Renogy 72000mAh 266Wh 12v Power Bank with 60W PD, CPAP Battery for Camping, High Capacity Large Camping Power Bank with USB-C DC Wireless Charging & Flashlight, CPAP Battery Backup Power Supply

I've used this for almost 2 years now. What an awesome battery. I can use it to power my resmed 11 cpap for 2-4 nights. I can charge my phone like 13 times. I can charge my laptop like 5-6 times on it. I can charge it with a power supply, or a USB c cable. It takes about a full night to charge. I have also set it up with a 60 watt solar through USB c, and have charged it while camping. The thing is a heavy brick, but it's really compact for how much power you get. The wireless charging on it, is kind of slow, but it works. I don't use the lights on it but it has a pretty bright white and red light. You can't take this on planes because it's too big of a battery. But overall, I have had sooooo much success with this battery. I don't even go out of my way to write long reviews that much, that's how good of a product this was.

I have a ResMed Airsense 10 that I use at a pressure setting of 9, no humidifier (hate the water up my nose). I do Cub Scouts camping with my son and not having a cpap is horrible. I needed a solution. I came close to buying a $700 solar power station, and still might but for other reasons, and then happened on this. I need a max of two nights so I looked at the power and that it can be charged by solar using USB-C, and figured that if it couldnt handle two nights I would just take a foldable solar to top it off. I got it in and believe it came fully charged, but charged it anyway. Ive used it the last two nights and it still has 4 bars, which is 75-100% charged ( the right four bars are for voltage selection). I then checked the comments again and found someone doing the same thing that got over 50 hours use out of it before recharging. With hurricanes and the odd power outage I can also use it as a backup. Ive had one or two nights like that since going on a cpap.Its not magic, its a 266Wh battery, it just happens Im not drawing that much with my cpap. Not heating water for the humidifier likely is the reason.After this last campout Hell finding this is a dream. Having a generator on a campout would be ridiculous. Not that my air mattress etc isnt. So solar was my research target. Bonus, if there are any hikes in the future I wont even need to take the solar panel. I hadnt counted on this but Ill also see if I can power a DC fan or two off of it while using it as cpap power. If the total gives me 2 days Ill be happy. That saves on D batteries. But to be honest its already paid for itself in giving me what looks like about a week of cpap power capability and emergency backup.Thing is rugged, solidly built. Now if I can just take care of the battery through proper maintenance.UpdateSo I'm on my fourth night starting out with 50 percent or two bars. One thing to note is there is a lot of bleed over from one lit led to another unlit led slot. So two fully lit leds can look like 4 with the others lighter. In fact the leds on the left can look like the 24v DC selector led is partially lit. At 50 percent there is no fully lit led next to the fourth power led, and because of this it appears green with bleed over from what ive read is the wireless charging green round light. Also you read power from right to left. So the four leds dedicated to power will show 25 percent if the right most led is lit. 50 if the two on the right are lit. Etc. Again with one led fully lit it bleeds over to the lights left and right of it just enough to make them appear partially lit. It appeared fully charged longer because the 3rd led bleeds over into the fourth as does the green wireless light. If they ever do a new design they should fix both this bleed over and what I think is a usability expectation issue and either Mark the leds or light them left to right. But that could be a culture thing.At the moment this thing is awesome. Or at least it's meeting my desires which is the ability to Use my cpap camping and bonus I don't need to take a solar panel if I'm going for less than 4 or 5 days. I suspect I'll get 5 days out of it, with about 10 hours each night. No in dint get that much sleep. Certainly 4.

If you are looking for a USB power bank, you'll be disappointed. This battery pack is a bit different. It has far fewer USB ports than you would normally expect, they have fewer settings, and most importantly, if you use any of the other types of outputs your use of the USB ports is restricted.This is noteworthy, as it absolutely is possible to destroy electronics that were connected carelessly.But with this warning out of the way, this is an amazing and rather unique product. The battery capacity far exceeds what TSA regulations allow on a plane, but that's exactly what makes it perfect for week long back country trips. Weight is passable considering the capacity. And the variety (but not the number!) of connections is amazing.While not highlighted in the product description, this power bank comes with a patch cable that has barrel connectors on both ends, and it even ships with a good selection of adapter plugs that connect to this patch cable. This means, there is a very good chance, you'll be able to plug in most of your DC-powered devices. And if you have an incompatible socket, suitable thirdparty adapters are available inexpensively all over Amazon. But most people won't even need them.The power bank can either output common USB-C voltages if using a USB-C cable and/or USB-C PD trigger (e.g. 5, 9, 15, 20V). But it can also manually be configured to output a choice of voltages between 12V and 24V DC (namely 12, 16.5, 20 or 24V). This means, many common devices will simply work out of the box. Just be extra careful when selecting the voltage to not exceed the maximum that your device can handle. And don't plug anything into any of the other outputs that are wired in parallel (e.g. don't use barrel connector, USB-C and cigarette lighter simultaneously).Also, and this is important to know, with this power bank the positive pole is always in the center of the barrel connector. This is the most common configuration for consumer devices, but some small number will make the center negative. If you plug those into the power bank, they'll instantly get destroyed. So, again, carefully check the specification.Overall, this is an extremely useful and powerful tool that doesn't really have many alternatives on the market. But with all these powerful features comes the warning to watch what you're doing. For instance, when plugging in a pricey CPAP device, instead of using the built-in barrel connector and manually configuring the voltage, I recommend getting a USB-C PD trigger cable instead. Look for ASIN B08NTTK8S9. I don't trust myself to push the right buttons in the middle of the night, and making a mistake can easily fry the CPAP by giving it too much voltage.Another advantage of using a trigger cable is that it prevents the auto-poweroff feature of the battery. Some reviewers were complaining that they couldn't connect devices that draw very little power (e.g. a CPAP that is in standby mode), but a trigger cable avoids that issue.

I purchased this recently so this review is based on using this battery for only 3 days. I bought this battery for use with my CPAP machine when we are remote camping. When the battery arrived it was partially charged so I charged it fully. The battery kept my CPAP machine running for 2, 9 hour nights the 3rd night the battery died midway through the night. I did not use the humidifier on my CPAP machine. I was hoping that the battery would stay charged for several more nights, but 2 is passable.
