Xiaomi zMI qB810 per 10,000 mAh Review

A quick overview of Xiaomi’s 10,000 mAh small mobile battery – design, functionality, speed of charging of the paperback and smartphone.

Portable batteries have long and firmly entered the lives of experienced users of smartphones and other mobile electronics. After all, in the vast majority of cases, devices are discharged very quickly, which forces everyone to live “from socket to socket.”

Power banks partially smooth this problem, allowing you to charge your smartphone right on the way, in your pocket or bag, and have become an absolutely indispensable gadget in business trips and travel.

It would seem that the problem is solved – take a quality Power Bank more, and your autonomy increases many times. And such a power bank has been found – it’s Xiaomi mi Aura 20000, which is not expensive, has a decent capacity and interesting functionality.

However, the reverse side of the medal becomes quite a large size and weight. Of course, it’s not a problem when you go somewhere with a backpack. But it often happens that you need to run out of the house light quickly, and the smartphone is always almost discharged. Some people prefer to spend their whole lives light, not burdening themselves with unnecessary weight.

In this case, carrying in the pocket of a large power bank is not quite handy, and many begin to look for a second power bank more compact. And then comes to the rescue again a wonderful high-quality brand Xiaomi with its compact model zMI qB810.

Packaging and trim

The Power Bank Xiaomi is packed into a small, neat but sturdy box with a capacity of 10,000 mAh and an emphasis on the fact that it is an external high-speed battery.

On the backside is the model of the “B810” and the specifications, which we will analyze a little below.

The package includes a handy short USB/Type-C cable to charge both the power bank and the devices, as well as a brief instruction.

The cable is 30 cm long, and you can also use any of your Micro-USB or Type-C cables.


2. Specifications

Thanks to the light modern lithium-polymer battery from a well-known quality manufacturer, the weight of the power bank are slightly more than the average weight of a modern smartphone (140 grams).

As with all power banks, the capacity of the internal battery (10,000 mAh) is indicated, and this does not mean that you will be able to charge the smartphone with a 2500 mAh battery 4 times. Since the battery voltage is 3.85 B and converted to 5.1 B on the way out, the loss gives about 6900 mph on the way out. Divide this value by the battery capacity of your smartphone and find out how many times you can charge it.

This Power Bank only supports the fast charging technology of the quick Charge 2.0, both for charging the power bank itself and devices. This is typical of such a capacity, but the EMI can successfully charge devices with zC 3.0, just a little slower (in the mode of zC 2.0).

The power bank is charged through the Micro-USB or Type-C port, and the devices are charged via a full-size USB-A. Microcurrent charging is also supported, recommended for gadgets with small batteries – miniature headphones, smartwatches, etc.


Design and size

Xiaomi is made of high-quality non-beating ABS plastic. On the sides, it is matte, but the top and bottom glossy with a beautiful texture.

It looks very cool, but it is better to wear a power bank in a soft bag because of the branding of gloss.

It is very compact and thin, comparable in size with modern smartphones, lying almost on a par with 5.5-inch models.

This makes it easy to hold it in your hands or pocket while charging your smartphone.



On one of the ends are all connectors and charge indicators that do not glow while the power bank is in sleep mode.

Inactive condition, the white indicators in front show the balance of the charge in a 25% increment and inform the user in charging the power bank and devices.

The blue light on the corner glows when you activate the fast charging, and the multifunctional button next to it gives the following features:

  • Short press to standby – show the rest of the charge
  • Short press in charge mode – turning on/disabling fast charging
  • Double press in charge mode – charge with a small current

In general, there is everything you need – the ability to charge devices with fast charging, with the usual charging and small current to choose the user.


Charging speed

From charging with the support of zC 2.0 or 3.0, the power bank is charged at 85% in about 2 hours 15 minutes, which is an excellent result. It is then recharged to 100% with a small current for about 1 hour 15 minutes. In this way, it takes 3 hours and 30 minutes to fully charge the EMI qB810.

When charging devices in normal 5B/1A mode, the power bank is enough for about 7 hours of charge. When charging in 5B/2A, it lasts about 3 hours and 20 minutes. When you activate a fast charge 12B/1.2A, it lasts for 2 hours 30 minutes.

Thus, knowing the time of charging of your device and the parameters of your native SU, you can easily estimate how much you will have enough of this power bank. Our tests are easy enough for two full charges of a smartphone with a battery of 3000 mAh.

In addition, there is end-to-end charging – you can charge the power bank from the charger and at the same time a smartphone or gadget from the down bank. Apple’s 5.1B/2A device charging is also supported.



Power Bank Xiaomi has shown itself from the best side – it is well-assembled, stylish looks, has all the necessary charge modes (regular, fast, microcurrent), and high energy conversion efficiency.

But the most important thing is that it is the most compact and light of high-quality power banks of similar capacity, it is the size of a smartphone, and it can be carried with you constantly. The disadvantages can be noted except glossy coating, so I strongly recommend getting a bag, which is also convenient to wear cable.
