Package
The device is delivered in a box with a recognizable design with printing in pale gray tones. On the front there is a photo of the gadget, there is a Mi logo.
Also, according to tradition, on the back are the technical charging parameters:
Options
Charging ports - 6, 5 of which have physical USB interface- A, and one more - USB - C.
4 ports - have a standard voltage of 5 V, maximum total current up to 4.8 A, no more than 2.4 A per port.
Another USB - A and USB - C port support QuickCharge 3.0 technology, the maximum current at a voltage of 5V is 3A, 9V - 2A and 12V - 1.5 A.
Device dimensions - 110*80*20 mm, operating temperatures from 0 to 40 C
What is in the box
Inside the outer box is another, inner box, divided into two parts.
One contains charging station, in the other - the power cable.
Actually, nothing more interesting is included in the kit, and nothing more is needed.
The included cable has a flat American-style plug; on the charging station side there is a standard two-pin connector, which is often found in various equipment.
Appearance, design
The panel with the connectors is sealed with a shipping sticker, a bit of a funerary appearance.
Down with the sticker, under it are the promised 6 USB port ov. First USB C, then USB A with QC 3.0 support, and then 4 regular 5 Volt
The body is white and glossy, but not particularly easily soiled. The top panel shows the MI logo - but in a very light gray color.
On the lower part of the body there are 4 small legs in the corners.
At the back, in the center, there is a two-pin connector for the power cable. By the way, it is not necessary to look for an adapter for the supplied cable.
I found a free suitable cable with a Euro plug. True, it's black, but you don't need to look for adapters.
There is nothing interesting on the sides of the body. Once again I want to note high quality materials and manufacturing. This is the case when the thing is simply pleasant to hold in your hands.
The found cable fit like original, the connector clearly matched in size, the contact was tight and reliable.
When turned on, a white LED on the top lights up. Shooting white on white is still a challenge.
Testing
The first test is using USB cable C - USB C, which I use to transfer data from a laptop, I connect my Xiaomi Mi 5X - charging has started successfully.
Load tests
Standard ports - at idle they produce a voltage of 5 volts.
A load of 12.5 Watts at 2.5 A can be easily withstood without voltage drop, which is even slightly higher than the declared value. I will say that in real life, few devices consume current above 1-1.5 A when charging.
The port supports QC 3.0 - easily produces the declared 3 A, with absolutely no voltage drop.
Let's check the operation in QC 3.0 mode - which supports a smooth increase and decrease in voltage in steps of 0.2 V. The minimum voltage that I was able to get at the charging station is 3.76 V
It really changes in steps of 0.2 V and, upon request from the device being charged, you can get any non-standard voltage - for example 7 V, which is needed at the current stage of charging.
Maximum voltage - 12 Volts
As for the load power, the port easily delivers about 18.5 Watts - that’s more than 2 A at 9 V
Accordingly, at 12 V, the load current exceeds the value of 1.5 A. During the tests, the charging station was barely warm, which cannot be said about the electronic load, the fan of which could barely cope with the heat.

Conclusion
Convenient, compact and powerful charging station from a famous brand, with support for fast charging technology. Taking up just 1 electrical outlet, it can simultaneously charge up to 6 gadgets - smartphones, tablets, power banks, or power various devices- IP cameras, universal IR bases and much more.
That's all, thanks for your attention.
Despite the fact that over the past few years, mobile devices have become even more powerful and functional, they still have the same problem - the need for frequent recharging. This is because battery production technology has not yet received a qualitative change towards improvement.
Mobile devices use the same Li-Ion batteries, as several years ago. Perhaps they have become a little more advanced, but their charge lasts for about the same life of the phone (tablet) as before. And now the question is no longer so much about the battery capacity, but about the speed of charging the battery - here the companies were still able to move forward. 
MediaTek, a well-known manufacturer of electronic components, has proposed its own battery charging technology, called Pump Express 3.0. The company claims that this technology can charge the battery from 0 to 70% in just 20 minutes. To connect mobile device it is proposed to use USB Type-C cable.
Thanks to this, a kind of two-way communication is formed, and the phone can “notify” if the battery is already full. In addition, the system automatically adjusts to the battery characteristics of the mobile device.
When charging using USB-C, the current goes directly from the adapter to the battery. The standard charging circuit is not used inside the device. The developers claim that the device will not overheat - there are about 20 various systems device protection. Energy leakage has been reduced by more than 50% compared to the previous charging version.
Invitation to testing gadgets
Dadget invites authors interested in testing our devices and writing an objective review to collaborate. The device remains yours after the review is published. More details about the offer -The technological process does not stand still, and modern phone manufacturers are releasing more and more sophisticated models with many new features. Active improvement of software and hardware functionality leads to the fact that time battery life devices is reduced. Big RAM, powerful processes, multi-inch touch screens and strong cameras - all this contributes to the fact that the batteries are discharged quite quickly. This is why it is important to have a reliable memory. It’s great if the original charger has been preserved, but what if it’s lost or broken? Then buying a new one raises the question of not only preserving the functionality of the phone, but also your own comfort.
Everyone has experienced their smartphone running out of power at the most inopportune moment. This is especially scary when there is sorely not enough time to recharge. At such moments, one grabs the first thing that comes to hand. Charger, connects and the countdown begins. Sometimes the process happens quickly, and often it takes a treacherously long time. The result is sad - after some time there is no connection again. Today we’ll figure out how memory devices differ and how to make the right choice.
Charger type
Before purchasing, many people ask themselves which memory is better to choose: original, analog or universal? Many people buy the original, which means they do not worry about the compatibility of the device with gadgets, the speed and features of charging, as well as various risks (cheap chargers that are sold in tents in markets may well lead to strong heating of the battery). But it is not always possible to buy an original device, then the best option will become a high-quality analogue. It contains a list of compatible device models, as well as specifications, which are identical to the original data.
