Hi all!
I present to your attention a review of the “smart” charger
Briefly: it works, in some cases it charges really faster
More details under CAT
A little background on the “purchase”:
Since I am the author of a website related to reviews of online purchases, managers of various stores periodically contact me in order to “push” something for which this moment the store makes a bid.
This time, the “smart” charger Tronsmart Quick Charge 2.0 18W turned out to be “shoved through”, which, according to the manufacturer, should charge batteries 75% faster 
As a result of laboratory tests using a 3300mAh battery, it was found that the Tronsmart 2.0 charger charges it to 60% in 30 minutes, while when using a conventional charger (5 volts, 1 ampere) the battery was charged by 12% in the same time .

The kit includes instructions for English language, 2 meter USB cable and the charger itself.
It is worth noting that the USB cable is quite thick and inspires confidence.
The charger is not much larger in size than its “stupid” counterparts
The characteristics are indicated on the end (the same as those stated on the product page)
✔Testing
Due to the fact that there is no opportunity to test with devices that support qiuck charge technology, I offer a short video from the network demonstrating the operation in comparison with the “stupid” 1A/5B and 2A/5B chargers

Laboratory measurements are of course good, but how often do you connect the battery to charge from the USB port directly? All modern devices, be it a tablet or a phone, have a controller installed that is responsible for ensuring that there is no overcharging and limits the maximum charge current.
Since the manufacturer decided to compare this subject with a 5V 1A charger, I took the same
First, I tried charging the powerbank.
In half an hour, it absorbed 800 mAh from “smart” charging, while from “stupid” charging it only absorbed 600 mAh, the difference is small, but there is a slight increase in charge speed.
Now “test with an average smartphone.” In the same half hour, the old Jiayu G2 absorbed 310 mAh from the “smart” charger, and, oddly enough, 340 mAh from the regular one.
With smartphones that do not support technology fast charging, a miracle will not happen - the charging time will be comparable to the charging time from an ordinary good 2A charger.
The maximum current that I was able to see on the tester was 2A. During operation, the device does not make any sounds, heats up slightly, and phantom clicks do not appear on charging devices.
I wanted to show the insides, but the assembly was too good, no matter how much I picked, I couldn’t gut it...

Planning to buy +1 Add to favorites I liked the review 0Even if you are often near a power outlet, a smartphone that runs out at the wrong time can create many inconvenient moments. What to do if it’s time to go out and the battery hasn’t had time to charge? Or when we forgot to charge our gadgets in the evening, and in the morning they greet us with warning signs of discharge? Of course you can always use external battery, but you also need to have time to charge it. And it usually takes so long to charge...
Manufacturers of batteries and gadgets are well aware of this problem - and successfully solve it with the help of “fast” charging technologies. Let's take a quick look at modern technologies fast charging, especially as they continue to develop rapidly in 2017. At MWC 2017, Meizu presented the fourth generation of its fast charging technology – Super mCharge.
Super mCharge
Super mCharge technology allows you to fully charge a smartphone with a 3000 mAh battery in just 20 minutes. How fast is it? The Meizu prototype equipped with this technology was 11 times faster than iPhone charging 7 Plus and was 3.6 times faster than the Samsung Galaxy S7 Edge. Of course, in 5 minutes you can charge the gadget by 30%!
To achieve this result, the high voltage direct charge (HVDC) method is used. The Super mCharge power adapter produces a voltage of 11V at a current of 5A. This means that the maximum transmitted power reaches an impressive 55 W. A regular charging cable cannot transmit such power - so to use Super mCharge you will need not only a smartphone and an adapter that supports this technology, but also a separate high-power cable.
A separate plus is that the heating temperature of the battery case during such “turbo charging”, according to Meizu promises, will not exceed 39°, which will allow you to comfortably work with the smartphone, even while charging from the mains.
Quick Charge
For several years now, Qualcomm has been releasing chips that are compatible with its own Quick Charge fast charging technology. Its support is provided either by using a separate chip in the system or a compatible Snapdragon chip. For this reason, Quick Charge technology is supported not only Android smartphones with a Snapdragon chip, but also separate external batteries – in particular models from Xiaomi.
In 2018, the fourth generation of Quick Charge 4.0 appeared, compatible with USB protocol Power Delivery (USB-PD) via port USB Type-C. But also previous versions Quick Charge does not lose its relevance - it allows you to reduce battery charging time by up to 75%. Due to the popularity of Snapdragon chips, support for this technology can be found in many flagships from various brands. Quick Charge 3.0 technology is backward compatible with previous ones - so if your gadget supports Quick Charge 2.0, a charger with version 3 will work with it.
Quick Charge adapters charge your device faster by allowing the device to accept more voltage and current. If you connect Quick Charge to an old device, nothing bad will happen, but the gadget will charge at the same rate. As with Super mCharge, fast charging requires not only support for the technology on your gadget, but also an appropriate charger. You can use a regular cable - and you can quickly charge not only your smartphone, but also an external battery!
