In 2018, I began BPAP therapy with a ResMed AirCurve 10 device. With an upcoming remote tent camping trip, I looked for a power bank that was portable, compact and lightweight. The Maxoak K5 fit the bill, giving me several nights of power before it required recharging in my vehicles 110-volt outlet. The Bluetti X30 is the next generation in what appears to be the same frame with several improvements over the K5. With a new Lithium battery system, the recharge cycles have increased from 1000 to 2000. It comes with a variety of power cables, all labeled for various compatible device. The LCD backlight turns off in a few seconds with only a very subtle blinking night light along its bottom edge. Start-up has also been simplified. Press the power button for a few seconds to turn on. Plug in the appropriate power cable and the X30 recognizes it and displays the related power on the LCD screen. Press the DC button to direct power to the cable and plug it into the device. Simple! At 95% battery usage, there is a continuous beeping, alerting it is time to recharge the power bank. In testing the X30, I get 4, six-hour nights with the heater/humidity turned off. Because my device double pressures are high (range 12 to 17) it impacts usage hours. A CPAP verses BPAP device, with a single lower pressure will improve usage hours. All in all, The Bluetti X30 is a great, compact, lightweight power bank. If I had any recommendations, the power cables could be much longer. It still requires 110 volts to recharge but if you are camping in a National Park without power access, any ranger station will recharge medical devices. The new travel case is a nice bonus.

I like to keep some form of backup power as I use a cpap. I've had a big car charger battery pack for years now and it is finally dying so I started a search for a replacement that was hopefully smaller and could last more than the one night I was getting with the big battery pack. I found this unit and decided to give it a try as the reviews were pretty good. All I can say is "WOW"! The unit is much smaller than I was thinking it would be and lighter too. Pretty much looks like the little boom boxes we carried around in the 80's. I wasn't expecting much but figured if it went one night I would probably be fine as we usually don't lose power for longer than a few hours unless a hurricane is rolling through (or even just by). As hurricane Debby was on the way, I got this one as it could be delivered same day. It came with a 75% charge and only took a short time to hit 100%. Unit was packaged brilliantly and is made to be very portable. It came with so many connections but after a short look online I knew I was looking for the 12V-5A cord for my older System One cpap. We didn't actually lose power for more than a minute in three different times during Debby so I didn't actually have to rely on it but it would have been no problem if I had. This last whole week I have tested it at night. Filled it to 100%, unplugged the power and used it for five nights in a row! I have the Philips system one machine and my setting is 10. I turned off the humidifier as instructed for longevity and went to sleep each night as usual. I had the machine running almost 9 hours a night for five nights in a row and still had 20% battery life! It basically used 16% a night. I was completely shocked at how small the unit is versus how long it lasted. Frankly, it's incredible! I had no idea I could have had something this small when camping and gone that long. It seemed a little on the expensive side but I can't complain about performance. I also can't talk about how well the battery will maintain it's output but my initial impressions and testing were mind blowing. Very pleased so far!!

I bought this CPAP battery backup because I live on the southeast coast, where hurricanes and severe storms can knock out power for hours—or even days—several times a year. After testing it myself, I’ve calculated that I can get several nights of CPAP use from a single full charge, which gives me great peace of mind. One of the main reasons I chose this model is its pass-through charging feature. This allows me to keep the battery plugged into the wall and my CPAP plugged into the battery. If the power goes out during the night, the battery automatically takes over without any interruption. In fact, during one storm, I didn’t even realize the power had gone out until I woke up the next morning—my CPAP kept running seamlessly. As an added bonus, the battery also has a USB outlet, which is perfect for charging my phone in an outage. If you use a CPAP and live in an area prone to storms or power outages, I highly recommend investing in a battery backup like this. It’s a small price to pay for uninterrupted sleep and peace of mind during emergencies.

This charged up with my generator while camping. It lasted 6 hours on a full charge. I use it to run my CPAP machine. Took about 6 hrs to get full charge on it tho.

Says will run a C-Pap machine 2-5 days. More like 5 hours before you wake up with no air. Took out of box and charged to 100%. Anticipated a good night's sleep. Not happening. Do not purchase for this purpose.
