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.

This would be the 5th omnicharge product that I have purchased. I have purchased the Omni 20c, the Omni Ultimate, and two Omni mobile 12800s for myself and family. Each has its own purpose for work and travel. The omni 12800s are great, but I needed something that can provide enough charge for a few different devices that I now have to carry. The build quality is sturdy and its slim design allows it to fit in the slip pockets of my main travel bag. So far, I've been able to test all the ports and they all output the expected wattage. The unit heats up a little more than expected so I don't charge any high draw devices inside my bag and usually plug those in when on the table. Capacity is as expected so the battery cells seem to be in good condition. My only real complaint is that the wireless charging pad on the battery is a bit finicky with my phone placement. Once on there it seems to pull a charge efficiently even through my phone case. I did notice that sometimes it stops charging and then restarts itself without me touching the device. I suppose not a big deal. My 12800's seem to have a bit more reliable wireless charging. I don't think i'll rely on the wireless charging pad of the 25600 for overnight charging as I don't want to wake up one morning on 5%. Still a very good product and I hope the wireless charging pad becomes more reliable as this is fast becoming the standard.

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.