Super Charge, Turbo Charge, Pump Express, RapidCharge, FastCharge, VOOC Flash Charging
Each manufacturer strives to implement its own fast charging option for its devices. Alas, in anticipation of the “nano” or “graphene” battery technologies promised to us by scientists (which, in theory, can be charged instantly), all current solutions are based on a single technical solution - increasing the throughput power and current strength.
As an example of an alternative solution, we can mention OPPO with its proprietary VOOC Flash Charging technology. Thanks to the eight-pin battery, each of the internal cells is charged in parallel, with a current of 4.5 amperes and a voltage of 5 volts.
Pump Express works similarly to Quick Charge, but only with MTK processors, and Super Charge from Huawei boasts high-speed charging records (but only in its flagship devices).
Instead of conclusions
When choosing fast charging technologies, ask which ones your gadget supports. And if you have an iPhone or your smartphone does not support any of them, it doesn’t matter, just choose a suitable external battery that supports fast charging, supplement it with the necessary network adapter and you will definitely not be left without communication at the most inopportune moment. And if you already have an external battery, choose a charger that supports a charge current of 2.1A, so your iPhone will charge faster.

Fast charging (Quick Charge) is a technology that increases the standard USB specification voltage and current at the output of the power supply to speed up charging the battery of a phone or tablet. Fast charging modes vary depending on the technology. Fast charging support is implemented in smartphones and Samsung tablets Galaxy ASUS ZenFone, Google NEXUS and a certain number of other devices.As you know, a standard USB 2.0 port supports powering devices up to 2.5 W (5 V and 0.5 A). In turn, the USB 3.0 port can provide power to devices with a power of 4.5 W (5 V and 0.9 A). In my time Apple company set the trend for charging from more powerful power supplies - the first generation iPad required, that is, 5 V and 2 A. When connected to a regular USB port on a computer, the iPad did not even show that charging had started. Charging, of course, was going on, but so slowly that it was impossible to charge the tablet even in a whole day.
Today, most smartphones can charge from 5-watt USB chargers, and tablets can use up to 2.1 A from a 5-volt charger. How many Amperes to take from the USB port of the charger is decided by the battery controller of the smartphone or tablet, so it is quite safe to connect the smartphone to a 5 V / 2 A charger - the controller uses as much current as is needed for charging.
So, in order to quickly charge modern gadgets, such as a smartphone or tablet, well-known mobile platform manufacturers have developed special technologies.
Qualcomm has already presented the fourth version of the technology Quick Charge 4, and MediaTek, in turn, presented two specifications Pump Express and Pump Express Plus.
The point of these technologies is to charge the battery of a smartphone or tablet as quickly, efficiently and safely as possible. To support each technology, the mobile device, including the battery controller, must be compatible with it. Of course, you need a certified charger that can “speak the same language” with the battery controller of your smartphone or tablet.
Each of these technologies uses the same techniques - either increasing the current, or increasing the voltage, or both. Qualcomm became a pioneer in fast charging - the technology was presented in February 2013 Quick Charge 1.0. Devices supporting this technology can be charged at 5 Volts and use 2 Amps. As you can imagine, tablets with Quick Charge support began to charge as quickly as the iPad, and smartphones - almost twice as fast as others.
Next generation Quick Charge 2.0 made it possible to use increased voltage for charging up to 12 volts. More precisely, for QC 2.0 you can choose from three fixed voltages: 5 V, 9 V and 12 V (optional, 20 V chargers are also available). Wherein, maximum power The power supply can reach 18 W.
Quick Charge 3.0 appeared in devices based on Qualcomm Snapdragon 820, 620, 618, 617, 430 and newer processors. It is characterized by increased efficiency and intelligence. A compatible charger can dynamically change voltage from 3.2 V to 20 V in 200 millivolt increments. The current strength also changes dynamically. Moreover, changes in the power supply configuration continue during the charging process - the current decreases as the battery is charged in order to save its resource. In particular, because of this, the last 20-30% of charging occurs noticeably slower. The power of Quick Charge 3.0 power supplies remains the same - 18 W maximum, but charges gadgets a little faster, due to better optimization process.
As you can see, the advantages of the technology are obvious - according to the manufacturer, in 30 minutes you can charge your smartphone by more than half. More precise figures are as follows: a 3300 mAh battery was charged to 60% in 30 minutes. Impressive result, isn't it? In addition, the manufacturer claims that Quick Charge 3.0 works twice as fast as the first generation Quick Charge, which is generally logical. We also note that all three generations of technology are backward compatible, that is, a power supply of any generation will be able to quickly charge a device of any generation. Of course, the first generation power supply will not be able to charge as quickly as a power supply that supports QC 3.0.
With the announcement of the Qualcomm Snapdragon 835 processor, information also appeared about Quick Charge 4.0. 20% faster and 30% more efficient. Capable of giving 5 hours of work in 5 minutes of charging.
