The history of the development of mobile phone chargers, you have seen these mobile phone chargers, indicating that you are old
With the continuous progress of society, people's communication has also undergone tremendous changes. In the early days, our ancestors could only carry out simple face-to-face exchanges in sign language. Later, after the words appeared, the human way of transmitting information was gradually enriched. Later, a postman appeared, rode to each station, changed horses, and finally sent the letter; the pigeons spread their books, tied their letters to the legs of the pigeons, and then they flew away. The pigeons would return to their original place and write to them. Where do you use the pigeons? The bonfire relays information, lights, etc. However, these are very labor-intensive and extremely slow.
Until the emergence of telegraph telephones in modern times, people’s contact methods have undergone a qualitative leap until the emergence of modern mobile phones and the Internet has brought the society into the age of the information explosion, even if it is a modern smartphone with a fairly complete function. In the non-stop renovation. While these mobile phones are constantly innovating, mobile phone chargers are constantly being updated. So what are the changes that mobile phone chargers have undergone?
The earliest emerged was the big brother we often saw in the Hong Kong TV series. The Big Brother charger is just as bulky and inconvenient as the Big Brother.
Later, there was a universal charger. The universal charger was lighter than the Big Brother. It had to be removed from the battery to charge it, and the battery had to be removed and the copper contacts were inevitably worn. Therefore, the battery life would be reduced.
Then came the miniUSB charger and Nokia's round charger. After that, the shape of the charger is basically fixed. But the charger's internal circuitry and charging line interface has been changing.
Then came the microUS charger, which was commonly used on Android phones. The microUSB charging cable already had the ability to transfer data.
Later, Type-C chargers and Apple's lightiing chargers emerged. The chargers of the two types of connectors not only changed the disadvantages of the front and back of the charger, but they can be charged on either side, and the charging speed is greatly improved. In one hour, the mobile phone can be fully charged, and the speed of transmitting data is also greatly improved compared to the microUS charger.
Later, wireless chargers appeared again. Although wireless chargers have not yet been popularized, its emergence undoubtedly brought a new revolution in the field of mobile phone charging.
