External battery Xiaomi Mi Power Bank 2 10000mAh silver color is a logical continuation of wearable batteries from famous 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 remained at 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 October, Xiaomi released its new external battery Xiaomi Mi Power Bank 2 (PLM02ZM), which replaced the legendary Xiaomi Mi Power Bank 10000 mAh (NDY-02-AN). Externally and in terms of characteristics, it is very similar to the Mi Power Bank Pro, but significantly cheaper. In the review, I will tell you in detail about the new external battery and compare the real characteristics with the Pro version.
If you want, you can pre-read my two previous reviews of Xiaomi Mi Power Bank Pro and ZMI QB810, tk. they are directly related to Xiaomi Mi Power Bank 2. But this is not at all necessary, but just for information.
Yes, the review is made according to the rules of clause 18, i.e. provided by the store for review. So I am pleased to read some of the scathing comments from some on the topic of "venality of authors", "earned millions on resale" and other amazing stories. Chick-chick-chick ...
Make yourself some tea or coffee and let's get started!
Equipment
The external battery is supplied in a standard package for Xiaomi.
The packaging contains specifications, secret code under the erasable protective layer to verify the authenticity of the product. You can check by. My package was slightly crumpled upon delivery, but everything inside is intact.
Inside: external battery, USB cable A<>micro-USB, Chinese Quick Start Guide. Micro-USB cable approx. 30 cm long.
Appearance
There are two colors of the external battery: light (silver) and dark (black). I have a light version in my review.The design of the device is very similar to the Xiaomi Mi Power Bank Pro, it is even easy to confuse them. From left to right: Xiaomi Mi Power Bank Pro, Xiaomi Mi Power Bank 2, ZMI QB810.
Measured size 130 x 71 x 14.3mm. Weight 226 g. For comparison, the dimensions and weight of the Pro version are: 128.8 x 75 x 12.9 mm, 217 g.
The main body is made of anodized aluminum. Plastic overlays on the ends. The technical characteristics are traditionally indicated on the bottom end.
The Mi logo is embossed, which has not been found in other Xiaomi external batteries.
At the top there is: a function button, a battery indicator, a micro-USB port, a USB A port.
Function button assignment. With a short press:
- Display of the charge level by indicators.
- Forced activation of the device, supply voltage (if the device is in standby mode).
- Restarting the external battery controller (if the device is working).
- Resetting some protection modes (for example, the device went into overcurrent protection).
- Enable / Disable Xiaomi gadgets such as flashlight or fan.
- Enabling the charging mode for devices with low current consumption (the battery does not go into standby mode for exactly 2 hours).
Testing tools
For testing, I will use my standard set:- Tronsmart QC 2.0 Charger
- ZKE EBD-USB tester and load (supports QC 2.0 / 3.0) with computer control
- JUWEI J7-t USB High Voltage Tester and QC Mode Switch
- iPad mini (to test smart charging)
- Pyrometer and other little things
Protection
Declared protection functions: input overvoltage, input polarity reversal, output overcurrent, output overvoltage, output short circuit, battery overcharge and overdischarge, battery overtemperature. With the safety of Xiaomi external batteries, everything is always at the highest level.
When the protection is triggered, Mi Power Bank 2 turns off. It returns to working condition by one of the three ways(the method depends on the type of protection triggered). The first is that the battery will return to working condition on its own. For example, if the overtemperature protection is triggered. Second - press the button on the external battery. For example, if you exceed the permissible current. Third - connect the external battery to the charger. For example, if there is a short circuit at the output.
I have tested three types of protection. Overload protection - the device has shut down (you can read more in the "Load" section). Output short circuit - the device has shut down. Exceeding the input voltage - applied 20 V to the input, the device turned off.