Power connector
The memory can have different connectors:
The weakest link in the charger is the cable. If it is non-removable, then if it breaks, it is almost impossible to restore the functionality of the device. If it is removable, then the adapter itself, which is plugged into the network, can be used further by simply purchasing an additional wire.
When choosing a charger, it is better to give preference to proven brands. For questionable devices, the cable can reduce charging efficiency by up to 75%. And this is not only a loss of electricity, but also of your time. In addition, such cables can break or come off the connector, which ultimately remains in the device. It leads to short circuit and device failure.
Fast charging
Some charger models have fast charging. She may be:
According to the developers of Quick Charge technology, battery charging can be accelerated by up to 75%. In the first few minutes, smartphones that are compatible with Quick Charge are charged for several hours of use. This is really convenient in the modern rhythm of life - you run into a cafe, plug in your gadget, drink a cup of coffee and leave with a phone with a decent battery charge.
The key difference between Quick Charge 3.0 technology and 2.0 is the presence of the INOV function or intelligent determination of the optimal voltage. Depending on the progress of the battery charge, the required current strength gradually decreases. This allows you to minimize wasted energy during recharging.
Using a special adapter with the Pump Express+ 2.0 function, you can fully charge your smartphone battery 1.5 times faster compared to a standard charger.
Price issue
Today, chargers are available in a wide price range. So, having spent:
from 65 to 300 rubles you can buy branded chargers for devices of various brands ( Sony Ericsson, Samsung, LG, Apple or Nokia). They can be without a wire, as well as with a removable or non-removable wire.
From 300 to 1000 rubles you can purchase universal chargers in a durable case with two USB connectors. They will become an indispensable companion when traveling and Everyday life.
for more than 1000 rubles you will receive reliable and practical chargers from leading brands. A number of models have the Quick Charge 2.0 or Quick Charge 3.0 fast charging function, in which the charging power is increased by voltage rather than current. Which is absolutely safe for the gadget, because... it does not overheat.

Charge can be shared
To car charger Xiaomi Mi Car Charger QC 3.0 You can also connect a special extension cord with additional connectors, allowing people sitting in the back to charge gadgets. Thus, in addition to the second connector in the main device, the charger Xiaomi device It will also have additional connectors for rear passengers and will be able to charge all devices at the same time. Automotive connector Xiaomi chargers(versions with fast charging function) must be used in conjunction with a special extension cord to meet the needs of rear passengers.
A bunch of Xiaomi smartphones are initially equipped with Quick Charge technology, which is actively used by mobile device users. The function replenishes the battery energy in the shortest possible time, so after an hour its performance increases to 100%. To study, we suggest disassembling fast charging version 3.0 to find out everything you need to know!
Quick Charge
Qualcomm Technologies distributes mobile phones the most current innovations, so the first modification of the technology showed that the speed of charging gadgets can be much faster compared to the standard procedure. After one year of development, the manufacturer demonstrated the second version of the option, which speeds up the process by 75%, while highlighting various attributes that can be used additionally.
As of 2015, the function continues to improve and only shows an increase in the speed of energy replenishment. Therefore, at the end of 2017, Xiaomi introduces more than 10 models that are equipped with Quick Charge 3.0.
By activating the fast charging option, more current is supplied to the battery, greatly increasing efficiency. To perform the procedure correctly, the smartphone and charger must correspond to the same voltage. For example, when the device is equipped with the necessary technology with a resistance of 9V/2A, however, using a 1A adapter, the procedure will require much more time.
Another scenario is if a 2A charger is used with a phone for which maximum value 0.7A, the speed of the procedure is not accelerated. However, the device can replenish energy faster, provided that an identical adapter and power supply are used, but with increased voltage. The project website notes that an uncertified product may not correspond to the declared properties.
How does Quick Charge technology work?
The fast charging function adjusts the current supply to the battery of the mobile device at the initial stage of the procedure. Therefore, some smartphones replenish up to 80% of energy in half an hour. Moreover, upon completion of the process, the voltage is not so high, regardless of what modification of the technology is used. Accordingly, the first half of the battery capacity can be filled in a short time, but it will take more than one hour to finish.
What's new in Quick Charge 3.0?
The third modification of the technology increases the speed by 4 times, so compared to the previous version, the results have increased by almost 40%. Manufacturer Qualcomm focuses more on discussing practicality instead of improving performance.
Therefore, the main innovation is the INOV option, which provides an intelligent selection of properties that sets the correct power and energy replenishment time for a specific phone.
Differences between QC 3.0 and previous versions
To determine the main difference, most current version fast charging from predecessors, it is necessary to study their features, after which you can decide that by increasing the voltage, the process time was reduced with each new modification. The highest power rating in Quick Charge 3.0 is almost the same as the second generation – 18 W. At the same time, for batteries with a smaller capacity, the rate of energy replenishment increases, due to which less time is required.
Xiaomi without Quick Charge support
Why does your smartphone not support fast charging? Such questions most often arise from users whose phones do not have the appropriate technology. For example, owners of the popular Xiaomi Mi A1 on pure Android were disappointed by the inability to use Quick Charge. The reason is that it belongs to Qualcomm, so its availability depends on the chipset used in the device. As a result, all the nuances must be taken into account by the developer in the process of designing a new gadget model.
Based on the manufacturer's statements, a certified charger can be used with devices without technology support. There are no problems with this, but you will not be able to take advantage of the corresponding features during charging.
Conclusion
The Quick Charge option has great potential and popularity, since developers are constantly introducing improvements, providing various innovations in version 4. Smartphone owners will be impressed by Xiaomi models using QC 4.0, which are expected to be released in early 2018.
