As a general rule, when buying a portable battery for a mobile device, experts advise avoiding cheap models, especially those whose specifications seem too good to match the price at which they are sold. But from time to time, products appear that refute this rule. An example of this is the 10400 Power Bank.
Inexpensive and powerful
Like smartphones from Xiaomi (and not only), the price of the device is much cheaper than similar offers from competitors. By comparison, a 10,000mAh branded battery typically costs around $ 100. How much will the Xiaomi Power Bank for 10400 mAh cost? For only $ 13.99.
Of course, there are other energy banks available and powerful. Taobao regulars will confirm that inexpensive powerbanks are abundant in the Chinese internet market (eg Romoss), but shipping and warranty issues can be problematic.
So, is the Xiaomi Mi 10400 Power Bank worth the money spent on it?
Design overview
About the design of the energy bank, besides the fact that the $ 14 product looks and is assembled very well, the following can be said. The main body is CNC-cut from a single piece of aluminum and anodized to give the surface a slightly textured surface for added grip. Xiaomi claims that the coating does not break with water, does not corrode and can withstand a load of 50 kg (although users advise against checking this). The surface has also passed a 300-fold abrasion test. The metal housing allows you to quickly dispose of excess heat, which extends the battery life.
The only plastic parts of the Xiaomi Mi 10400 Power Bank are the top and bottom ends of the device. On one end, there is a standard USB output port, a Micro-USB input connector, 4 LEDs and a round capacitance test button. The other end has specifications and regulatory symbols printed on it. Xiaomi representatives are confident that the buttons and ports are self-explanatory, so they didn't even bother to label them.
There is no need for a power switch as the battery is automatically activated and charges the device when it is connected with a USB cable. The purpose of the capacity test button is to turn on LED indicators that will inform you how much charge is left. In short, each indicator corresponds to 25% of the charge. When the battery is fully charged, all LEDs are on and not blinking. The brightness of the indicators is sufficient - not too bright to dazzle at night, and not very dark to be invisible in bright light.
Contents of delivery
Xiaomi Mi Power Bank 10400 Silver is sold together with 16 cm white Micro-USB flat cable and user manual. Given that a rechargeable device shouldn't be too far away, this is one of the few times that such a short length makes sense. Users love the flat cable because it is shaped to prevent easy tangling. not attached.
Reliability and durability
Some more technical data. According to Xiaomi, the Micro-USB port of the device is capable of withstanding 5000 cycles of use, and the larger USB connector is designed for 1500. Xiaomi has even presented the results of ESD testing: 8 kV on contact and 12 kV for air. Obviously, the manufacturer is trying to do everything possible to reassure potential buyers that the Xiaomi Mi 10400 Power Bank is a quality product despite its low cost. In fact, the above data is not all. The device has been tested in low and high temperatures, high humidity, temperature fluctuations and in a salt chamber.
The company claims that the portable battery comes with 9 levels of protection. These include a mechanism to control heating temperature, input and output voltage and current, prevent short circuit, overcharge or over discharge, and reboot in unstable environments.
Performance
The model comes with a lithium-ion battery, manufactured by LG or Samsung, with a capacity of 10.4 Ah, which corresponds to 37.44 Wh at 3.6 V. As the experts explain, due to the loss of power during voltage conversion and circuit resistance, the number of recharges that the energy bank provides is not determined by simply dividing 10,400 mAh by the battery capacity of the device being charged. According to Xiaomi, Mi Power Bank 10400 mAh allows you to charge an iPhone 5s 4.5 times, a Mi 3 2.5 times, and an iPad Mini one and a half times. According to user reviews, these numbers seem to be quite accurate, as they managed to recharge the iPhone 5s, which has a battery capacity of 1560 mAh, four times, and they still have a little charge left.
Thus, the efficiency of the device is about 93%, which gives a net 7000 mAh. This is much more than most food banks on the market offer.
Charging speed
In addition, the owners are very happy with the input and output current of the power bank. To be precise, the device is capable of outputting up to 2.1 A, which is great for tablets and smartphones that can take more than the standard 1 A. Even the charging input port is rated for currents up to 2 A. This is unexpected for such a cheap power bank. because there are many expensive batteries on the market that cannot handle more than one and a half amperes. In other words, Xiaomi Mi Power Bank 10400 mAh charges pretty quickly. According to the manufacturer, this takes about 5.5 hours with a 2 amp adapter or about 10 hours with a 1 amp adapter.
The device is capable of charging and recharging at the same time. Only a few power banks offer this option, and it is necessary when the number of available outlets is limited - for example, when traveling.
What is inside?
Users who could not come to terms with the fact that a high-quality external battery can cost so little, were able to verify this by looking at what is inside it. The device consists of four batteries manufactured by LG, each of which has a capacity of 2600 mAh for a total of 10400 mAh. According to the manufacturer, the power bank uses Texas Instruments controllers. Indeed, the external battery is powered by the TI BQ24195 chip. The circuit also uses an 8-bit South Korean microcontroller ABOV.
