Omni Mobile 25600mah 25600 Laptop Power Bank, Universal Charger for All Devices, Fast Charging DC, USB-C & QC 3.0 Ports, Wireless Charging, Travel-Friendly Power Solution

It looks and feels solid. I've played with it some, but haven't put it under much stress--that'll be a few months down the road on a trip where it'll get cycled daily for a week. I'll post back if there are any problems with it at that time.But, for now, there are a few things I really like. First, it's flexible with respect to charging: it will charge via the DC port (5.5x2.1mm barrel connector) at 45W max from 5V-30V. For my use, that's great as I can use an AC adapter from another item I always take on trips. I can also use a 12v plug in my car...or even a USB-A power adapter running at 5V. It can also charge via USB-C ports at a max of 40W....I don't use USB-C much right now, but it'll be useful in the future. I charged it via the USB-C port with the included USB-A to USB-C cable and it worked fine (...it took forever because I used a cheap battery pack with only USB-A outputs running at 5v/2.1a. But it charged just fine.).I also like the adjustable output on the DC port. You turn this pack on with a long press on the power key. The front lights come on to show state of charge (apparently approximately 25% per light). Then double press the power key followed by single presses to select the DC port output voltage. Once you select a voltage, the unit alternates several times between telling you the state of charge and the voltage selected using the lights. Then it goes back to the lights showing you only the state of charge.The only downside is some inconsistency in the user guide (e.g. at one point, it says the DC Port input is 5V-30V up to 2A....in another place, it says DC Port input is 4.5V-36V up to 3A. Both locations in the manual say 45W max. Customer service got back to me within a couple of days and said 4.5V-36V is the input range).I know some don't like that it does not come with a USB-C charger. It'd be nice to have a charger included, but the price would have to go up. I think it's better to have no charger and a lower price. It does come with USB-C to USB-C and USB-A to USB-C cables.Overall, very happy with it thus far.

I bought RedMed AirMini CPAP a year ago for my business travel. Since then, It has been a "must" gear when I go to Asia. The only problem is I can't use it for a long flight. I started looking for a solution online. The most of battery pack designed for CPAP are all above $300. On the other hand, It is hard to find regular battery pack offers DC output up to 24V with decent power rate. The second best option is those products with AC output. But that also means I have to carry an AC adapter onboard airplane. Moreover, the AC adapter also takes some juice off when doing power conversion. When traveling, I want to pack as light as possible therefore bringing an extra AC adaptor just for the battery pack is also out of question. Until I found the Omni Mobile 25600mAh. It comes with DC 5.5x2.1 power jacket. All I need to do is to buy a DC adapter power cable ( $29.00) for AirMini. Now I have a perfect solution – I spend less than $180 (with tax and shipping) to turn on AirMini onboard airplanes without carrying AC adaptor. This unit offers almost the same power capacity ( 92Wh vs. 95Wh) at the exact same weight but $160 less to a similar product. I made a mockup model for a battery pack designed just for AirMini to compare the size in between two products. You can judge by yourself. Best of all, it can be recharged with any standard USB AC charger with USB-A to USB-C cable (come with the unit). I actually charge it with my Lenovo ThinkPad P52s AC adaptor which comes with USB-C PD port. As a battery pack, it has full features such as USB-A QC-3 port x2, USB-C, and wireless charger. Even within all OmniCharge products, I think Omni Mobile 25600mAh is the best product that balances the power capacity, features for CPAP application and price. With its DC output, there is no reason it can't work with other CPAP models running at either 12V DC or 24V DC. All you need to do is to find the proper DC power adapter cable ( from 5.5 x2.1 male to your machine's power receptacle) I hope this info helps people who are also looking for CPAP battery solution

My job recently transitioned to being 100% remote with the odd exception where one might need to come into the office for something. I've been re-thinking the tech that I use in life and adjusting accordingly. My fiance who is a teacher of course has time off in the summer, but me still having to work would make taking vacations difficult. Today, my fiance went around to his students' homes along with the rest of the teachers to do a graduation parade. Being able to work from home, I tagged along for the day and enjoyed the sunlight while continuing to plug away on my laptop, using iPhone tethered over USB to connect to a Citrix VDI session with a 1440p display cranked up to full brightness to be able to see in the sunlight. I charged my ThinkPad X1C5 which was already fully charged with USB-PD (not the DC output). As soon as we left home at 9:15, I plugged my laptop into the bank to keep the battery charged. Got home around 2pm, 5 hours later and the battery still says that it's half full and my laptop battery is still fully charged. For me, this completely fulfilled my expectations. The reason for 4/5 stars is that I was completely unable to get wireless charging to work. I read reviews that said that it was finnicky at best. I've tried my personal iPhone XS Max, my fiance's XS, and my work iPhone 8. I didn't get any attempts to charge. I had no intention of using this wirelessly as my intended use is mainly for in the car and didn't reach out to customer service, but everything else is working just as I would have hoped. Seemingly rock solid device if you don't plan on using the wireless charging.

Usb c stopped working after some time & will no charge anymore
