Evolution of mobile phone charger

Original title: evolution of mobile phone charger
Mobile phones and chargers
It's like a pair of close friends
Even after several changes
Still do not abandon
Remember the "clip on" universal charger that once swept the world? With the development of science and technology, smart phones choose the design that the built-in battery can not be removed. Finally, they are shot dead on the beach by the tide of the times, leaving us only memories.
Today, let's talk about the development history of mobile phone charger.

1.era of blooming flowers
The early mobile phone charger is an era of blooming flowers, but it only has the function of charging. Mobile phone manufacturers have designed their own charging ports to be unique: round, flat, long, short Various models and specifications are not compatible with each other.
One of the most typical is Nokia's round head charger. If you don't have your own charger, it's fate that you want to borrow a mobile phone charger. Fortunately, mobile phones in that era only had simple functions such as call, SMS and 2G network, which consumed less power.


2. start thinking about data transmission ·

When MP3, MP4 and other digital equipment products become popular because of their low price, users begin to be keen on audio-visual entertainment products. At this time, the charger is no longer just satisfied with charging.

Starting to focus on the data transmission between different devices, a small "Mini USB" "t" type charging socket came into being. This kind of charging port is narrow at the top and wide at the bottom, with good error prevention effect, and has both charging and data transmission functions. It has been widely used in digital cameras, mobile phones, mobile hard disks and other electronic products.
Mobile phone charger finally ushered in the unification
3. faster, smaller interface ·
With the continuous upgrading of smart phones, the next generation of "Mini USB" specification is "micro USB", which is now called "ordinary mobile phone charger".

This kind of charging port has smaller volume, faster data transmission speed and longer service life. It also supports USB and OTC functions and can be used for data exchange between mobile phones and USB flash drives. It soon became the mainstream charging port of mobile phones and is still active in some low-end smart computers.
This period began to have the concept of fast charging
4.another change ·
The advertisement brainwashed by "charging for five minutes, talking for two hours" is now the fourth generation charger with type-C interface as the carrier.
From the user's convenience, the type-C interface is smaller, faster to transfer files, supports fast charging (up to 100W power), and front and back insertion, so as to avoid the wrong direction and damage of the socket like micro USB in low light environment.
At present, it is the standard interface of flagship Android phones (Xiaomi, Huawei, etc.). Its application scope is not limited to mobile phones, some computers and high-end electronic products have also been used, and its applicability is particularly wide.
If you think this is the perfect charger now, you are wrong!
Now comes the black technology for this Gan Gan charger.
It is the third generation of new semiconductor materials synthesized by artificial synthesis, using Gan Gan components. The charger is not only small in size and light in weight, but also has more advantages in heat generation and efficiency conversion than ordinary chargers.


Looking back at the historical evolution of chargers, we find that the charging speed of chargers is faster and faster, the capacity of mobile phone batteries is larger and larger, but our charging frequency is also higher and higher. Go back to Sohu to see more
