery?
A: There are 3 ways to recharge: 1) Via the included AC Wall Adapter (4-5 hours), 2) Via a Car Charger, or 3) Via a Solar Panel.
Q: Does it support pass-through charging?
A: Yes. You can charge the ES400 AIR battery while it is simultaneously powering your CPAP machine, ensuring uninterrupted therapy.
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 the DC port.
Q: How do I turn off the battery?
A: Press and hold the power/voltage button for 3 seconds to turn it off. If no device is connected, the battery will also automatically shut down after a period of inactivity to save power.

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.
