Not in stock at Fasttech.
I have 3 here and have given 2 more away to my daughter and her husband, they’re great!
They are really nice. I especially like that with a double click of the power button, it’s in the always on mode so it won’t shut down when charging ultra low current draw devices like the Jetbeam Mini 1, etc. You’ll know when you’re in that mode because the 4 charge LED’s will flash one at a time. To exit the always on mode, just single click the power button.
Man these guys are running the competition.
I wonder how this would compare with Anker PowerCore+ 10050mAh QC3.0 power bank.
Just a guess, based on testing 20 powerbanks :
the Xiaomi will score marginally better, as it is a LiPo-cell as opposed to the Anker, which uses 3 18650's (based on it's dimensions and power rating.) LiPo based powerbanks always score a little bit higher in my experience.
I put purchase date labels on mine to keep track of them. So far the one I purchased in May of 2015 is still going strong after extensive use. I’m very impressed with this company.
Interestingly though, Xiaomi’s power banks with QC rating are not officially certified by Qualcomm.
Anker is.
I got the power bank, but it’s not working properly. It doesn’t connect to any device and when I’m charging the power bank, the one dot keeps blinking for few hours and then skips to all 4 dots. When I plug in my phone or any other usb device, nothing happens. I think that the whole pcb is broken. Do you know if I can get that pcb alone anywhere?
Hello,
Thanks for the test.
I would like to know something about how much Quick Charge changes the usuable capacity (charging cycles on mobile phone)? The main idea of mine to have a powerbank is to have maximum times(cycles) %0 to %100 battery charging on mobile phone when you are away from AC 
Mi Powerbank’s capacity is 10,000mAh @ 3.85V so it means if the mobile phone is 3,85V and has 3000mAh battery it can be charged nearly 3.x times but if the mobile phone is 5V and 3000mAh so it can be charged aproximately 2.x times.
So the quiestion is; Quick Charge 2.0 is charging at 9v and Quick Charge 3.0 at 12v and at these rates how many times can we charge a mobile phone which supports Quick Charge with a battery of 5v 3000mAh?
Best Regards
I know this question is several months old but I will explain it quickly anyways if anyone needs to know.
When trying to figure out how many times will a powerbank charge a phone, it is easier to ignore capacity and voltage entirely and focus only in energy. By looking at the closest discharge rate in the chart, take that Wh output rating and divide it into the Wh required to fully charge a phone, that’s how many times it will charge it.
Lets say you have a phone that charges at ~9V 1.5A, and using a power meter you know that it takes 18Wh to fully charge. The xiaomi has a output Wh rating of 34Wh at that charge rate, so it will charge the phone almost 2x times.
Rated capacity is how much it has, output energy is how much you get. This is why discharge tests are important when reviewing power banks.
Thank you for the explanation
No, Quick Charge V2.0 can charge at 5V, 9V or 12V, V3.0 can charge with anything from 3.6V up to 12.0V in 0.2V steps.
Using higher voltage will change the number of charge cycles very little.
Where is the access for the 9 & 12 volt output?
The USB-port... But the powerbank won't output 9 or 12V on it's own, you need something that supports QC2.0 or QC3.0, that 'asks' the powerbank for higher voltages.
There’s a (random) thought: does anybody make an adapter that you can plug into a QC 2.0 / 3.0 supporting USB device and get a selectable 5V / 9V / 12V for a device that doesn’t support QC? A QC to barrel connector adapter, for example? You could run a Li-Ion charger that happens to need a 12V power supply from a QC-supporting powerbank…
Something like this: Test of USB QC2-3-MTK-PE Trigger J7-t
I have also seen a “naked pcb” version on Aliexpress.
Cool, all I have to do is solder a barrel plug to a USB plug and it’s done.
Thank you :+1:
Thanks for the review 
Hi, Guys. I am new here. Great review by the way. I was wondering when the low current mode of this powerbank is activated the max current output gets limited, Like what if i try to slow charge my phone by using this mode, wil it work? When i am no in a rush i rather slow charge my devices to avoid stressing the equipment.
Cheers
Hi, welcome to the forum
When the low current mode is activated it only delays the auto shut off, but output works exactly the same. If you want to slowly charge your phone just use a low quality or very long cable, but I don’t really see the need for that, most phones charges at a safe rate for the batteries.
