Mi 10400 portable charger. Xiaomi external batteries
My husband and I already once bought a cheap external battery on Aliexpress for 50,000 microamps, with a solar battery, which didn’t really charge anything. Naive! By the way, it was not charged from the sun either.
Therefore, I decided not to save money and buy a good one, Chinese and definitely branded. Because in China there are not only cheap disposable things, but also quite high-quality ones.
I was already familiar with the Xiaomi brand from their wonderful fitness tracker and that’s why I chose it.
I placed an order at the Great Chinese Sale on November 11, 2015 using a coupon and it cost me about 1,300 rubles. Now the price is slightly lower even without sales and coupons. Oh, this unpredictable dollar exchange rate! I bought it. I recommend the seller
For those who don’t want or can’t wait, there is an opportunity to buy this miracle in Russia, look on Yandex.market, but, of course, it’s a little more expensive.
I chose the capacity like this: 5000 microamps seemed not enough to me, and I was toad strangled to buy a battery for 20,000 microamps, so 10,400))) And there was also one for 10,000, and I still didn’t understand which one was more modern.
In total, this is just my phone (3000 microamps) and tablet (7000 microamps), of course, minus losses, I don’t particularly understand this, but I know that all batteries, when charging devices, lose a certain % of charge and this is normal.
Now I absolutely do not regret that I did not take a 20,000 battery, since charging it takes a very long time and it must be quite heavy. Although it will be indispensable for hiking.
My silver friend came to me for about less than a month; he came just before the New Year. And here he is with me.
Packed conscientiously, in a white cardboard box, inside of which there is another one, this time in a light yellow-brown color, so natural, hinting at environmental friendliness. Unfortunately, I threw away the boxes. It seems there were also instructions in Chinese.
The box contains a short cord and the battery itself. It looks very nice: the aluminum body, with the brand name, is quite weighty. On the white side edges on one side there is a power button, diodes showing the battery charge level and micro USB and USB connectors, on the other there is information about the device.
The case, although durable, is susceptible to scratches, so I ordered a case for it.
It charges from zero in 7-8 hours, it’s enough for me to fully charge my tablet and phone by 70%, so I consider the declared capacity to be fair. A 10" tablet (Samsung note n8000) charges slightly faster from a battery than from a wall outlet; a phone (Lg g3) does not have much difference in charging speed.
In operation for more than six months (we use it almost every day), no jambs have been noticed, there has been no drop in capacity yet.
The only thing I need is another micro USB output to charge another device at the same time. And this is a more than worthy product!

Seal of Authenticity
It is very important to buy Xiaomi Mi Power Bank 10400 mAh from the original manufacturer, and not a cheap fake. We are ready to prove the authenticity of our goods - each model has an individual brand.
In the age of the growth of modern technology, being left without communication means wasting a day. And this day may not just be lost, but even quite spoiled for those whose work depends on the Internet or mobile phone.
Prudent people try to purchase additional mobile devices in case the battery runs out on one, so that they can use a backup one.
Xiaomi offers an excellent option to save active users of modern technology. Xiaomi Mi Power Bank 10400 mAh is a backup battery from which you can charge any mobile device and even a laptop. By carrying an external battery, you won't have to look for an outlet to charge your phone. You can charge your device within an hour (this is the maximum) until the battery is full. Many who use the seven achievements of science have noted significant advantages in this device.
Firstly, the feeling of anxiety at the sight of a flashing mobile charge indicator will disappear. Experiences alone bring many problems, not to mention the consequences of a really dead battery. Secondly, self-confidence and a feeling of some security appear. Who doesn’t agree with security, look at those people who are feverishly running around with exercises. And if they haven't found a power source, what do their thoughts become? They are desperate. The situation may force you to ask passers-by to call, and if you don’t remember the number by heart and it is stored in the phone’s memory...
It would take a very long time to describe the inconvenience caused by a dead battery. Everyone understands that this is very bad. It is worth considering the benefits of having a backup battery, its pros, characteristics and disadvantages.
Characteristics
The functions declared by the manufacturer are insignificant. Since the Xiaomi Mi Power Bank 10400 mAh device is very simple, it does not offer many additional functions. Xiaomi describes the presence of the following parameters:
- Battery capacity is 10,400 mAh, which is 3.5 V;
- Li-ion battery type with input power 5 V and output power 5.1 V;
- there is protection against overheating, the device automatically turns off;
- battery weight 250 grams;
- battery size 21.5 * 77 * 90.4 mm;
- the maximum number of charges is five thousand.
That's all. The list is not long. I am very pleased with the power output when charging. With these options, you can charge your phone in less than an hour. If we take into account extreme conditions in which 20 percent of the mobile charge will be enough, then 15 minutes will be quite enough for this. Just 15 minutes and you are in touch until the end of the day. The Xiaomi Mi Power Bank 10400 itself takes longer to charge. Therefore, it is wise to put it on at night, and not immediately before leaving the house.
