I actually wanted the ZMI no20 (QB826) as was recommended by a 3 year old Reddit thread, but I thought it was silly having to pay over the odds for a power bank with seemingly no difference to any other of this capacity and size besides the ability for it to continually deliver power whilst being plugged in to charge or unplugged from power, thereby acting like a UPS and power filter all in one.After watching a lot of reviews about the ZMI and being very familiar with it's design, I figured that even though the UPS functionality isn't advertised here, it must have the same or very similar internals as it looks identical to the ZMI, so I assume it's just white labeled. As far as I can tell, they're functionally identical.I have the output from a 65W UGREEN USB C mains DC adapter into input/output 2 (max 65W in) and have the input/output 1 (max 120W out I think) plugged into a USB C power delivery trigger set at 20V, pulling around 100W at peak loads and around 10W idling most of the time.The trigger is plugged into a bunch of DC-DC converters essentially turning it into something of a multi output DC power supply, which powers a home server mini PC, a 3.5" HDD enclosure, a small switch, a 4G router, a raspberry pi, a bunch of usb peripherals, some homemade stuff on breadboards. They all work great from this thing, it's perfect for my needs. It's a briefly powercut resistant server setup. It's a single point of failure for my setup, but it's great.Haven't experienced any problems, and works better than the UGREEN power bank I was using before, which actually just died on me, presumably from my very niche (and arguably incorrect) use case for it.Will update if necessary!

Good product. Happy with the order

The media could not be loaded. We charged this up and took it on a recent camping trip for a few days.It’s not small, and is weighty, but feels solid and robust.We used it for iPhones and a Nintendo Switch camping - and although I tried to keep track of what it charged, with kids it’s not that easy lol.There is a display on the side displaying % left - but it charges iPhones loads of times. And topped up my son’s Switch console.Can charge several devices as well at the same time - which is a handy thing especially when camping.You can double click the button on the side to put it in low current mode too.Took about 3 hours to initially charge the pack up as it comes with no charge.Would recommend - seems to do what it says on the tin.Would recommend

Excellent performance. Charges quickly. Runs a Starlink Mini 4 Hours on a cold January night pulling an average of 20W. I’m quite impressed with that. 25000 is about 95W so it theoretically should run almost 5hrs but it would need to be 100% efficient and I doubt any power packs are much more than 80%. More compact and cheaper than the Anker units of same size. Nicely packaged and a seems high quality.

This is my second power bank (different brands). It has a a good capacity and can charge multiple devices at once, there is also a display which tells you how much power is left in it - although I wish this wouldn't flash! All pretty similar to my other bank.The difference with this one is it has the ability to still provide power for something that doesn't use much power when on. This is invaluable when you have a night light, for example. I have one of those night light star, aura projector lights for my sons room and sometimes I leave it on the lowest light setting but where it is USB powered and I don't have it plugged into the mains my other power bank doesn't recognise the small draw on power and so turns off but not this one, press the button and the light stays on, hurrah!It's heavy, but good capacity power banks are so it's not a problem.

I am not an expert in battery charging but all I know is that this power bank is very different to the ones that I currently have.Yes, this one has one obvious difference to my existing power banks in that it has the ability to fast charge laptops and mobiles.The other huge benefit of the wattage of this bank is the ability to charge many mobile phones at the same time. This is something that my current banks cannot do so when we are out and about for the whole day as a family when we can easily charge phones and the kids cameras all at the same time. The may sound not too important but when someone's phone is out of batter or the kids cannot take a photo due to the camera having no more battery charge, then this avoids many of these scenarios.I am going to be honest with this review in that I would not spend this amount of money on a power bank if it were not for the Vine review program. Having got this and used it, I fond it has soo many benefits but for me it is almost threes times the cost of my current power banks which I appreciate cannot really fast charge a laptop.I am rating this five stars as I think it is very good product and well built power bank and if if you have the money then I think it does add value to your life with keeping portable tech charged no matter where you are.
