About three years ago I broke my back in a training exercise this greatly hindered my ability to get outside and to enjoy the outdoors. I grew up in Northern Alaska and spent most my life camping / hunting. The damage to my back was devastating and left me unable to sleep on the ground without agonizing pain and near paralyzing numbness of my lower extremities. The recovery as you can imagine has been tough to say the least. As with anything that inhibits your ability to workout or exercise you gain weight. I have gained over 60lbs and this has caused my sleep apnea to worsen. To be specific I went from an average pressure of 10 to an average pressure of 16. To be able to get back out on the trail and take my scouts out and let them expectance the out doors I needed to find a way to take my therapy with me. Last year they came out with the Resmed Air Mini.. The expense was great but I knew the size was just what I needed. This year i was able to get one and have used it several times. Now I just needed to be able to power it on the trail. I bought 4 different batteries before I came across the MaxOak K5. Each of the other batteries had issues. one would not update the power remaining in the battery one would only power it up for a couple hours even though it was being used in a DC only configuration and the last two only lasted one night even though both manufacturers stated that they would power my Resmed Air Mini for multiple nights. The K5 has performed marvelously. I started testing it at home in my normal bed. I was able to get 6 full nights rest.. That’s (6nights) at 8.5 hours per night. I was giddy with excitement. Hoping that it wasn’t a ruse I charged up the K5 and slept on it for another 5 nights experiencing about the same percentage use each night as the first 6 nights showed (the only reason this was 5 nights and not another 6 was because we were headed camping on the 6th night so i charged it back up to be ready for the trip). I see roughly 12.5% battery drain each day this would equate to 7 nights of sleep on the battery but anyone that knows how these battery’s work would tell you that the last ~10% is hard for the machine to judge because different cells will discharge differently over the use of the battery so its best to not trust the last 10%. The K5 is a no brainer to charge just plug it in and walk away, the charge time is very reasonable at roughly 5-6hours and the digital display is very easy to read. The instructions were surprisingly clear for the fact that English is not the manufacturers primary language and I had no issue getting the proper voltage selected to power up the Cpap.. I took this on a 6mile hike and powered my Resmed Air Mini for 2 nights on the trail with great reliability. The K5 case is a very rouged plastic with a gasket to prevent water from getting in to the battery. the display is very easy to read and the buttons are very simple to operate. I have now slept on the K5 using the Resmed Air mini for 14 total nights and the battery continues to operate very well.. The unit that i got was missing some of the adapter cables so i contacted MaxOak and they sent a care package out within two days to correct the issue. My hat is off to the guys and gals at MaxOak. I will be purchasing more things from you in the future. I am VERY happy with the K5 and Super happy with their customer service. Thankyou sooo much for bringing the outdoors back into my life.. If anyone has any questions I am more than happy to answer them. This is a great company and a great product.. -Nick V. UPDATE 5/28/2019 I have now taken the MAXOAK K5 battery on 5 separate outtings lasting from 2 to 5 days. I have had no issues with the battery holding a charge or with operation of my RESMED AIR MINI.. Our outtings entale a 3 to 5 mile hike in to the camp site so space and weight are a premimum. The K5 is definatly heavier then I would like it to be but to be honnest the fact that i can get 6 nights of restfull sleep (Roughly 8.5 hrs each night) out of it makes it TOTALY worth it. I had looked at several different batteries before purchasing the K5 and even tried a few out with minimal sucess mostly due to my higher than normal pressure. The pictures from above are after 3 long nights (one night at about 8.5hours and the other two closer to 10hrs each) in the mountins at roughly 3000 feet of elevation. On previous outtings before I had the K5 I would only get a few hours of sleep each day leaving me drained and grumpy. Now I am able to wake up feeling refreshed and quite honnestly not wanting to get out of bed because I am so comfortable and sleep so well.. This has been a life changer. I am happy to answer questions if you have any. But if you are on the fence please just order one you will be happy you did. Nick V. Update 10/31/2019 I have now added another 15 charge and discharge cycles on the K5 and it continues to perform just like day one! I had a few questions for the MAXOAK team about the buttons and different information that their website said verses what the desertcart post said. The personnel at MAXOAK immediately updated the info on their website to correct the discrepancies. They are probably the most responsive company I have dealt with. Cimy is Amazing! He answered my questions and was very helpful finding a power cord for my AirMini. I HIGHLY RECOMMEND THE K5 and THE MAXOAK BRAND! WELL DONE! Review: Worked well until they died, been through 2 of these. - I have had two of these, both worked well at first however both died without being used much. They are only useful if they are fully charged as you have no idea WHEN you will need to use the battery. However it seemed to me keeping them plugged in after charge maybe messed them up. I am unsure. Neither of them were used more then 2-3 times total. So the battery should have lasted much longer. But one day it would just no longer hold a charge. if you do not keep them plugged in, the battery loses it's charge over time, and is a headache should you need them when power goes out. They look good, they traveled well, but in the end You need something dependable these were not. They did not hold charge well when unplugged, and they failed after very few uses. For a CPAP you need a device that can STAY plugged in or hold charge a long time so it's always ready to go. I wanted to like them, but for the price they are miserable, and neither lasted longer then a year. Dissapointed. ## Features - [Wide Compatibility] - This 297Wh CPAP battery backup is compatible with 12V/24V CPAP, including System one 60 & 50 series, Airsense/Aircurve 10, Airsense 11, AirMini, Resmed S9, Dreamstation, HDM Z1 (12V only, not for 15V HDM), Transcend Mini, Airmini(cable for Airsense 10 & Airmini are not included, inquiry seller to buy), and other 12V, 15~18V or 24V CPAP, providing power backup during power outages.

