I love this thing. In fact, I was just telling my wife how much I appreciate this dumb thing, & typed "renogy power bank" into the search bar here to see if they still made it, or if the company was even still around. I'm glad to see both still in tact. I bought this dumb brick over 3 years ago and they still make the same one. That says something. Everyone is impressed by the wireless charging capabilities, it comes (in 2022 anyway) in a nice case with a bunch of charging adapters & stuff, which are also in a nice case. And the performance is perfect for laptop, tablet, phone charging on the go, or during power outages. I also use it while camping inside our little tent trailer to run USB lights & charge stuff as well. It even "fast charges" the new power-hog Samsung phones. Not "super-fast," but still fast. Even "fast wireless charging" on S25 ultra. Pretty impressive for a 2022 unit. Although I use the bigger Jackery-style units as well, this one packs in a backpack or larger laptop bag for a business-on-the-go kinda setup. While I don't have any scientific data to flex, it's plenty suitable for a laptop+multiple phone charges, or to keep essentials running for a weekend camping trip. I don't use CPap or anything so I can't comment on that personally, but I hear people have much better luck with the larger jackery units for that type of use. Anyway it's legit. Legit enough for me to spend the time to type this out on a phone keyboard which I don't love doing. But I had to when this popped up in my search & Amazon reminded me how long I'd had it φ(゜゜)ノ゜ Read more

I use this to power my cpap machine when on the road or camping and charge it up while I'm driving in the car. I had my doubts but it works great. Pretty sure I can get two nights out of it easily with my non-humidified cpap machine. Much cheaper than the cpap manufacturer's solution and useful for more devices. STARLINK MINI UPDATE Just picked up a Starlink Mini and didn’t want to power it with an inverter. Started searching for adapter cables in USBC and cigarette lighter plug but so many reviews said they didn’t work. Went to hook up my CPAP while camping and had totally forgotten about the multi-voltage output and the barrel plug socket. My DC power solution for the Mini was staring me right in the face. The barrel socket is the same size and correct polarity for the Mini. Just set the output voltage to 24 volts and plug the Mini power cable in and you’ll be surfing for hours with juice to spare for a night of CPAP usage. I charge it back up with my MacBookPro USBC charger while I’m driving to my next camp site. Edit & Year of use UPDATE: Still working perfectly! I've also discovered that it charges with solar very easily. I hooked up a folding TopSolar 100w folding panel and it charges it quickly. Not sure it's meant to be charged that way but it works in a pinch. I wake up and connect it to the folding panel with the barrel to barrel dc connection and go exploring. When I get back it's fully charged and ready to go for the evening Starlink Mini use and CPAP power (no humidifier). Plenty of juice! I'm buying a second one to keep in the camper just as a backup. I have been so happy with this power bank that I've recommended it to other cpap campers. No need to die a little each night because you can't power your cpap, this is your solution! Read more

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? Read more
