fast charging ( Quick charge) is a technology for increasing the standard USB specification voltage and current at the output of the power supply to speed up the charging of the battery of a phone or tablet. Fast charging modes vary by technology. Support for fast charging implemented in smartphones and tablets samsung galaxy, ASUS ZenFone, Google Nexus and a certain number of other devices.As is known, standard USB The 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 the device 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 iPad generation required, i.e. 5 V and 2 A. When connected to regular USB port iPad computer did not even show that charging had begun. Charging, of course, went on, but so slowly that it was impossible to charge the tablet even for a whole day.
Today, most smartphones can be charged with 5W chargers with USB output, and tablets can use up to 2.1A from a 5V charger. How many Amperes to take from the USB port of the charger is decided by the battery controller of a smartphone or tablet, so it is quite safe to connect a smartphone to a 5V / 2A charger - the controller uses as much current as it needs to charge.
So, in order to quickly charge modern gadgets, like a smartphone or tablet, well-known manufacturers mobile platforms developed special technologies.
Qualcomm introduced the fourth version of the technology Quick Charge 4, and MediaTek, in turn, presented two specifications Pump Express and Pump Express Plus.
The meaning of these technologies is to charge the battery of a smartphone or tablet as quickly, efficiently and safely as possible. To support each technology, 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.
In each of these technologies, the same techniques are used - either increasing the current, or increasing the voltage, or both. Qualcomm became a pioneer in fast charging - in February 2013, the technology was introduced Quick Charge 1.0. Devices that support this technology are capable of charging at 5 volts and using 2 amps. As you can imagine, tablets with Quick Charge support began to charge as fast as the iPad, and smartphones almost twice as fast as the rest.
Next generation Quick Charge 2.0 allowed to use increased voltage up to 12 volts for charging. More precisely, for QC 2.0, you can choose from three fixed voltages: 5 V, 9 V and 12 V (optionally, 20 V are also available charging device). At the same time, the maximum power of the power supply can reach 18 watts.
Quick Charge 3.0 appeared in devices based on Qualcomm Snapdragon 820, 620, 618, 617, 430 and newer processors. Differs in the increased efficiency and intelligence. A compatible charger is capable of dynamically changing voltage from 3.2V to 20V in 200mV steps. The current strength also changes dynamically. Moreover, changes in the configuration of the power supply 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 is noticeably slower. The power of Quick Charge 3.0 power supplies remained at the same level - 18 W maximum, however, it 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 accurate figures sound like this: a 3300 mAh battery was charged up to 60% in 30 minutes. Impressive result, isn't it? In addition, the manufacturer claims that Quick Charge 3.0 is twice as fast as the first generation of Quick Charge, which, in general, is logical. We also note that all three generations of the 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, a first generation power supply will not be able to charge as fast as a QC 3.0-enabled power supply.
With an announcement Qualcomm processor Snapdragon 835 has information about Quick Charge 4.0. 20% faster and 30% more efficient. Able to give 5 hours of work in 5 minutes of charging.
Note that the technology implemented in chargers is completely undemanding to the type of cable - you can use ordinary cables USB type micro B, USB Type C, or cables with a proprietary connector from the gadget manufacturer. It should also be noted that fast charging is only fast up to about 80% charge. And up to 100% the battery will be recharged for a long time, in order to avoid damage to the battery.
As for 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 of this does not change. Pump Express allows you to charge devices using a voltage of 3.6 - 5 Volts and with a charging current of not more than 2 Amperes. 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 Amps. True, MediaTek does not say anything about 5 Volts and 3 Amperes. 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 amperes. An 18-watt charger, in particular, is included in the delivery of some ASUS smartphones Zenphone 2.
In Samsung, a similar technology for top smartphones Galaxy 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 launched a dedicated charger. It can deliver 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 when some smartphones with support for USB fast charging technology are equipped with chargers with characteristics of 5 Volts and 3 Amperes. For example, such chargers can be found bundled with and from LG.
Knowing about availability huge amount 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 away from USB port all the necessary and available charging current, respectively, can be charged faster than from a regular charger with more modest characteristics. The conclusion, of course, is theoretical, therefore it does not claim to be the absolute truth.