Charging the external battery
Xiaomi Mi Power Bank 2 supports Qualcomm Quick Charge 2.0 input technology and can be charged at 5V, 9V and 12V.Everything external batteries Xiaomi supports pass-through charging. You can simultaneously charge devices from an external battery and the external battery itself. Xiaomi Mi Power Bank 2 also supports pass-through charging, but here it is easier to implement than in Mi Power Bank Pro. It all depends on the device being charged. I'll tell you with an example. Mi Power Bank 2 is connected to a charger with QC 2.0 support. If you connect a device without QC 2.0 support to it, then the input voltage switches to 5 V: 5 V> 5 V. If you connect a device with QC 2.0 support, the input voltage will correspond to the voltage requested by the device being charged: 9 V> 9 V, 12 V> 12 V. e. switching without a converter. Mi Power Bank Pro uses a converter when charging through. For example, the input is 12 V, and the output may be 5 V.
The charge graph looks like in the following way(red - current strength, blue - voltage): 
The first second Mi Power Bank 2 "communicates" with the charger, the charger switches to 9 V. Then the external battery starts to consume 18 W with a further increase to 18.5 W. So it goes on 2 hours 8 minutes, during this time the external battery is charged somewhere before 83% ... Then the charge controller goes into CV mode, the current gradually decreases, and the full charge (the remaining 17%) is achieved in another 1 hour and 20 minutes. Full charge time 3 hours 28 minutes... Mi Power Bank Pro takes about the same time to charge - 3 hours 24 minutes.
During charging, the highest temperature recorded near the micro-USB port is 39 ºC: 
If you read my review of the ZMI QB810, which is the twin brother of Xiaomi Mi Power Bank 2, then you know about one feature - this external battery does not really like to charge at 5 V (it loves QC modes), limiting the maximum current to 1.5 A In Xiaomi Mi Power Bank 2, the charge controller is programmed differently, and the external battery happily draws a current of 2 A at 5 V.
The full charge time with 5 V is 5 hours 28 minutes.
In 5 V no-load mode, the voltage is 5.23 V. As the load increases, the voltage gradually drops. Peak current 2.6 A at 4.99 V. Output power 13 W. With a further increase in the load, protection is triggered.
In 9 V mode without load, the voltage is 8.93 V. With increasing load, the voltage gradually drops to 8.77 V at a current of 2.1 A. With an increase in current to 2.2 A, the voltage drops sharply to 6.1 V. With a further increase in the load, protection is triggered. Output power 18.4 watts.
In the 12 V no-load mode, the voltage is 11.88 V. With an increase in the load, the voltage gradually drops to 11.76 V, the current strength is 1.7 A, the power is 20 W. With a further increase in the load, protection is triggered.
The Xiaomi Mi Power Bank 2 copes with the load perfectly, demonstrating characteristics that are higher than those stated. For comparison, output power Mi Power Bank Pro at 5V, 9V and 12V: 12W, 21W, 23W.
Smart charging
Apple's charger emulation mode works with D + 2.7 V, D- 2.0 V. the maximum current for Apple devices is 2 A. IPad connection mini did not cause any problems, it consumed 2 A. No complaints.
Measurement of stored energy (capacity)
The nominal capacity of the internal battery, according to the manufacturer, is 10,000 mAh at 3.85 V or more understandable 38.5 Wh. Of course, considering the conversion losses, the stored energy will be lower.The measurements will be carried out in three modes: 5 V / 1 A, 5 V / 2 A, 9 V / 1.6 A or 12 V / 1.2 A. To assess, two of the most common modes at 5 V and one limit according to specifications are sufficient. QC 2.0. To maximize losses, I will use 12V in the latter mode.
Discharge with a current of 1 A with a voltage of 5 V
Xiaomi Mi Power Bank 2 was discharged in 7 hours 1 minutes. The maximum case temperature of the external battery was less than 28 ° C. With an average voltage of 5.14 V, the stored energy was 36.03 Wh - 94%
from the declared internal battery. An excellent result for a modern external battery. It falls a little short of the Mi Power Bank Pro, which has 37.99 Wh in a similar situation.
