This weekend, the self-media article "I was threatened to delete the manuscript by Ding Lei" was screened in the circle of friends. The cause of the incident was that after the media "Fisheye Observation" saw a proposal on a unified charging port by Ding Lei, a member of the National Committee of the Chinese People's Political Consultative Conference and CEO of NetEase, he wrote an article "Why Ding Lei is Wrong". The main view is that "the unified charger interface will stifle innovation, and the government should not overstep its bounds", and at the same time pointed out that Ding Lei "more than once called for administrative intervention in the market" and "as a well-known entrepreneur, the level is worrying" and so on.
On January 14, the author posted that NetEase threatened to delete the manuscript, and then Ding Lei wrote a letter to apologize and respond to questions about whether the unified charging port standard would hinder the industry's innovation. As soon as the response came out, many netizens praised Ding Lei for having a very pattern. Some netizens commented, "Do not avoid problems, use communication to resolve confrontation, this wave of public relations deserves 90 points." "So who is wrong in this matter?" For a while, there is a lot of discussion, let's first understand the evolutionary history of mobile phone charging ports, and then judge which is right and which is wrong!
With the continuous upgrading of mobile phones, the battery capacity continues to increase, and the charging ports of mobile phones and mobile phone batteries are also constantly evolving. In that era, a variety of charging ports made the "clip-on" universal charger in the following figure popular all over the world, and I believe that the post-70s and post-80s will not be strangers.
Circular interface
The earliest charging interfaces were round and most commonly used on Nokia phones.
This circular interface is available in large and small sizes and can be plugged in and out at will. However, because this interface has a single function, most of them are only used for charging and cannot transfer files. Coupled with the circular design, in the long-term insertion and removal process, it is easy to have problems such as loose interface and poor contact, so the circular interface gradually disappears on the mobile phone.
Flat wide interface
This flat and wide interface is mainly applied to Samsung Anycall series mobile phones, which is the exclusive interface type customized by Samsung for its own mobile phones, and it is almost extinct. There are still some at home, guess you should not be young.
The earliest iPhone to iPhone4s series devices all use a 30-pin Dock interface, which is also a long flat and wide form factor. This kind of interface, large size, poor transmission speed, compatibility and openness are not very good.
Mini USB port
This interface, also known as mini USB, is T-shaped, small in size, and has excellent anti-mis-insertion performance. Although many mobile phones are no longer used, some mobile hard disks, digital cameras, elderly machines, mobile POS machines, and PSP game consoles are still used, after all, they are small.
Micro USB interface
The Micro USB interface is the next-generation specification of Mini USB, a portable version of the USB 2.0 standard that is compatible with USB 1.1 and USB 2.0. It's smaller than Mini USB, transfers faster, and has up to 10,000 mating lives and strengths, but it can only be inserted on one side. Most of the mainstream flagship mobile phones now abandon this interface, and only some 100-yuan, thousand-dollar smart phones are still in use.
Lightning interface
Starting with the iPhone 5, Apple replaced the new Lightning interface, which is smaller, more feature-rich, and supports front and back insertion. This interface supports up to 2.4A current carrying capacity and transfer speeds to USB 2.0 standards. Although the standard is a little low, the actual performance and experience are very good, and it is currently the standard interface of the iPhone phone.
Type-C interface
After Micro USB, Type-C is another type of interface that is widely used in Android smartphones. Type-C interface first appeared in Nokia N1, in 2015 was used on Apple's MacBook, the first domestic crab is LeTV super mobile phone 1. Today, the Type-C interface has become the standard interface for flagship mobile phones such as Huawei, Xiaomi, and OPPO, which can be described as promising.
Why are major mobile phone brands keen on the Type-C interface? This has to be praised for its excellent performance and experience.
1, thinner, catering to the light and thin design needs of mobile devices, can be inserted forward and backward;
2, the maximum charging speed supports 5A charging, charging power up to 100W;
3. In terms of transmission rate, the fastest reaches 10Gbps per second;
4, the expansion function is powerful, can connect external USB devices, connect large-screen monitors, projectors...
On the issue of the unification of mobile phone charging interfaces, the Type-C interface is undoubtedly the most vocal, after all, the strength is obvious to all.
Is there a mistake with the charging port of a unified smart electronic device?
Now, we focus on Ding Lei's proposal, for Ding Lei's problem of the unified port of the same smart electronic device charger, is he really wrong? Let's see what netizens say.
At present, the charging interface is not uniform caused by the inconvenience of borrowing a charger, a data cable is eager to connect three connectors, T ports, flat T ports, MicroT ports, C ports, different configurations of different devices, bringing great inconvenience to life, and indeed many people will also encounter pain points in their lives.
It can be seen that the call for users to unify the charging port has been very high. Some netizens believe that the idea of a unified charging interface is very effective, which can improve the utilization rate of products, not only bring convenience to life, but also reduce e-waste and save resources, which is conducive to our country to achieve low-carbon green good methods.
For the problem of unified charging ports, the European Union has long proposed to require legislation to unify the charging interface of electronic products. More than a decade ago, 14 mobile phone manufacturers, including Apple, agreed to a unified power standard under pressure from the European Commission to solve the power problem. The European Parliament has been pushing for a unified interface for years, and governments will have a year to introduce new rules after the EU Parliament reaches an agreement with EU countries.
However, any implementation of a unified policy may hurt the interests of small and medium-sized enterprises, such as increasing the cost of product certification. Therefore, in the process of driving any innovation process, controversy, even friction, is quite normal. Discussing things, responding positively to problems in a timely manner, not running away from the pot is the attitude we want to see.
