This CPAP battery comes with four DC cables for CPAP machines and works with most major brands on the market. Includes ResMed S9, AirSense 10, AirCurve 10, AirMini, AirSense 11, Philips DreamStation and DreamStation 2. With the right cable or a cigarette lighter inverter, it should be compatible with nearly any CPAP machine.

The ES400 AIR CPAP battery can last up to 15 hours or even more on a full charge. However, how long it actually lasts can vary depending on several factors like your CPAP machine's pressure settings, use of the heated tube, and humidifier. For instance, if you're using high pressure and both the heated tube and humidifier, the battery might only last a few hours. To extend battery life, it's a good idea to reduce or turn off these features.

FAA/TSA restrictions that Lithium-ion batteries with a watt-hour rating (Wh) of 100Wh or less are allowed in carry-on baggage and do not require special permission. Lithium-ion batteries with a watt-hour rating (Wh) between 100Wh and 160Wh are also allowed in carry-on baggage but require airline approval. Lithium-ion batteries over 160Wh are generally prohibited from being carried in either carry-on or checked baggage. These batteries are subject to specific regulations under the International Air Transport Association (IATA) rules.

The ES400 AIR CPAP battery has a capacity of 148Wh. This battery is within the FAA/TSA limit for carry-on batteries, but it requires airline approval before you can bring it on a plane. Make sure to get approval from your airline before your flight.

Yes, the ES400 AIR CPAP battery can power two CPAP machines simultaneously using the DC and cigarette lighter ports. But please note that running two CPAP machines at the same time will consume a lot of power. This will significantly reduce the battery’s runtime.

The CPAP battery DC port supports input power up to 72W, with an input voltage of 12-24V, and is compatible with a 5.5mm x 2.1mm plug and with built-in MPPT.

You can charge the battery using these methods:

• Wall Outlet: Use the included AC adapter to charge the battery through a standard wall outlet.
• Car Charger: Use a cigarette lighter to plug(5.5mm x 2.1mm) cable to recharge it.
• Solar Panel: Use a solar panel with an output of 80W or more. The solar panel should have an output voltage within the 12-24V range and come with a 5.5mm x 2.1mm DC plug.

Different CPAP machines operate at different voltages. Before connecting, you need to confirm the operating voltage of your CPAP machine by checking the technical specifications label on the CPAP machine or the AC adapter provided with the CPAP machine. For example, ResMed CPAP series operates at 24V, while Philips CPAP series operates at 12V. Once you have confirmed the operating voltage of your CPAP machine, press and hold the voltage setting button for about 3 seconds. You will see the screen start flashing at 12V. Without waiting, press the button again to cycle through 16.5V, 20V, and 24V. Continue pressing to cycle back to 12V. When the screen displays the voltage that matches your CPAP machine's operating voltage, stop pressing the button. The voltage will lock in after about 3 seconds, and the battery pack will output the voltage displayed on the screen. Then, select the correct cable from the provided DC cables to connect the battery pack to the CPAP machine, and your CPAP machine will be powered.

When you have activated the fixed voltage output mode to power your CPAP machine, after use, simply press and hold the voltage setting button for about 3 seconds to exit the fixed voltage output mode. In the absence of a load, the battery pack will automatically shut down after a few seconds.

Yes, this battery can be recharged by using a solar panel. It has a built-in MPPT, and the DC port supports a maximum input of 72W with an input voltage range of 12-24V. It is compatible with plug sizes of 5.5mm*2.1mm. As long as your solar panel outputs voltage within the 12-24V range and has a DC 5521 plug, it can charge the battery. We recommend using a solar panel with a 80W output or more.

Yes, this CPAP battery can power your AirSense 10. The AirSense 10 operates at 24V, and this battery can be set to output 24V. The package includes a cable for connecting to the AirSense 10 machine. To connect, press and hold the voltage setting button for about 3 seconds. You will see the battery screen start flashing at 12V. Without waiting, press the button again to cycle through 16.5V, 20V, and 24V. Continue pressing to cycle back to 12V. When the screen displays 24V flashing, stop pressing the button. After about 3 seconds, the voltage will lock in. Then, select the DC cable marked 【For AirSense 10】 from the provided cables, connect the battery pack to the CPAP machine, and your CPAP machine will be powered. After use, press and hold the voltage setting button to exit the fixed voltage mode. In the absence of a load, the battery pack will automatically shut down after a few seconds.

Yes, this CPAP battery does support pass-through charging. To use this feature, connect the included adapter to the battery's DC input port, and use the cigarette lighter output port to connect your CPAP machine. Please note that a cigarette lighter cable is not included in the package, so you'll need to purchase one separately. Make sure to get a cable with a voltage converter that matches your CPAP machine’s requirements. The converter's output voltage should align with the operating voltage of your CPAP machine. If you’re unsure whether the cable is correct, please contact our support.

You will need to purchase a cigarette lighter plug to DC cable with a voltage converter that matches the operating voltage of your CPAP machine. Ensure that the DC end is compatible with your CPAP machine’s input size, and the voltage converter’s output matches your CPAP machine's operating voltage.