Discharge with a current of 2 A with a voltage of 5 V
Xiaomi Mi Power Bank 2 was discharged in 3 hours 22 minutes. The maximum case temperature of the external battery was 32 ° C. With an average voltage of 5.03 V, the stored energy was 33.82 Wh - 88%
from the declared internal battery. The lag behind the Mi Power Bank Pro is increasing, which in a similar situation has 37.47 Wh.
Discharge with a current of 1.2 A with a voltage of 12 V
Xiaomi Mi Power Bank 2 was discharged in 2 hours 26 minutes. The maximum case temperature of the external battery was 38 ° C. With an average voltage of 11.35 V, the stored energy was 33.21 Wh - 86%
from the declared internal battery. The Mi Power Bank Pro has 35.18 Wh with a higher current (1.5 A).
Pay attention to the discharge graph. Xiaomi Mi Power Bank 2, like the ZMI QB810, could not hold the voltage throughout the entire discharge process; at the end of the discharge, the output power dropped to 10 W. The Pro is easily capable of delivering 18 watts throughout the entire discharge phase without restriction.
Mi Power Bank 2 demonstrates excellent capacities, but lags slightly behind Mi Power Bank Pro.
Parsing the device
The device is disassembled in the same way as the Xiaomi Mi Power Bank Pro. Peel off two plastic pads from the ends, unscrew the two screws from the bottom and take out the insides.The popular Chinese site Chongdiantou already has this power bank right on the first day of sales. I will use their pictures of the insides.
A dual Lishen battery is installed inside. The Xiaomi Mi Power Bank Pro also uses Lishen, but a different model. The maximum battery voltage is 4.4 V. A thermal sensor is connected to the batteries.
The charge controller and boost converter are here in one microcircuit - ZMI P02Q6RB. The same microcircuit is responsible for "smart" charging (coding) at the output. The ZMF 1206USBN controller controls everything (most likely, it is ABOV 1206USBN, similar controllers are used in other external Xiaomi batteries).
For comparison, the Xiaomi Mi Power Bank Pro uses the popular combination of Texas Instruments BQ25895 (charge controller) and Texas Instruments TPS61088 (boost converter) instead of ZMI P02Q6RB.
Conclusion
Xiaomi Mi Power Bank 2, given its cost, will certainly succeed, like its legendary predecessor Xiaomi Mi Power Bank 10000 mAh. This is a perfectly balanced external battery with a capacity of 10000 mAh. The Mi Power Bank Pro is just a little short of the stored energy and maximum output power, but at the same time it has a significantly lower price.I will list the strong and weak sides Xiaomi Mi Power Bank 2:
- Quality of materials and workmanship
- Good indicators of stored energy
- Supports QC 2.0 output and input
- Price (when compared to competitors)
- Dependence of the output power in QC 2.0 modes on the battery charge
And, to make it easier to navigate, I will write the main differences from Xiaomi Mi Power Bank Pro:
- Slightly less stored energy
- Slightly less maximum power output
- There is a dependence of the output power in QC 2.0 modes on the battery charge
- Micro-USB port instead USB Type-C
The product is provided for writing a review by the store. The review is published in accordance with clause 18 of the Site Rules.
I plan to buy +30 Add to favourites I liked the review +37 +78In 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 different schemes... To restore the activity of 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 maintain 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;
- You need to charge Paver 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 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:
- Before the whole the lineup Xiaomi's external battery 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 slipping plastic. 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 port... 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 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 or other problems. 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.
All in all, Xiaomi review Mi Power Bank has shown 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 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 is the most powerful smartphone it can charge multiple 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;
- 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 the purchase of the original Paver Bank is;
- Full Apple charging 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 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 find an external battery with such a high capacity for affordable price from another manufacturer is simply impossible.
If you do not trust the manufacturer or you 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 from this - the battery from Xiaomi is of high quality.
