EASYLONGER ES400 AIR CPAP Battery, 40000mAh/148Wh CPAP Battery Pack for Camping, 12V 24V CPAP Power Supply, CPAP Battery for ResMed AirMini/AirSense 10/ AirSense 11/ AirCurve 10/ Philips DreamStation

I purchased this to provide power for dream station cpap on a flight. I wondered, would it last the night? Well it's so far on night 3 and has also powered the cpap in the day, just for the hell of it :) superb product if the battery keeps its charge over time. Oh, the cable included for the dream station works great.

I purchased this in preparation for a camping trip abroad next year. It was delivered on time, in very nice packaging with a carry case included. Once delivered I fully charged to test with my Philips Dreamstation to see A) would it last a full night and if so B) How long would it last on a full charge. The battery indicator is in the form of 5 bars (so approxiately 20% per bar). I was amazed to see on waking up after the first night (7 hours & 22 mins use) that it still had all 5 bars showing and therefore I'm guessing had used less than 20%. Important to note that I don't use any heating or humidifier, which I would guess would increase consumption significantly. After night 2 (7 hours & 57 mins use) it had 3 bars remaining, so I risked a 3rd night (7 hours & 12 mins use) and it still had a bar indicating on the battery the next morning. I'm not going to risk a 4th night, mainly because I should have access to charge each day when I'm away, so have tested to a worst case scenario for me and happy to report it passed with flying colours. Over 22 and a half hours use, with charge still left in the device. I'm a big fan of companies that under promise and over deliver rather than the other way around and Easylonger fall in to this category based on this experience and will definitely look at other products. If you're a CPAP user who may have the odd night where you don't have access to power, this is a great bit of kit and will come in handy.

Works well. Lasts for 2-3 nights on one full charge.Comes with a selection of leads to suit various machines.Storage case could be bigger to store the various cables ( I have them in a separate bag that I already had)

Bought this to use with a Philips Dreamstation 12v unit. The leads that come with it fitted my machine well (it comes with 3 versions, can’t comment on the other 2).I tested it after I charged it and it was on for approx 16 hours 😱 I used it again the next day and in total it was approx 26 hours that it lasted .Way longer than what the info says and I’m very pleased with it. Hopefully it will last for a long time and I may get the car charger attachment that allows you to use it like an ups should your power cut out one night.

Nice and compact ,wanted it for off grid usage works well. Only dislike was really difficult to work out what charger I needed for car cigarette to charge battery ( not Cpap)

Coal airsense 10 gave 4 evening usage on a single charge perfect for mobile use

I bought this to use on a camping holidaywoth my Airsense 10 The voltage selection and cables provided made operating my CPAP.I got about 10 hours out of a charge, so not enough for two nights use without a charge. As long as you have access to charging during the day this works well. For a longer self-sufficient trip it might be wise to get a bigger battery capacity.

I have purchased this as I need to use my cpac machine on two flights to Canada with Canada air.Unfortunatly despite the ease of the battery it is massively insufficient to run a cpac machine with or without a humidifier. This i think is because of the settings on each machine for air pressure. At best my battery lasted 3 hours with the humidifier in place and 4 without.A very different story to the promotional video they show on their website.