Equipment Xiaomi Mi Power Bank 10400
By ordering batteries from Xiaomi, you will receive the battery itself and a cord for charging the necessary devices. The cable is very short. This length makes it easy to use and store. This kit is packaged in a plastic box with a lid secured with tape. This use is not very convenient. Few people will enjoy constantly peeling and reapplying tape. If you remove it, the lid simply won’t close and will constantly stick up. This problem is not so great and can be eliminated with the help of a hair tie or a silicone bracelet. It just needs to be placed over the plastic box once the device is inside.
Storing Xiaomi Mi Power Bank 10400 in this form is convenient. You won’t have to look for where the cable went, since everything will be in one place. Losing cords is a universal problem that affects almost everyone.
Design Xiaomi Mi Power Bank 10400
The appearance of the backup battery is in the shape of a parallelepiped. At the end there are four indicators that show the percentage of charge of the device. Each individual indicator indicates 25% charge, which adds up to 100%. Next to them is the power button. It does not turn off the device. This button is needed to turn off the charging of the device or the transfer of energy from it. Further on the same panel there are two inputs, or two ports. One for standard USB, the second for mini.
The body of Xiaomi Mi Power Bank 10400 is aluminum, the edges are rounded. Externally, the backup battery looks like a box and fits easily and comfortably in your hand. When carrying the device near a mobile phone, friction may be created and scratches may occur on both the battery and the gadget. To preserve the appearance of your devices, you can simply place the Power Bank with your smartphone in different places so that they do not come into contact with each other. Or use special covers. For Xiaomi Mi Power Bank, manufacturers have produced a silicone case that protects the device from scratches. Its price is half the cost of the backup battery itself. If the type of battery is not very important to you, and you don’t want to spend extra money on cases, you can simply put children’s multi-colored silicone bracelets on the case, which are now sold in almost every store.
Conclusion
What can we say about Xiaomi Mi Power Bank, considering all the pros and cons? There are plenty of advantages and even more than that. And the disadvantages, even if there are any, seem so insignificant that no one pays attention to them.
Among the advantages can be noted:
- Low cost of the goods;
- practicality in use;
- in some moments necessity and indispensability;
- long service life of the device;
- no additional costs required.
By purchasing a backup battery, the user will save himself from unnecessary worries associated with a dead phone and will be able to have constant access to the Internet and cellular communications. Your outdoor holiday won't be ruined because of a low-powered camera, and you'll always be able to capture joyful moments. Xiaomi Mi Power Bank is an indispensable companion for a modern person.
How many nerves do we lose when our phone dies? We are constantly afraid that when the battery runs out, a small apocalypse will come for us. And it will last until we find an outlet. But what should people do who don’t have an outlet at hand, but need to stay connected? One of the solutions was proposed by the Chinese company Xiaomi, which, in addition to smartphones, pays great attention to accessories, and at a reasonable price.
We already discussed some time ago the two most popular batteries from the Chinese noname industry in this. As it turned out, they were not of very high quality, and their power in fact turned out to be three to four times less than declared. It's time to move on to something more interesting and of higher quality.
Today we will talk specifically about Xiaomi Mi Power Bank.
The latter is a stand-alone charger for any gadgets, including smartphones, tablets, cameras - whatever. Initially, the company offers 3 portable charging options. The only difference is in capacity: 5200 mAh, 10400 mAh and 16000 mAh.
Let's focus on the intermediate version with a capacity of 10400 mAh.
Equipment
Everything is very democratic here. The charger came dressed in a branded wrapper with Chinese characters on top of a plastic case. No extra box. Tearing open the wrapper, we find a transparent case with a device inside, a wire and brief instructions, again in Chinese. Special thanks to the seller from Ebay, who spared no pimply polyethylene on my parcel, thanks to which it arrived safe and sound. Obviously, the guy has already encountered the peculiarities of Russian customs and the valiant Russian Post.
The case, I must say, is not very convenient. It is held on top and bottom by word of honor and tape. It is not very convenient to constantly peel it off. Alternatively, you can leave it on one side, say, from the bottom, and peel it off from the top. It won’t open on its own, but it won’t hurt to tighten it with a rubber band.
Design
Let's go over the appearance.
So, on the top end there is a single power button, two USB ports (regular and Micro) and 4 indicators. It’s clear why the power button is needed - 4 indicators show the battery level at 25%. While the recipients are charging, the indicators blink, allowing you to understand whether it has enough energy to charge something else. The Micro USB port is used to charge the device itself from any suitable adapter with the appropriate input. The full-size port is used to charge gadgets.
It is worth noting that the kit includes a short Micro USB -> USB cable, which fits comfortably into a small compartment in the storage case. This complete set will upset owners of Apple gadgets, as they will have to buy an adapter from Micro USB to Lightning. Moreover, the original adapter costs more than the charging itself. But online stores (Ebay or Aliexpress) have not been canceled and, if desired, you can buy several “not entirely original” adapters for much less money. Read on for a review of such a modest but important contraption.
Below we can see large numbers with the battery capacity and several hieroglyphs indicating the input and output power. More details about the specifications below.