Advantages and disadvantages
So can we recommend the Xiaomi Mi Power Bank 10400 external battery? Of course, yes. And not only because it is cheap - the energy bank is inexpensive and does its job well. For a 10.4 Ah battery, it is compact, delivers 2.1 A of output current, is capable of fast charging with two amps, and the components used look convincing.
Does the device have disadvantages? If you find fault with the little things, then we can say that for an external battery of such a high capacity it is strange to have only one output. This means that it is impossible to charge more than one device at the same time. Again, you can always buy another portable power bank and connect it with a rubber band - you get two ports and a 20800 mAh bank for only $ 28! Secondly, the kit does not include a power adapter, which can be a problem if there is no extra in stock. Finally, iOS users will have to find their own Lightning cable.
Finally, if for some reason 10400 mAh seems too much, then you can purchase an external battery of the same manufacturer with a capacity of 5200 mAh. It is smaller and appears to be made up of similar components, except that the number of batteries is reduced to two, and the output can only be 1.5 A.
The external battery Xiaomi Mi Power Bank 2 10000mAh silver is a logical continuation of wearable batteries from a well-known brand. The company has worked on the design, reducing the weight of the device. And upon closer inspection, you can see that the body has become thinner. At the same time, energy efficiency has remained at a high level. So you can buy a device to keep your smartphones and gadgets in working order in any conditions.
The hull is another reason to be proud. It is made of metal and is not afraid of moderate physical influences, falls from a small height, etc.
What is inside
Despite the name of the model, which indicates the total volume of the battery, the free amount of energy given to gadgets is 3 thousand mA / h less, which should be remembered when purchasing. The rest of the indicators are interesting:
- support for fast charging function;
- battery charge status indication;
- quick recovery of the energy reserve when fully discharged.
Light weight and compactness allow you to carry the gadget with you even every day without any discomfort. The price of a Chinese product is traditionally in the affordable segment.

In the modern world, there is nowhere without energy. Your computer, laptop, tablet, smartphone are powered by a power supply. When the charge runs out, the devices cease to perform their duties and turn into a useless heap of plastic, metal and various circuits. To restore activity to the device, it must be charged. But what if there is no such possibility? Xiaomi offers an alternative - Power Bank. This device allows you to compensate for the loss of charge without using an external power source. Simply put, it is an external battery that is able to keep a smartphone or tablet in working order for a fairly long period of time.
The original Xiaomi Mi 20000 mah is the most powerful external battery in the package of this manufacturer. In addition, the buyer is attracted by the affordable price of this Energy Bank. For example, if you need to buy approximately the same device from another manufacturer, then it will cost several times more, while the Chinese company offers a high-quality and affordable gadget. Let's see what is the peculiarity of the battery.
Characteristics of Mi Bank 20000 mah
This device is the most powerful among all external batteries that Xiaomi has released. What is so special about this device? This can be understood if you just look at the characteristics of the device:
- The battery has the following input voltage: 5V / 2A, 9V / 2A, 12V / 1.5A;
- The v2 device has a dual external output. Any of these USB ports work with 5.1V / 2.1A output;
- The battery capacity of this model is, depending on the assembly: 19020/20000 mAh (3.6V);
- If you believe the data declared by the company, then the minimum effective capacity of this external battery is 12,700 mAh;
- Qualcomm QuickCharge 2.0 is supported for charging the device;
- Operating temperature range from -20 degrees to +60. That is why neither hypothermia nor overheating of the battery can be allowed, otherwise it will stop working;

- The dimensions of the Power Bank are 142 x 73 x 21.8 mm, and the weight is 338 grams, which is surprising with such a capacity.
This is the most powerful external battery of the manufacturer in question. The weight of the device could have been much larger, but the company went to some tricks to keep the device compact and not harm its performance required for operation.
Design Features Xiaomi Power Bank 20000
As soon as you see a gadget, a new design solution immediately catches your eye, thanks to which, even outwardly, this Power Bank began to differ from its counterparts. Let's see what the design features of the gadget in question are, and how good or bad it is for the buyer:
- Previously, the entire range of Xiaomi external batteries was made of aluminum. It looked expensive and stylish, in addition, it protected the inside of the device from external damage. But this time, the company decided to replace the metal with plastic. What happened? In fact, nothing - this is such a strategic move that allows you to reduce the weight and price of the device. Simply put, a person will now have to pay only for the performance of the battery, and not for what material it is made of;
- The device has become more practical, since plastic, especially one as high-quality as this one, is more difficult to damage and scratch. But in fairness, it should be said that the device still lost part of the premium. Although why should she, if the main purpose of chargers is to recharge other devices, in particular smartphones and tablets;
- There are small bumps on the top and bottom panels of the case, which allow you to remove the effect of plastic slipping. In principle, such a solution looks pleasant to the eye, therefore it has not only a practical, but also a decorative function. Although the design is not for everybody;
- There is a control button. She is the only one, therefore it is almost impossible to confuse her with something else. This key is located on the side panel of the Xiaomi Mi Power Bank 20000mah, which we are currently reviewing;
- There are also four LEDs on the Xiaomi 20000mah panel. They are something like an indicator showing the battery level. In general, the same specifics of the work of any Mi Power Bank battery.
