In the youth of all middle-aged people, there is a universal charger.
It works at your bedside to add brilliant and colorful lighting effects to your dreams; When charging is complete, it will even emit a resounding **.
Ignoring the phone brand and battery model, it bridges the gap between the original and the imitation phone, and only two small contact pins can continuously inject power into modern life.
Why has the universal charger that was once so popular and accessible to everyone disappear?
Top universal charger.
There are also complaints that there are too many types of charging connectors, which is too troublesome, and you need to prepare several charging cables with different interfaces at home.
You would have gone crazy 20 years ago!
Twenty years ago, the domestic mobile phone market was turbulent, and many mobile phone brands entered the market, and the types of charging interfaces of various manufacturers were also different.
At that time, when you go to someone's house and want to charge your phone, the owner may throw you a bunch of charging cables of different colors: Hey, let's see which one is right for you? (It is also possible that a match is not found in the end).
Then the high school students of that year got into action.
In 2002, Mr. Chen, a student from Henan, didn't want to fiddle with a bunch of charging cables anymore, so he decided to build a charger that would fit all mobile phones.
Where to start? Some mobile phone charging ports are long, some are trapezoidal, and some are round, and there is no one shape of charging head that fits all charging ports.
Then take out the phone battery and charge it directly!
At that time, mobile phone batteries were replaceable, and everyone got into the habit of carrying one piece with them. Based on this idea, Chen invented a universal charger to solve the battery charging problem.
In 2003, the universal charger was launched and immediately became a popular necessity at home and when going out.
The first hundreds of thousands of universal chargers were sold out within three days. Later, there were too many factories that produced universal chargers, and the specific sales volume could not be accurately calculated, but the popularity is not to mention one per person, at least every household has one, right?
In addition to being popular in China, this delicacy has also been exported overseas and has become a Chinese specialty.
I didn't buy a proper charging cable, so the salesperson gave me a universal charger. So I never bought another charging cable. ”
Oops, dead memories hit me! I've used it and now I feel old. ”
My friend calls it the 'Crab Charger'. "I still keep them somewhere in the house. "I hope this thing still works. ”
However, Chen also performed well, invented the universal charger, not only applied for a patent, but was also recommended to Tsinghua University.
She disappeared unexpectedly.
Think about it, when did this treasure, which is so loved by people at home and abroad, start to disappear?
Let's start with a specific point in time: 2007.
That year, in the chaotic mobile phone market, a dominant mobile phone brand emerged, which is today's "arcade" Apple. One of the designs is astounding: the battery is not removable!
There are different views on why this is the case. Some say it's for safety, some say it's because the phone is thin and light, some say it's for heat dissipation, and some say it's to prevent battery emulation. Share the pie. We will not discuss this today. In short, the integrated design of battery and fuselage quickly became popular and gradually monopolized the market.
Would you go to the mall and buy a phone with a removable battery? Sorry, we don't have any!
The battery cannot be removed, and the universal charger naturally cannot nail the positive and negative poles of the battery, and unfortunately withdraws from the world stage.
Of course, there are many factors that contribute to the obsolescence of universal chargers, in addition to the fact that the battery is not removable.
First of all, 20 years ago, you could only use your phone to text and type**, and you didn't have to carry it with you when you went out. Today's smartphones are almost like human prosthetics. Can you stand to take off the battery to charge it and not touch your phone for hours?
Secondly, even if you can tolerate being separated from your phone for a while, the Magnum charger won't help. Today's smartphones have much larger battery capacity than their phones 20 years ago, and they can be fully charged in just over an hour with the original charger, and if you use a low-power charger that is common to older phones, you may need to charge it overnight. It's embarrassing that the charging speed is not as fast as the consumption.
Third, with a few big brands accounting for the majority of the mobile phone market, the shape of the mobile phone interface is gradually shrinking. If you look at the shared charging treasure on the street, in general, the three-tailed one can cope with all mobile phones.
In short, one day in more than a decade, you no longer remember the universal charger at home, and you never looked for it.
There is still one breath left.
Although the universal charger is already an antique for people of age and can be seen as an electrical coil for anti-mosquito traps, in reality it is like a rare animal that still lives in corners that are difficult to find.
At present, a universal charger has been sold for 60,000 yuan on a shopping software, and more than 100 people have purchased it within 24 hours! What do you think they're buying these things for?
While smartphones can replace half of all appliances, some people only prefer cameras and CDs. According to buyer reviews, more than half of customers buy it to charge their cameras and CD**s. Hey guys, I forgot that these two things need batteries.
Some nostalgic buyers used Magnum to load more than 120 years ago, and I used to charge my phone just to see what's going on in my inbox. Are you thinking?
Some magical uses that are difficult to classify.
There are also reckless and intelligent young people who cannot surpass me. I lost the charging compartment of the wireless earbuds and used the universal charger and the ear plug-in charging contacts directly, and it worked!
Finally, there is a safety warning.
The ordinary 3C certified universal charger is safe, but the wild charger is easy to wear out, and if it is short-circuited, it may also cause disaster. Don't use them!
But even if you are using a regular universal charger, you should pay attention to whether your battery and appliances have settings for stable charging current and voltage (called "current limit protection" in the manual). If so, you can ruin hundreds or thousands of electronics with a multi-dollar universal charger if you don't have the so-called universal charger without it, it's a waste! Technology universal charge
