After we know the electronic products, we can not do without the step of charging. No matter how expensive you are, more advanced products need to be charged. Charging mobile phones is an unavoidable issue for each of us. Whether it is the “elderly era†of big brothers or a variety of smart phones nowadays, the eternal topic of charging is indispensable.
Ancient times:
Nokia N72 Power Adapter
Take the Nokia N72 as an example, the battery capacity is 970mAh, and the screen is 2.1 inches. At that time, the Nokia mobile phone is still using a round-headed charger, and has not yet used the MiniUSB or MicroUSB interface. At that time, there was no special need for charging speed, and the power adapter output provided was only 5V/350mA. This was also the status of the most basic power adapter at that time. Since the battery capacity of the mobile phone was small, the output current was also very rational.
Intelligent era:
After the enlightenment of smartphones and mobile applications, Android and iOS mobile systems gradually approached us. At this time wave after wave of Android smart phones and iPhone also vacated. They all have a feature - a large screen. Compared with the size of the previous mobile phone screens, they are still large screens with a 3.5 inch screen.
HTC G1 power adapter
HTC G1 is the originator of Android phones (there are also ones in Xiao Bian) and uses a 1150mA battery, so the corresponding power adapter has also been upgraded, and the output has been upgraded to 5V/1A, and the power interface has become the MiniUSB interface.
Prosperous times:
After N years of smart phone education for the market, people gradually accepted the essential smartphones in daily life, and they are increasingly relying on smart phones. The mobile phone screen is becoming bigger and bigger, and now the mobile phone is not just a communication tool, but an essential part of everyone's life. Games, video microblogging microblogging microblogging are ultimately accompanied by smart phones, followed by the big screen + big battery, now 5V/1A output current can not meet the growing demand, this time Qualcomm launched Quick Charge1. 0 Technology phones have doubled their output to become 5V/2A output, which also solves a certain charging problem.
Samsung S4 power adapter
However, as the performance of new SoCs continues to increase, the frequency and the number of cores increase, the number of screens increases, and mobile phone battery technology has reached a “bottleneckâ€. Subsequently, Qualcomm introduced the Quick Charge 2.0 technology to increase the output of the previous 5V/2A to the "12V/1.35A or 9V/1.67A or 5V/2A" specifications.
QC2.0 Power Adapter Support
Those wonderful things:
VOOC Flash Charger Adapter
VOOC data line
In addition to the above charging specifications, the OPPO's VOOC flash charge (ear reverberation: charge 5 minutes, call 2 hours) must not be reduced. It can be said that flash charge is the general existence of God, and its specification is also very "violent". His output has reached 5V/5A. Without raising the voltage, the output of the boost current reaches the purpose of rapid charging, and the data line is It also made a special adaptation. The data line suitable for VOCC flash charging will grow longer than the ordinary MicroUSB data line socket, and the data line end of VOOC is 7 pins, and the pin of ordinary MicroUSB data line has only 5 pins.
Samsung Fast Wireless Charger
In addition to the strange chargers, Samsung also has a "black technology" product. With the S6 edge+ and Note 5, the quick wireless chargers listed can almost achieve the same charging efficiency as the ordinary QC2.0, and the output can be achieved. 9V/1.67A. The use of effects can be compared with the ordinary plug-in type rapid impulse feeling.
Now that battery technology has developed into a bottleneck, and in a short period of time, it can't solve the problem of balance between battery life and performance. Manufacturers are constantly trying to speed up charging, allowing users to get a better user experience and make charging wait time. Shorter, this is what everyone wants to see. Before the battery technology has yet to break through, it can only rely on various fast charging technologies and more energy-efficient hardware technologies (some pictures come from the Internet).