In addition, the specification of the new connector and cable suggests 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 watts - overkill for the vast majority of smartphones and tablets. In practice, we will observe the implementation of various fast charging functions (including those described above) using a standard USB cable Type C, as well as expanding the range of USB chargers with increased output current.
Hi all!
I present to your attention the "extension cable" of the IR remote control for home appliances.
In short - it works, its money is worth it.
More details - please under cat.
I thought in what category to put it, I decided that once it was bought to control the muses. the center, then let it be audio equipment. Of course, anything can be controlled, which is usually controlled by household IR remotes - audio, video, television, computers, etc.
The main purpose of the device is to forward the infrared (IR) signal to the “dead zones”, where the regular remote control does not finish.
I have, for example, recently purchased music. the center found a place only on the refrigerator, and the speakers are exactly in front of it and completely cover the window of the standard IR receiver, so it’s impossible to use the sloth remotely.
To correct this unfortunate misunderstanding, this device was purchased. The principle is as simple as two fingers - we mount a small receiver in a conspicuous place where the remote control “shoots”, from it the wires go to the IR emitters that need to be fixed on the controlled device, exactly above the IR receiver window (at least that’s what it says in the description on site). Both the receiver and transmitters have an adhesive surface covered with paper.
Next, you press a button on the standard remote control, the signal goes to our receiver, is transmitted by wire to the transmitter, and there it is re-emitted directly to the receiver of the controlled device.
I draw your attention - this device does not know anything about the format of IR packets (as long as they remain in a certain range), or about control codes and so on, and it is absolutely indifferent to how and what you are trying to control.
Those. it's stupid Layer 1 device;)
This “extension cable” is powered by USB, which is especially good, because. now many audio-video devices have a USB port, which eliminates the fuss with extra sockets and wires. I plugged mine into the USB port of the music. center - works without problems.
The result is highly dependent on your native remote control and its power / range, but that the device works as stated and performs the functions assigned to it is obvious.
Arrived in a small paper bag, inside two components in their plastic bags.
There were no packages, boxes, instructions or anything else.
Package
This is what it looks like in real life: 
The upper part is a receiver with a USB power connector and a 3.5mm female mini-jack connector for a bunch of transmitters.
The bottom one is a bunch of IR emitters and a male mini-jack 3.5 connector.
The length of the wire "USB connector" - "Receiver" - 2 m,
The length of the wire "Receiver" - "mini jack 3.5" - 1.9 m,
The length of the wire "mini jack 3.5" - "IR emitters" ~ 1 m.
This is what it looks like when installed:
Receiver - hooked in a high place on the cabinet: 
By the way, the receiver is very sensitive, it easily receives the signal reflected from the white wall. Although here again - it depends on the remote itself.
It has a red LED that flashes when a signal is received.
Emitters (3 out of 4): 
Here is such a moment - the emitter itself is very small and the emitting LED is located deep in the center, so you need to position it exactly opposite the receiver: 
I stuck three out of four because it was difficult to crawl up and stick it neatly. The adhesive surface on the emitters, by the way, is very sticky and worked even after three re-gluings. They were torn off from the smooth plastic of the receiver with difficulty.
Measured current consumption in idle mode
(here I wanted to insert a picture, but my voltage meter showed zeros)
and when pressing the buttons on the remote control: 
3 mA - at the margin of error of the voltage meter.
By the way, I want to note that on the same eBay there are similar ones, with 2-4 receivers and up to 8 transmitters. I thought to take one (put a second receiver in the bedroom), but they are more expensive, have an additional central unit and require full power from the outlet / adapter.
But if anyone needs an extended coverage area, they are worthy of consideration.
A PLUS:
+ compact, lightweight, necessary minimum wires
+ USB powered
MINUS:
- in my version it is impossible to connect additional. receivers, i.e. not expandable (at least without a file)
- requires very precise positioning of the transmitter relative to the receiver
CONCLUSION:
* works, worth the money, I recommend to buy.
Good luck.
