EASYLONGERCPAP Battery Backup Power Supply ES960, 297.6Wh Battery for AirSense 11, AirCurve 11, AirMini, AirSense 10, AirCurve 10, DreamStation/ 2, etc. Emergency Power for Camping Outdoors

I was able to use my Airsense 11 for about 2.5 days running my CPAP and charging my phone. It's convenient that all the cords to plug in your CPAP come with it and setup wasn't to difficult. You can plug in a cigarette 12v adapter without changing settings which I bought as a backup if the supplied cord or outlet fails. Haven't had any issues and the quality seems great for the money. A nice backup for power outages and camping, great product 👍

I used this for about 6 weeks out at our hunting camp. I would charge this on the inverter generator that powers our camp in the evening time during dinner and the BS sessions before bed. We run LED light bulbs and 12V battery charger as well as some chargers for phones and radios. Plugging this EASYLONGER battery in didn't change the strain on the idling inverter and it would be charged after a single nights use in about 35 minutes. I went a couple of night s a few times just because I never saw this below the last bar charging indicating it still held over 75% battery capacity from one night. The times I did 2 nights without charging - it would flash 2 bars down for about 10 seconds and then back to the last bar charging for about another 35-40 minutes. I only did 3 nights on it once and it only took just over an hour to fully charge again. Dead quiet running the AirSense 11. Worked flawlessly. I decided to go this route as I was just diagnosed with mild SA. Also because my uncle who hunts with us has SA and chose to do the marine deep cycle battery to a DC-AC inverter to run his machine and only gets 1 night on it and occasionally doesn't make it the full night. This thing was rather compact and extremely easy to use with being able to select 24v output to the AirSense 11. Didn't have to run wires into the camp from the battery outside and inverter running all night. The only noise I had was the air coming from the machine itself. I couldn't find a way to shut off the constant display which I would have liked to do as I am not a fan of glowing screen light but I would just turn it around and lean it up against the wall so it wasn't blaring light across the camp. Worked as good as being home hooked to a wall plug - never had a problem and it didn't leave me stranded. Had to buy it for the yearly hunting trip but now it is the off season year round back-up for power outages at the house. I put it through some paces over the first 6 weeks since I bought it. Uncle was impressed with the simplicity and capability of this so much he is ordering one for the same reasons as well. No regrets ..... So far...... So good.

Works well! Used it two consecutive nights when our power was turned of by SDG&E (those crooks) and it worked well and still had enough charge for another night if needed.And it has a very bright light so we were able to use that to get around on the darkness of our home.If your looking for a portable option for your CPAP this is a great option!

Very sturdy, well-built Lithium Iron Phosphate (LiFePO4) battery pack. This unit has an adjustable DC outlet (5.5mm x 2.1mm) which can be set at 12v, 16, 20, and 24v. The ResMed AirSense 10 runs at 24v, and this unit comes with dedicated patch cables to use the DC out barrel connector to connect to an AirSense 9, 10, or 11, as well as a Phillips CPAP. Additionally, it also has two 12v/15A cigarette lighter outlets for powering any of your 12v travel adapters.Also has 2 USB A outlets to charge earbuds or anything else needing 5V (18W max) USB A ports.There is a USB C port with PD regulation for both in and out (but it can't be used with the DC output). You can charge this battery pack using a USB Type C charger with PD (65W will work, but using the max 100W standard works best using the 20v/5amps mode). Make sure you get a true 100W charger though, as smaller multi-port chargers frequently advertise 100+Watt capabilities but a single output may only be 35W at most. Get a single-output USB C charger to ensure a max 20v/5a charge.Here's the weird part... the AC adapter is undersized. It comes with an AC power adapter that outputs 20 v to the battery, and is rated for 3.6 amps. Charging the battery up will heat up that charger within an inch of its life... and it's slower than what the pack is rated for.The fastest charge, and the most energy efficient charge for the LiFePO4 battery is to use the 24v charging option. How? Buy a new AC Power Supply (24 Volt / 6 Amp, 5.5mm x 2.1mm DC Plug). Amazon has these for a few bucks and it allows you to charge at a full 24 volts, letting the battery pull a full 5 amps (80% of what the 6amp supply is rated for so it doesn't cook under continuous hours of use). Just make sure to get the 5.5mmx2.1mm DC barrel connector. This will let you charge at a full 120 watts safely and with the least amount of wasted energy.So your charging options are:1) 24v/6a AC Power Supply (120W, 24v/5amp charging over the 5.5mmx2.1mm DC input).2) 20v/5a USB Type C PD charger (100W, 20v/5amp charging over the USB C input).3) The included 20v/3.7a AC power supply (72W charging over the 5.5mmx2.1mm DC input).As for outputs, the best solution is the DC to CPAP patch cable(s) included with the unit. Make sure to adjust your output voltage first. Alternatively you "can" use a 12v cigarette lighter travel adapter for your CPAP using one of the battery pack's 12v/15a outputs, but the patch cables are more efficient at bumping up the voltage to what you need.On a full charge (4 bars), I ran my ResMed AirSense 10 (24v input) AND the humidifier, AND the heated tubing for TWO nights of 8 hours sleep. I use a setting of 9 to 15psi which is pretty normal or even higher than most users. After the second night it showed 1 bar left, though it may have gotten a 3rd night out of it since the charger picked it up to 2 bars (50%) nearly instantly. If you use a lower setting, or skip the heated tubing 3 nights without a charge should be easy.Here's the trick setup... buy the max AC charger to fill it fastest, then keep a 100W rated USB C cable with it as a backup for any USB charger. It ALSO can be charged from any DC input up to 24v... which includes a solar panel: If you get a 100 to 120W solar panel that outputs between 12 and 24 volts you can charge it during the day when off-grid.If you want to use this as a UPS for battery backup during a power outage, using the AC charger to the DC input, you CAN then use the 12v cigarette lighter socket output with a 12v travel charger for your CPAP (available separate). The USB charger and any DC output can not be used at the same time... but DC in and out CAN be used. Buy a 12v socket CPAP travel charger, and a 24v/6a power adapter with 5.5mmx2.1mm DC connector and you're set.
