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 ES720 CPAP battery can last up to 24 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 ES720 CPAP battery has a capacity of 266.4Wh, which exceeds the FAA/TSA limit for carry-on batteries. Therefore, it cannot be taken on a plane.
Yes, the ES720 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 96W, with an input voltage of 18-24V, and is compatible with a 5.5mm x 2.1mm plug. USB-C port supports input power up to 60W and with built-in MPPT.
You can charge the battery using these methods:
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 red voltage indicator light 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 voltage indicator light 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 96W with an input voltage range of 18-24V. It is compatible with plug sizes of 5.5mm*2.1mm. As long as your solar panel outputs voltage within the 18-24V range and has a DC 5521 plug, it can charge the battery. We recommend using a solar panel with a 100W 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 red voltage indicator light 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 red voltage indicator light 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.
Awesome performance! I used this battery 4 nights straight on a full charge and it only dropped 1 bar. I am able to use my CPAP in the field with my military unit without being affected by sleep apnea.
I bought this to power my Resmed Mini Travel CPAP machine for unexpected power losses such as hurricanes and for camping, etc. From a full charge I used it for 5 nights at 6-7 hours per night to test it and it worked like a champ! I did not test it to zero charge so I don't know how many more nights it would have worked but it was down to one light. I recommend keeping the instructions inside the carrying case because it takes some getting used to as far as operation and if you're like me not using it regularly you will need a reminder. It is NOT airline approved. It also cost half as much as the ones sold by the medical suppliers.
Several people commented that it is heavy but it's not heavier than I expected. For a battery to have the capacity that it does, it is the right weight and it's not like I'm carrying it around with me, it stays on my night stand. Used it in my RV when camping without power hookups and it was fantastic!
After an initial charging, I used the ES720 to power my Resmed AirCurve 10 VPAP. After 3 nights use, the battery still had substantial reserves (one LED "bar"). After recharging it, I then used the ES720 to charge my LG 17" laptop while I used it. Still had lots of charge left.
I bought a 12V to 24V DC converter for the AirCurve 10 as suggested by Easylonger to plug into the 12V socket on the ES720. This powers my AirCurve 10 just fine while allowing me to float charge the ES720, as Easylonger promised. So, during severe storm weather, I can sleep without worrying about power outages or having to discharge the battery. I plan to take the ES720 on overnight Amtrak trips in case there's no 120VAC power available.
As noted by others, the LEDs in display do leak light between them. Nevertheless, I can still read the display unambiguously. The buttons require a lot of pressure to activate, but this prevents inadvertent button presses while traveling. It's inconvenient to have to set the voltage to 24V each time I use it with the AirCurve 10, but that's not a deal breaker for me. Besides, when using the external 12V to 24V adapter, it's no longer necessary to set the voltage since I'm only using 12V from the ES720.
The next size smaller Easylonger battery would have worked, but it's worth the extra weight of the ES720
to have at least 3 nights of capacity between charges.
In summary, the ES720 does everything I need and more. I'll post again later if I encounter problems after using the ES720 longer term.
