A power bank is a device that can take care not only of itself, but also of the safety of the equipment connected to it.

History of portable batteries Xiaomi started with the Mi Power Bank 10000 mAh, which is still the world's most popular portable battery for charging electronics. Over the past two years, the Chinese corporation has managed to release a large number of other portable batteries, but it is the version with 10,000 mAh capacity that is the most optimal, according to many.

At the beginning of 2017, Xiaomi presented and began selling the Mi Power Bank 2 10,000 mAh battery, which differs from its predecessor in a thinner body, new hardware and, of course, a higher maximum current strength - 2.4A versus 2.1A in the first generation.

You can buy Xiaomi Mi Power Bank 2 10000 mAh in two colors – Silver and Black. In our case, the choice fell on black, as it looks more “fresh” and interesting. Otherwise, except for the difference in color, the two versions of the second generation portable battery are no different from each other.

The Mi Power Bank 2 10000 mAh comes in a stylish white package with an image of the device itself on the front. Since most Xiaomi products are intended for sale in China, the box has inscriptions on all sides: Chinese. I would like to believe that in the near future the company will finally begin to carry out all the designations on English language, which will allow it to more actively promote its products on the international market.

In the package you can find another one, inside which there is a small manual in Chinese, a microUSB - USB cable, as well as a black portable battery itself.

The length of the microUSB cable is 30 cm, whereas in the first generation it was 20 cm. Most likely, Xiaomi employees realized that buyers of portable batteries experience inconvenience due to too short charging cables, so the Xiaomi Mi Power Bank Pro with a connector USB Type-C The cable length has increased to 30 cm.

Of course, the greatest interest is the Mi Power Bank 2 10000 mAh itself. The black color in real life beautifully and gracefully shimmers into purple and dark blue colors. In general, the black color turned out to be very unusual, but extremely on-brand. In just a few minutes, a large number of greasy hand stains appeared on the body. In bright light they are clearly visible.

The build quality of the second generation portable battery is very high level. There are no cracks or distortions anywhere, and the aluminum body has a fairly large margin of safety, so it will not be so easy to damage it. However, the black color of the Mi Power Bank 2 will show scratches and abrasions over time. The solution to the problem may be to purchase a silver model or a protective case.

The dimensions of the Mi Power Bank 2 10000 mAh case are 71 x 130 x 14 mm and weighs 217 grams. For comparison, a model with a similar capacity has dimensions of 75 x 128 x 13 mm and a weight of 218 grams.

The Xiaomi Mi Power Bank 2 10000 mAh portable battery has protection against short circuit, overheat protection, and overload protection. Like all other Xiaomi batteries, there is an LED indicator on the side of the device that tells you the remaining battery charge. Next to it is a glossy plastic button that allows you to switch and independently adjust the current in cases where it is necessary.

The Mi Power Bank 2 10000 mAh battery supports fast charging technology with a power of 9A at a current of 2A. Thanks to this, when using the appropriate power adapter, the time to fully charge the portable battery is 3 hours 30 minutes - we tested.

As for the efficiency factor (efficiency), Xiaomi claims 95% - this is very good result. Thus, the real capacity of Mi Power Bank 2 10000 mAh is 6900 mAh, which is enough for 2.4 charges of Xiaomi Mi5, 3.2 iPhone chargers 6s and 1.4 charges iPad tablet mini 4. All these numbers sound promising, but the editors website I decided to check the manufacturer’s words in practice.

A fully charged Xiaomi Mi Power Bank 2 10000 mAh managed to charge an iPhone SE (1624 mAh) as much as 2 times, and the third time only by 38%. If we talk about charging (5124 mAh), the portable battery was able to charge it completely once, and only 31% the second time. In other words, all the specifications declared by the manufacturer correspond to reality. After a couple of charge-discharge cycles, the capacity of Mi Power Bank 2 may “sway” slightly, so the results will be 5-10% better.

If we closely compare Xiaomi Mi Power Bank 2 10000 mAh and Mi Power Bank Pro 10000 mAh, then both of these portable batteries are only slightly different from each other. The first is equipped with a microUSB connector for charging, and the second uses USB Type-C. The dimensions of the cases are approximately at the same level, as well as the weight. These two batteries fully support fast charging technology Quick Charge 2.0, which allows you to charge them in just 3.5 hours.

Xiaomi claims that the Mi Power Bank 2 can deliver a maximum current of 2.4A, while the Mi Power Bank Pro can only deliver 2.1A. Thus, if you add up all the pros and cons, the new portable battery is superior to its more expensive predecessor in all respects. If we were choosing between these two batteries, then the choice would definitely fall towards the Mi Power Bank 2 10000 mAh model, because, in addition to everything else, it is also almost half the price. We recommend for purchase!

Buy Xiaomi Mi Power Bank 2 10000 mAh at a very low price it is possible.

IN modern world Without energy you can't go anywhere. Your computer, laptop, tablet, smartphone are powered by a power supply. When the charge runs out, the devices stop performing their duties and turn into a useless pile of plastic, metal and various circuits. To restore the activity of the device, it must be charged. But what to do if this is not possible? The Xiaomi company offers an alternative - Power Bank. This device allows you to compensate for loss of charge without using an external power source. Simply put, this is an external battery that can keep a smartphone or tablet in working condition for quite a long period of time.

