I bought this so that I could camp at a four-day festival. I did a test at home and used it for four consecutive nights without any problems, and after the test was successful I used it for another four nights in a tent at a music festival. It worked fine and still showed 4/5 cells of charge on the battery indicator after four days. I used it to provide 12V for my Phillips Dream Station 2. I am very happy with this purchase, especially as I got a $30 voucher, so it was worth it!

Giving three stars just because of the case, as pictured is worn looking and the zippered pocket zipper does not work. Other than the case so far I have had no issues with it. Took it camping and ran my Resmed Airsense 11 CPAP machine on it with the humidifier two nights and it only dropped down one bar on the charge indicator. Came back from camping and we had a weather even two days later and I used it again with my CPAP machine and it still has battery life left. Charged phones and flashlights with it as well, and I'm confident there is at least one or two more nights left for running my CPAP.

I have a different back up battery that I used for my CPAP while camping and it only lasted 6 hours.
So I purchased this battery and decided to test it out on my Resmed Airsense 10 to see how long it would last before taking it camping. I got 2.5 nights of run time or about 20 hours. Not bad for using with my 24v CPAP. And I can charge this one with a solar panel to get more run time. Hoping to get 3-4 days while camping. Great product! Love the lights too and included cables too. Much easier to use.
P
Although this CPAP battery is bigger and heavier than I would like, it works great. Using my Resmed AirSense 11 set at 13 PSI with all the comfort features on, it lasts 7.5 hours. When I turn off the heating tube ("tube temp") leaving everything else on, I can get two long nights out of the battery; maybe three short nights if I was careful. Also the battery's cellphone charging pad is pretty cool; it is slow charging but nice to have nonetheless. In summary, the ES960 is good for camping--but too heavy for backpack camping--good for power outages, and for other emergency DC power needs.
C
Went canoe camping and this unit pas able to power my CPAP for 4 full nights on a single charge at 17 cm H2O. I paired it with a solar (80w) pannel and had plenty of spare power for phones a computer.
D
Customer support is excellent. My ES960 works great for CPAP use for multiple nights. The first unit would not charge up again after running out for a period of time. Zeno shipped me a new unit which is now working great. I really appreciate this level of customer service. I use and charge the battery every month now. Love this unit !

I ordered this for my husband’s CPAP. When it came, we tried to charge it, and it was dead. Wouldn’t even begin to charge. We contacted Easylonger, and they sent a replacement immediately, no questions asked. Very good, responsive service. The new one is working great.

I have used this Power supply for camping while on motorcycle rides. I powers my CPAP and charges my phone. 3 days so far without needing a charge. The next trip will test its limits, and mine.

The only downside is not being able to ship it to Jamaica because of the airplane limit but other than that the capcity is amazing. Very useful and easily connects to the solar panel. Great battery life.

My battery originally worked well, but stopped charging within the warranty period. I received prompt and courteous customer support and a replacement battery, which is working.

This battery powered my cpap for 5 nights multiple times ( no heated tube or humidity) for about 18 months then it just went dead and would not charge. I contacted the company by email. I received a response in less than 48 hrs asking for my order number.In about 2 weeks I received a replacement. Very straight forward and professional customer service.

This is a fantastic backup battery for a CPAP. It comes with all of the cords and a really nice carrying case. It charges quickly and holds quite a lot of battery for the size. It works very well and as an added bonus can work as a backup charger for your phone in a pinch as it has USB ports. Value wise, I'd say it's a good one. You're getting reliability and a power source for when powers out at a very good price. That's worth its weight in gold.
J
Incredible CPAP battery for the essential workers and first responders. Extremely versatile and mobile with long battery life and reliability. From camping to extended working conditions. This battery will keep your CPAP running for days (air mini - 7 days before needing charged). Customer service is top notch. Very responsive and attentive to their customers. Quick to respond to make sure the customer is taken care of.

This is the first CPAP battery backup I have used that truly feels practical for camping and road trips. I tested it overnight with my ResMed AirSense 11 during winter conditions, and it performed flawlessly. It powered all CPAP functions throughout the night with plenty of battery capacity remaining in the morning.Even with only a single overnight test so far, the performance was reassuring. Power delivery was stable and consistent, which is critical for CPAP use. There were no interruptions, drops, or warning indicators, and it handled the load comfortably.One very important thing to understand before buying is that this battery exceeds airline limits for both carry on and checked baggage. It cannot be flown. Personally, I am fine with that tradeoff because achieving airline compliance would significantly reduce capacity and runtime. As long as you view this as a solution for camping, road trips, or emergency home backup, it excels in that role.I would especially recommend this for RV camping where campground power can be inconsistent or unreliable. Using this as an inline power source provides peace of mind and ensures uninterrupted therapy throughout the night.Overall, this is a well designed high capacity CPAP battery that delivers dependable power where it matters most. If your use case is car travel, camping, or backup power at home, this is an excellent option.

This CPAP battery is great to have around. Having the assurance that I can sleep all night using my CPAP is comforting, and with ample battery capacity, I can also charge my electronic devices, so I am not without.We were getting a winter storm on the day the battery was delivered and fortunately I did get the opportunity to top off the battery to 100%, just before the power went out. I hooked up the battery to my Airsense 11, with the included connectors, and went to sleep. The battery ran my machine with humidifier all night, and had almost 50% battery left, so I am confident that it will last at least two complete nights, if not longer without using the heated parts. I have read that some low wattage machines can run for many nights using this.This also has a really cool amber and clear light on the end. A long, or double click on the power button lets you select which setting you prefer. The lights are pleasing to the eye, bright, and can be used as a room light too.It has many ports and connectors, and can be used for charging many items, such as phones, flashlights, and will power 12 Volts through either of its two ports.It is kind of like a built in transfer, as you can charge it, and run it using different connectors, however it's not a dedicated pass through automatic transfer switch type device, as it is using the battery power, however with up to 3000 cycles, it isn't a factor for me.It would be great for camping, sleeping in the backyard tent with the kids, spending a few nights car camping, etc. It is large and on the heavy side, however not as large as a battery type generator. I expected some heft for a battery that can deliver this performance. It has a convenient built in carry strap that makes it easy to take along. The batteries are LiFeP04, which are awesome, no memory effect, can handle deep discharges and many cycles. Voltage selections are 12, 16.5, 20 and 24 volts output.I am very happy to have this for my use. The quality is great! I have several other EasyLonger products, including one of the smaller CPAP batteries, however I wanted a larger battery that I know can run my CPAP machine with the humidifier all night, as well as charge/run other devices. It has a great digital display and is easy to set up and use. It also has a spot for wireless charging, so when the power was out, I also put my iphone on top, and it immediately started charging through the thick otterbox case.This is a five star product, and with it including the multiple cables for a variety of CPAP machines, this is a clear winner for me.
