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.

Best battery ever. I ordered this based on reviews because I couldn't afford the one my brother has, exp pro lithium, that gives him 3 nights on his CPAP.My Jackery 240 only gives me 2 nights.So, I am currently using this Renogy with the DC adaptor for my Resmed 10. So far, I have 35 hours and not one blinking light!!I started with a full charge. I forgot to time the charging to full, but will next time.I would not believe this if I weren't doing it myself. I was going to wait to review once I had the total use hours. But, it seems that will be a while. So, I'll update this review when I do.So far...perfect!! It is bigger and heavier than the picture looks, but nearly identical to my brother's exp pro lithium.It is actually 9x8x2 and 3.3lbs.I am thrilled with its output!!So, I actually got 49 hours using my Resmed 10 that pulls 90 watts. Fabulous!In recharging, it took 8 hours, from dead to full.The only problem has been with the LED lights indicators. The first light, of four, went out after three days of use. I'm thinking yahoo, I'll get weeks out of this charger! But, the fifth day, it merely quit. All the lights were out and the charger drained. No sequencing through each light. Ugh.The sequence is suppose to be:1st LED blinks, the power level is below 25%2nd blinks = 25%-50%3rd blinks =50-75%4th blinks is 75-99%And mine reads right to left, not left to right as the manual states.But, I called Renogy and got some excellent customer service and the techs will evaluate the problem and get back to me in 24-48 hours. So, well see. I'll update when they do.Okay, here is their reply:"Upon checking, the LED light you are seeing when charging is quite normal.However, for the DC LED light, you should be seeing red light and not blue (it is still considered normal if it seems that the blue and red light are mixing on the 24V DC LED indicator)If the DC LED lights don't really light up, you may file a warranty claim with Amazon since the unit is still within the 30-day period from the date of purchase."Ugh, so I'll have Amazon replace it and how the next ones lights work...Okay, it's replaced, and I'm still having issues with the lights. The manufacturer has discontinued this model and told me they would give me a refund, or I could return it to Amazon.I'm torn as what to do. It is excellent for using my CPAP, the lighting isn't that big of a deal now that I know how many hours I can get. But, I'm concerned if the lights don't work, what else may not. It's the only one I found in that price range. Idon't want to send yet another one back to Amazon and hope i get one that works! Ugh. What to do?

I am writing this review to correct some of the incorrect reviews stating this battery does not work with the Resmed AirMini. I read those reviews and decided to purchase and find my own conclusions about the battery.The AirMini runs 5 nights for me on a full charge of the battery. You must use the 12v regulated power port (the small round port) NOT the cigarette lighter output. This requires an adapter which you can find here on Amazon. https://www.amazon.com/gp/aw/d/B07QZL17W9?psc=1&ref=ppx_pop_mob_b_asin_title If you plug your AirMini directly into the cigarette lighter output port, your CCAP will likely shut off mid-way through your night. This is because the cigarette lighter port is directly connected to the battery without any regulation. At some point, the voltage will drop below the voltage threshold the AirMini requires.Using the regulated 12v power, the AirMini has lasted me 5 nights of uninterrupted sleep. This number depends on your CPAP settings, sleep hours, etc. One additional note, the battery regulated power will automatically shut off if no power is being drawn. So, you must turn the regulated power on, then immediately turn on your AirMini, or any other device you are using on regulated power. When you turn your device off, the regulated power will also shut off after a short waiting period. I assume this is to conserve battery capacity. Smart.I wish Renogy sold the same battery with half the capacity. I use this battery for kayak camping and rarely use it more than 2-3 nights. So, the lighter weight and less volume would be appreciated. I also think it was a missed opportunity by Renogy leaving out the DC 5.5mm to cigarette lighter adapter. They have likely missed a swath of AirMini customers that didn’t purchase due to the reviews.Love the wireless charging, flashlight/floodlight, overall functionality, the supplied all in one cord and and adapters, and durability. Well designed and looks well made.

I use this for CPAP machine when camping. So far it has performed well and lasts for four nights when no heaters are used. Otherwise two nights. One draw back is that when battery is in its' case it is possible to turn on the light without knowing it and run down the battery. I like the case to protect battery when traveling and it is packed.