Need for airlines detailing. **Q: is it compatible with Resmed Aircurve 10?** A: YES, COMPATIBLE. It has the same adapter connector with airsense 10. we include the proper dc cable for your aircurve /airsense 10, they use the same cable **Q: What type of battery is this? Is it Lithium metal?** A: This is a Li-Po battery (Lithium Polymer), not Li-On (Lithium Ion). **Q: How do i recharge this battery? i have resmed airsense 10 and have connected the battery to the cpap machine. when i plug in charger to wall outlet** A: The instructions that come with this power bank are very poor so, forgive me if my answer is too detailed but, I'm unsure of what your problem is, so I'll start from scratch. With the Maxoak "battery", you should have received an all-black charging wire with 6 x 2 1/2 inch adapter, labeled "SWITCHING POWER ADAPTER". One end is the plug which goes into a wall outlet and the other end has a small [1/4 inch diameter] adapter with a black ring at the tip. The tip is inserted into the right side of the "battery" where a rubber gasket says OUT5V2.5A IN25.2V3A. Lift the rubber gasket [where the triangular arrow indicates] and you will see a small round hole. Insert the adapter [with the black ring at the tip] into the hole. The battery charge level should read the % charged, without the need to turn the machine on. Once fully charged, remove the charger. There are many adapters included in the box and this can be confusing. The cable that I use has a 1.5 inch red tag wrapped around it and is labeled "DC24v Resmed Airsense 10". [NOTE for other CPAP users: The same adapter works for my "Aircurve 10"]. Plug the small-diameter-end of the adapter FULLY into the left side of the "battery" where it is labeled 24V/6A and plug the wider-diameter adapter into where your CPAP power cable was previously attached. Press and hold the power button until the screen turns on [about 3 seconds]. Press the DC button to confirm the dc voltage [about 1 second]. Press the power button again [1 second]. This last step is very important. Don't forget this final step. Now your CPAP should work. If that doesn't help contact Maxoak customer service; I've found them to be responsive. ## Customer Reviews ### ⭐⭐⭐⭐⭐ BEST Battery on the Market!!!! 6 Nights at an averagepressure of 16 *by N***. on April 29, 2019* I am an Active Duty Navy Chief and Scout Master in Port Orchard, WA.

Dissapointed. ### ⭐⭐⭐⭐⭐ Very Dependable *by H***E on August 13, 2023* I have years of experience with this MaxOak, having bought it in 2019. Use it to power my ResMed S9 model VPAP when van camping on road trips. Works like a charm. However, it is very important to NOT use the VPAP's humidifier feature unless you are willing and able to recharge the MaxOak every day. When I tried to use the humidifier, it killed the battery in about seven hours. But with the humidifier disconnected and the heated hose replaced by a dead one (Slimline) my VPAP, which draws 4 amps/hour, lasts several days. Specifically, I find that it draws down about 2% of 100% full charge for each hour of use. Examples: Starting with a 100% charge, it will have 84% charge left after eight hours of use (100%-(8hrs.x2%)=84%) and 68% after another eight hour night (84%-(8hrs.x2%)=68%) and so on. The info screen on the battery shows what percent of charge remains in the battery at any point. I find this 2%/hour formula holds up very reliably until the remaining charge gets down to about 20%. At that point, it sometimes continues to drain at 2%/hour, and sometimes the bottom falls out and it drains considerably faster, perhaps twice as fast or more. Therefore, I always recharge it at about 25% just to be safe. Admittedly, my MaxOak has a rather comfy existence, riding in a padded container on a shelf in the back of my tricked-out-for-camping Chevyvan, where it is warm and dry and clean. When traveling it never leaves that environment, since I sleep in the van. I charge it as needed using a DC to AC converter plugged into a cigarette lighter as I go down the road. When I am not on a trip, I keep the MaxOak in my house so it is not exposed to extreme hot or cold temperatures inside the parked van. It has never lost one bit of charge even after many months of storage in the house. I highly recommend this product. ## Frequently Bought Together - MAXOAK CPAP Battery Backup CPAP Power Bank Compatible with Airsense 10/Airsense 11/Airmini/Aircurve 10/S9/Dreamstation/System one Z1 Mini Travel Camping Emergency Power DC12/15/24V&USB5V - Aproca Hard Portable Storage Case for MAXOAK/BLUETTI CPAP Battery Backup CPAP Power Bank - KFD 12V 24V Car Charger Vehicle Power Supply 90W for Resmed S10 Series ResMed Airsense 10 Air Sense S10 AirCurve 10 37297 Series CPAP BiPAP Machines,Resmed S10 370001;300W/500W Portable Power Station --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/51552792-other-cpap-model](https://www.desertcart.pl/products/51552792-other-cpap-model) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
