    • 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

    • One strong battery!! ***updated rating***
This battery is very powerful in a small package!!! Had to use customer service and Cimy was very responsive! For this price you will not find a longer lasting battery. Able to charge multiple devices and also 5v charging. Great buy!! Pros: small package. Easy carry handle Very powerful (will list usage times below) Great packaging with all DC cables needed Multiple voltage settings Easy to use once you figure it out Cons Battery does not function while plugged in to AC outlet. This eliminates the possibility of auto swap over when power goes out. I bought a small alarm for my outlet to wake me if power goes off so I can swap to the battery Video on YouTube shows that you can fly on airline with battery. Clearly states it cannot be taken on airplane when you receive the item. Usage times using Phillips resporonics dreamstation Night 1- 7:45 hrs with humidifier on. 100 to 60% Night 2- 7:45 hrs with humidifier on. 60 to 9% Re-Charged Night 1- 8:00 hrs without humid 100-87% Night 2- 8:25 hrs without humid blu, modem 73% Night 3- 7:00 hrs without humid blue modem 61% Night 4- 7:35 hrs without humid, Bluetooth, modem 48% Night 5- 8:15 hrs without humidifier, Bluetooth, modem 32% ***heated tube with humidity set to 2 was significantly less. Battery lasted 4.5 hours on a full charge. Heat and humidity setting really drain this! Buy regular tube and run dry and you will get a few good nights out of it I do not like sleeping without the humidifier so I stopped after night 5. You get the gist ****UPDATE**** I used this during a trial period for the state listed above. It sits on my nightstand waiting for power outage which we have not had since this review and now the battery will not even power on. When I plug it in it reads 100% charged but will not power on its own or to my machine. Absolute junk. Very disappointed. ... 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