The gadget is bundled with a USB cable, the length of which is 30 cm. But the bundle does not include a power supply, so when you need to charge the unit, you can use the charger from your phone or the same tablet. All in all, a pretty profitable solution.
How the Xiaomi 20000 Power Bank is equipped
When we figured out the design, we must definitely see what kind of filling is under the high-quality plastic. And it must be no less cool, otherwise the manufacturer would not have been able to create a battery with such a capacity. And the good news is that you don't need to remove the battery cover. We will do it for you. So, inside is the following:
- The design of the Mi Power Bank 20000 mah, which we are reviewing, includes a set of Li-ion-rechargeable batteries from LG and in size 18650. There are six such cells in the battery. Each of them has a capacity of 3350 mAh. so that the total "weight" of the structure is not difficult to calculate;
- The design has two USB ports. Each of them produces a current of 2.1 A. But if both ports are working, then the total current issued by them during operation should not exceed 3.6 A;
- There is an intelligent mode that makes it much easier to work with gadgets that operate with different currents. Unfortunately, charging a device like the Apple 2.4A is nearly impossible. This is a disadvantage of this block. But if you don't have such a phone, you don't have to worry, because not everyone has the opportunity to buy iPhones;
- The voltage in the USB ports of Xiaomi 20000mah Mi Power Bank adjusts to different types of loads. The voltage level may exceed the declared standard of 5 V. This is a common solution for devices of this type. Simply put, when connected, neither the connected device nor what is being charged will suffer;
- There is overvoltage protection both at the input and at the output. Therefore, the work of the UMB Xiaomi Mi Power Bank 20000 mah is completely safe. There will be no short circuit, no overvoltage, no other problem. And if they do, then both the unit itself and the device that is connected to it will be reliably protected;
- Provides technology Quick Charge 2.0., Popularly known as high-speed charging. It allows you to significantly speed up charging, which is beneficial if you are short on time and the gadget needs to be charged as soon as possible. But high-speed charging allows you to charge only the Power Bank, and not the devices that are connected to it, which limits the functionality;
- In addition, Mi Power Bank 20000mAh supports transit charging method. This means that when the Power Bank is charged from the mains, it does not lose the ability to charge other devices.
In general, the review of Xiaomi Mi Power Bank showed that the battery is very good, despite minor flaws. Perhaps the device will soon get even better when the next version is released. It will be more powerful and better developed. But even now we have nothing to complain about.
Features of the application of the Power Bank 20000mAh
Why do you need a battery with such a large capacity? In order to charge not only smartphones but also tablets. True, in order to charge the tablet, the charge in the battery will not last long, but at least one procedure will be enough. But the Chinese most powerful smartphone, it can charge several times. In other words, you may not go to the outlet for at least a week, or even longer. Isn't that great news?
If you have a laptop that can charge via a USB port, then the gadget can easily charge even it. Once you have enough of it to extend the life of the laptop, well, then you have to look for an outlet, and again charge the device. In general, the battery can handle even the most powerful batteries.
- In order to restore the work of a new MacBook, the charge is only enough for one time, a maximum of two;
- To charge the Apple iPhone 6, the device is enough for as many as seven times. Calculate how long this smartphone works without recharging, and you will know how profitable the purchase of the original Paver Bank is;
- Fully charging Apple iPad mini using the device in question is only possible four times. But it is worth noting the significantly increased performance of this gadget, compared to a smartphone. Naturally, a powerful battery is installed on it, which "burns" more of the charge coming from the external battery.
As you can see, the device is more than necessary in everyday life. It is especially needed when you are on the road, travel by train for several hours or go to nature for a long time. In general, you are where there is no access to power outlets and there is no way to charge your smartphone when you need it.
Plus, transporting a fully charged device is convenient. The fact is that the gadget is small both in size and weight. It is so compact that it can easily fit in a large pocket, not to mention a woman's purse. In general, it turned out that the battery is not only very high quality, but also affordable. And it is simply impossible to find an external battery with such a high capacity at an affordable price from another manufacturer.
If you don’t trust the manufacturer or are dealing with it for the first time, you can watch a video review of this device. There are a lot of them on the Internet. But you can at least watch all the videos with reviews, the result will not change - the battery from Xiaomi is of high quality.