Note that the technology implemented in chargers is not at all demanding on the type of cable - you can use regular USB Type micro B, USB Type C cables or cables with a proprietary connector from the gadget manufacturer. It should also be noted that fast charging is only fast up to approximately 80% charge. And it will take a long time to charge the battery to 100%, to avoid damage to the battery.
Regarding fast charging technologies MediaTek Pump Express and Pump Express Plus- Little is known about her. More precisely, there are very few smartphones and tablets, as well as chargers themselves, that support this technology. The essence does not change from this. Pump Express allows you to charge devices using a voltage of 3.6 - 5 Volts and with a charging current of no more than 2 Amps. That is, this technology is designed to compete with Quick Charge 1.0. In turn, Pump Express Plus allows you to use various voltages of 5 - 7 Volts, 9 Volts and 12 Volts, and the output current can reach 3 Amperes. True, MediaTek says nothing about 5 Volts and 3 Amps. But there is a mention of 9 V and 1.67 A (15 W), as well as the most powerful block power supply 12 V and 2 A (24 W).
* - The list is for informational purposes only. There is no exact list of compatible devices, details may appear.
There are other USB fast charging technologies, for example. The technology allows you to charge devices under a voltage of 9 Volts with a current of 2 Amps. An 18-watt charger, in particular, is included in the delivery package of some ASUS smartphones ZenFone 2.
In Samsung, similar technology for TOP Galaxy smartphones Note 4, Galaxy Note Edge, Galaxy S6, Galaxy S7, Galaxy S6 active, Galaxy S6 edge, Galaxy S7 edge, Galaxy S6 edge+ and Galaxy Note 5 have named and released a special charger. It can produce a voltage of 5 or 9 Volts and a current of 2 or 1.67 Amps, respectively.
In general, given that the “normal” voltage for USB devices is 5 Volts, it seems quite logical that some smartphones that support USB fast charging technology are equipped with chargers with 5 Volt and 3 Ampere characteristics. For example, such chargers can be found bundled with and from LG.
Knowing that there are a huge number of and, some of which are capable of delivering up to 2.4 Amps per USB port, it is difficult to convince yourself of the need to purchase expensive certified chargers. After all, it is obvious that smartphones and tablets that support fast charging technologies will be taken from USB port All necessary and available charging current, accordingly, can be charged faster than from a standard charger with more modest characteristics. The conclusion, of course, is theoretical, and therefore does not claim to be the absolute truth.
We add that the specification of the new connector and cable assumes the ability to use a maximum current of 5 Amps per connector and 3 Amps per standard cable. In theory, at 20 Volts you can reach 100 W - excessive for the vast majority of smartphones and tablets. In practice, we will see the implementation of all kinds of fast charging functions (including those described above) using a standard USB Type C cable, as well as an expansion of the range of USB chargers with increased output current.
Recently, support for Quick Charge 3.0 has often been found in the characteristics of mobile devices - find out why this technology is useful.
In modern conditions, when social media, Internet access and mobile devices In general, they play an increasingly important role in personal life and at work; it is difficult to do without a smartphone or tablet, even for a few hours. The desire of users to always stay connected and depend less on a power outlet has prompted mobile manufacturers to use more powerful batteries and therefore fast charging functions to charge these batteries as quickly as possible.
How does fast charging work?
Fast charging is based on the use of more high voltage. However, both the current and voltage must be compatible with both the mobile and the charger. Otherwise, the speed will remain the same, but there may be a risk of overheating. We discussed the issue of using non-native power supplies in more detail in.
What is Quick Charge 3.0?
Last fall, the American manufacturer Qualcomm presented Quick Charge 3.0 technology, which is currently supported by proprietary chipsets Snapdragon 821, 820, 620, 618, 617 and 430. Compared to the very first version of Quick Charge 1.0, charging speed has increased by 40%, which is four times faster than normal mode. However, the difference in speed with its predecessor, Quick Charge 2.0, is not so great. So what is special about the third generation?
Advantages
An innovative step was the introduction of the INOV (Intelligent Negotiation for Optimum Voltage, or “Smart Determination of Optimum Voltage”) function. New technology allows you to determine and dynamically adjust the optimal output power directly below this device and stage of the nutrition process. Moreover, the choice of supported voltage indicators has increased - now it is available from 3.2 to 20 V with a minimum change step of 200 mV.
Due to this optimization, the coefficient of wasteful energy expenditure is reduced. This, in turn, not only makes charging more efficient, but also prevents the battery from overheating. This means that the battery in your mobile gadget will last much longer. According to the manufacturer, Quick Charge 3.0 is 38% more energy efficient than the second version of this technology.
In addition, Quick Charge 3.0 includes support for fast charging via universal, which more and more smartphone manufacturers are switching to.
Conclusion
Thus, the main feature of Quick Charge 3.0 was not so much the charging speed, but the “ability” to save energy. Currently, all flagship smartphones produced on the basis of Snapdragon processor 820/821, and some mid-priced devices.