The original Xiaomi Mi 20000 mah is the most powerful external battery available from 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, it will cost several times more, while the Chinese company offers a high-quality and affordable gadget. Let's see what is special about the battery.

Characteristics of Mi Bank 20000 mAh

This device is the most powerful among all the external batteries that Xiaomi has released. What's 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;
Device v2 has dual external output. Any of these USB ports output 5.1V/2.1A;
The battery capacity of this model is, depending on the assembly: 19020/20000 mAh (3.6V);
If you believe the data stated by the company, the minimum effective capacity of this external battery is 12700 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 should be allowed, otherwise it will stop working;
You need to charge the Power Bank for six hours in order to fully charge it. Provided that a 9V/2A charger will be used;
The dimensions of the Power Bank are 142 x 73 x 21.8 mm, and the weight is 338 grams, which is surprising for such a capacity.

This is the most powerful external battery from the manufacturer in question. The weight of the device could have been much greater, but the company used several tricks to keep the device compact without compromising its performance characteristics.

Design features of Xiaomi Power Bank 20000

As soon as you see the gadget, a new design solution immediately catches your eye, thanks to which even in appearance this Power Bank began to differ from its counterparts. Let's figure out what the design features of the gadget in question are, and how good or bad it is for the buyer:

Previously all the lineup Xiaomi external batteries were made of aluminum. It looked expensive and stylish, and in addition, it protected the inside of the device from external damage. But this time the company decided to replace metal with plastic. What happened? In fact, nothing - this is such a strategic move to reduce the weight and price of the device. Simply put, a person will now only have to pay for the performance of the battery, and not for what material it is made of;
The device has become more practical, since plastic, especially high-quality plastic like this one, is more difficult to damage and scratch. But in fairness, it’s worth saying that the device still lost some of its premium quality. Although why have it if the main purpose of the chargers is to recharge other devices, in particular smartphones and tablets;
There are small pimples visible on the top and bottom panels of the case, which help eliminate the sliding effect of the plastic. In principle, this solution looks pleasing 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, so 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 20000 mah panel. They are something like an indicator showing the battery charge level. In general, the same specificity of operation of any Mi Power Bank battery.

The gadget comes with a USB cable, the length of which is 30 cm. But the package does not include a power supply, so when you need to charge the unit, you can use the charger from your phone or tablet. In general, quite a profitable solution.

How the Xiaomi Power Bank 20000 is equipped

Once we have figured out the design, we must definitely look at 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 with a size of 18650. The battery contains six such cells. Each of them has a capacity of 3350 mAh. so it’s not difficult to calculate the total “weight” of the structure;
The design has two USB port. Each of them produces a current of 2.1 A. But if both ports are working, then the total current they produce 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 2.4 A is almost impossible. This is the downside of this block. But if you don’t have such a phone, don’t worry, because not everyone has the opportunity to buy iPhones;
The voltage in the USB ports of Xiaomi 20000mah Mi Power Bank adapts to different types of loads. The voltage level can exceed the declared 5 V standard. This is a common solution for devices of this type. Simply put, when connected, neither the connected device nor the one being charged will be harmed;
There is overvoltage protection at both input and output. Therefore, the operation of the Xiaomi Mi Power Bank 20000 mah UMB is completely safe. There will be no short circuit, no overvoltage, or other problems. And if they do, then both the unit itself and the device that is connected to it will be reliably protected;
There is Quick Charge 2.0 technology, popularly known as high-speed charging. It allows you to significantly speed up charging, which is beneficial if you have little time and need to charge your gadget 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 network, it does not lose the ability to charge other devices.

All in all, Xiaomi review Mi Power Bank showed that the battery is very good, despite minor shortcomings. Perhaps the device will soon become even better when the next version is released. It will be more powerful and better designed. But even now we have nothing to complain about.

Features of using 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 battery charge will not last long, but it will be enough for at least one procedure. But the Chinese one is the most powerful smartphone it can charge several times. In other words, you don’t have to go near the outlet for at least a week, or even longer. Isn't this great news?

If you have a laptop that can charge via a USB port, then the gadget can easily charge even that. For one time it will be enough for you to extend the life of the laptop, but then you will have to look for an outlet and charge the device again. In general, the battery copes with the charge of even the most powerful batteries.

In order to restore the operation of a new MacBook, the charge will only be enough for one time, maximum two;
For charging Apple iPhone 6 devices are enough for as many as seven times. Calculate how long this smartphone works without recharging, and you will know how profitable it is to buy the original Power Bank;
Fully charged 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, it is installed powerful battery, which “burns” more charge coming from the external battery.

As you can see, the device is more than necessary in everyday life. This is especially necessary when you are on the road, traveling on trains for several hours, or going into nature for a long time. In general, you are in a place where there is no access to sockets and there is no way to charge your smartphone when needed.

In addition, 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 handbag. In general, it turned out that the battery is not only of 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 encountering 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 Xiaomi battery is of high quality.