The sides of the device are rounded. This design move made it possible to cleverly hide 4 cylindrical batteries inside. Thanks to this, the device fits comfortably in your hand, although constantly holding it in your hands while charging gadgets is inconvenient and unnecessary.
In general, this device clearly shows Xiaomi’s penchant for minimalism. A similar design can be seen on most of the company’s accessories and devices.

Experience of use
A battery of this power should last a long time. It was experimentally determined that the full charging capacity is enough for:
| Device | Number of charges, times | Charge level on the device when power is connected, % | Charging time |
| Google Nexus 7 (2013) LTE (Asus) | 3.5 | From 14% to 100% | 1.2 hours |
| Google Nexus 5 (LG) | 6 | From 14% to 100% | 1 hour |
| Apple iPhone 5S | 6.5 | From 20% to 100% | 55 minutes |

| Canon EOS 60D | 6 | From 5% to 100% | 1.1 hour |
Today we received an external battery for charging phones and other gadgets produced by the popular Chinese brand Xiaomi PowerBank 10400 mAh. This model is the middle one in the line of their power banks - there is also a lightweight version for 5200 and 16000. If the younger brother is thinner in appearance, but longer, then the older one is slightly narrower, but much longer and heavier. Therefore, I purchased the 10400 model for personal use as the optimal ratio of price, size and capacity for everyday wear.
Equipment of the original Xiaomi Power Bank 10400 mAh
By the way, about gravity. We are accustomed to the fact that cheap Chinese batteries have a significantly lower capacity than indicated on the label. And the main signal for this is their light weight. For those who don’t remember, I already once ordered an extra battery for a Samsung phone and just fell for this trick.
The same story is possible with PowerBank from Xiaomi - of course, this is a serious brand and the original charger fully corresponds to the quality expected of it. However, there are many fakes on the market that can leave a less pleasant impression. Let's unpack and look at the original device and note those elements by which it can be distinguished from a fake.
In the official delivery we have the following equipment^
- the battery itself
- small flat micro USB cable
- and instructions.
There is no power adapter, so you can use any 5V/2A adapter - the option from the same mobile phone will do.
How to distinguish an original Xiaomi Power Bank from a fake?
First of all, let's look at the packaging - on the side of the branded box there is a sticker with a hologram and a protective layer, under which there is a 16-digit verification code.
Using it on the website http://chaxun.mi.com you can check whether this device is original and how many times a check was requested using this code on the website.
Our copy turned out to be original.
The second accessory worth looking at is the charging cable. In the branded kit it is longer - 22 cm. Also, the fake often has an embossed image of the Xiaomi logo - it is not on the original.
Externally, the powerbank is a solid-body box made of durable gray anodized aluminum. The coating is rough and does not try to slip out of your hands, although the security of the battery is also high - according to the manufacturer, it can withstand weight up to 50 kg.
Overall it creates a very pleasant impression of a high-quality, reliable device. This can be said about all Xiaomi brand devices, which, despite their relatively low cost, have an imprint of “glamor” on them - with all the technical advantages, they are simply pleasant to look at or hold in your hands.
Hidden inside are 4 18650 capacitive batteries manufactured by LG.
At the same time, in the original device, the assembly of all parts is done so well that the side plastic edges do not play and nothing rattles inside. On the main side panel we have all the indicators and controls. This:
- power button
- 4 LEDs - battery full indicators
- micro USB connector - for replenishing energy reserves on the most portable charger
- and regular USB for charging devices.
Here you can notice another difference with the fake - on the latter, all the elements are made less carefully.
The power button is only needed to check the remaining capacity of the power bank - it is signaled by LEDs. When you connect your phone to charge, the device turns on automatically.
Another way to check for lice is to connect the battery to itself - from micro USB to large USB. The fake will begin to charge itself, but the original will not.
And finally, let's look at the opposite side, where technical information about the PowerBank is printed - on the fake one the print is brighter.
How long does the charge last?
We could check how many times this portable charger can be used on two devices - Apple iPhone 5S and iPad Mini. On an iPhone with less than 20% discharge, it lasted 6 times, with the average time ranging from 50 minutes to an hour. The iPad can be charged 2 times - both in just over an hour.
It is also worth noting an interesting thing here - despite the fact that the battery capacity is stated in large print as 10400 mAh, this value refers to the case if the output voltage was 3.6 Volts. But the standard voltage on the USB connector is 5 Volts, resulting in
the actual volume is almost halved to 6650 mAh.
Moreover, all this is absolutely honest, but unobtrusively indicated by the manufacturer in small print on the sticker. Can you imagine how small the volume of a 5200mAh charger really is?..?
As an additional accessory for the Xiaomi external battery, you can purchase a silicone case, which is produced in several colors. It will not only give a bright appearance, but also protect the phone and other objects from scratches that can be caused by the sharp edges of the PowerBank.
That's all - buy, the main thing is to carefully inspect the battery before purchasing and read reviews about the seller. Good luck!
