    • BEST Battery on the Market!!!! 6 Nights at an averagepressure of 16

Review Image by Nick V. Nick V.
I am an Active Duty Navy Chief and Scout Master in Port Orchard, WA. 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 Amazon 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! ... show more

    • Very Dependable
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. ... show more

    • Great battery pack.
This is a great battery. I have an airsense 10. I have been looking for a battery to use while I camp. I bought a different battery from a different manufacturer that was supposed to last 1-3 nights and it had only lasted 4 hours. I only need it to last one night as I have a generator to charge it during the day. I returned the previous battery and bought this one. It works great! I did a two night test both nights I started with a full charge. After 7.5 hours of sleep the first night this battery still had a 50% charge. The second night I only slept for 6.5 hours and it still had a 68% charge left on it. Both nights I had the humidity and heat turned off. I love that I can leave this battery plugged into my cpap and turn the battery off so the cpap does not drain the battery until I turn the battery on for use. I highly recommend this battery. ... show more

    • with humidifier turned off, it is great for powering cpap.
Bought this for semi-annual camping trips of 3-4 days each. I tried it out at home this weekend. If you leave the humidifier on your cpap, the battery lasted 5 yours before going dead. I fully recharded the battery (took 6 hours). When I turn off the Humidifier, a full 8 hours of sleep only used 6% of the battery. This will allow me to use it on a 4 night camping trip without recharging. Perfect for my use. ... show more

    • Loved it until I didn't...
The first 2-3 times I took this camping, I was amazed by this battery. Easy setup with my Resmed 10, and it lasted for three 8-hr nights (no humidifier, no heated tube, and pressure set at 10). But by the fourth use I was only getting a little more than two nights. This past weekend (my 6th camping trip with it), it started at 100% and said it had 77% remaining after the first night. But it was somehow down to 0% about halfway through the second night. I'd thankfully brought another (very heavy and bulky) battery with me as a backup. But given the cost, I am disappointed with the huge decrease in capacity (and false meter readings). That said (sigh), I would probably possibly buy it again because there's not much else on the market that can match for size/weight and at least initial capacity. Since I already have one, maybe a second one would (combined) get me through a camping trip even after the second one's capacity reduces. ... show more
