Fan Jin and Shen Tao also looked at Wang Cheng, obviously the things in Wang Cheng's hands also attracted the two of them. Pen & Fun & Pavilion www.biquge.info

"This power bank is a mobile phone, and charging is a mobile power supply." Wang Cheng explained as he placed the power bank on the table.

"I know that." Fan Jin suddenly spoke, and everyone's eyes suddenly shifted to him.

Wang Cheng looked at Fan Jin with wide eyes, I am almost certain that there is no such thing as a power bank on the market now, and he has not disclosed the power bank project to anyone other than his partner.

Looking at the puzzled eyes of everyone, Fan Jin subconsciously touched his nose and began to explain: "I saw it in a magazine, which said that the process of mobile power supply like this, this thing first appeared at the CES exhibition in 2001, it was a foreign student with several AA batteries and a control circuit put together, that was the initial prototype and concept, but there were no related products on the market." ”

Wang Cheng didn't expect that the mobile power supply appeared as early as 2001, and he didn't know about the existence of the power bank until about 12 years in his previous life; However, think about it, now that smartphones have not yet become popular, most people's mobile phone batteries are removable, and people who travel a lot must have a few spare batteries in their bags.

And by about 12 years, only mobile phones have been popularized in China, and the batteries of many mobile phones have become non-removable.

"But is this a power bank? It's a lot smaller than I thought! Fan Jin curiously picked up the small power bank and said.

"You think it's a battery!" As soon as Zhao Tiezhu said this, everyone began to make up the impression of the mobile power supply in everyone's mind.

It's really a boxy head big battery!

"But what can you charge with such a big deal?" Zhao Fei snatched the power bank in Fan Jin's hand and began to play, young people have never lacked interest in novelties.

"Guess what?" Wang Cheng deliberately bought a pass.

"Toy cars?"

"Radio?"

“psp？”

"Cell phone?"

All kinds of things came out of their mouths, knowing that Shen Tao said the word "mobile phone" suspiciously, Wang Cheng Cai Shuqi gave a thumbs up.

"Feige is right, this is used to charge mobile phones, of course, small appliances such as PSP can also be used, but the main function is to charge mobile phones." Wang Cheng explained.

"How many times can this be charged, and besides, how can I charge it?" Zhao Fei gave Wang Cheng a lot of face and continued to ask.

"This one is 8000 mAh, and it should be able to be fully charged at least two or three times like an iPhone." Wang Cheng did not have accurate data, but could only make a rough estimate.

After all, addition and subtraction are not applicable to power banks.

"Wow, really?" Zhao Fei looked at the power bank in his hand with a surprised expression, he couldn't imagine that such a small thing was worth three spare batteries.

Of course, the iPhone does not have a backup battery, and when there is no power, you can only go home or find an outlet, and then be bound to the radius of the data cable; The emergence of power bank just solves this situation.

There is a saying: Ma Ma no longer has to worry about my phone running out of power and can't find the socket~

"But it should take a lot of time for this power bank to be fully charged." Fan Jin said with some understanding.

"That's right, it takes about five to six hours to fully charge an 8,000 mAh power bank." Wang Cheng is also helpless about this, but this does not affect the practicality of the product.

"It's a bit long!" Zhao Fei nodded and said.

"Actually, it doesn't make much difference, as long as you put it there at night before going to bed to charge, and the next morning it will be full, so you can use it for the day." Wang Cheng explained.

He knew that he had a mobile phone in his previous life and five minutes of charging and two hours of calls, but flash charging doesn't seem to be suitable for power banks, right? Even if it was applicable, he couldn't remember who invented such a technology, whether it was Fudan University or Tsinghua University?

"Hurry up and give me a try, my phone just doesn't move." Zhao Tiezhu immediately brought his mobile phone, did he forget to charge it before going to bed last night, and now there is about 15% of the power left, which is equal to no power for a touchscreen mobile phone.

Wang Cheng did not refuse, and immediately demonstrated how to use the power bank in front of them, and after pressing and holding the switch, four small LED lights lit up.

"This is the existing power of the power bank, the four lights are all on, it means that it is full, if it flashes a few times and goes off, it means that there is no power." Wang Cheng began to explain slowly, wondering if the power bank was attractive to young people like them at the moment.

"Just plug it in."

"It's really charged." Zhao Tiezhu looked at his mobile phone and was happy like a naïve child.

"Wangtou, where did you buy this thing? Is there a larger capacity? I'm going to buy a few more to give to a friend. Shen Tao immediately had the desire to buy, of course, not only for himself but also for his friends.

Because it is difficult to find a working socket when holding a laptop, with such a power bank, they can always use any place as an office space.

"This is not available on the market now, and it should be on the market in a while, and I will not have anyone to give one away in two days." Wang Cheng liked Shen Tao's reaction very much, because of this, Wang Cheng seemed to be throwing money at him.

"Where did you come from, the king?" Zhao Fei shook the power bank in his hand and said.

"I developed it with a company that I partnered with." Wang Cheng didn't hide it, this is also the strength he has, and he can make his employees feel at ease.

"Wow, what's going on in your head, Wang?" Fan Jin exclaimed.

What happened to Wang Cheng, Fan Jin, as the first batch of old employees, was naturally clear, and it turned out that Wang Cheng had no background as he said, and an orphan became what he is now within a few months; In addition to marveling at the still genius, Fan Jin didn't know what else to say.

"Okay, so let's stop talking about it, let's talk about what you think of the future of this kind of thing?" Wang Chengkai asked the opinions of insiders, which can be regarded as a small market research.

After all, all of the people present are post-80s, and now the main force of purchasing power!

"I don't know what the prospects are for it, but I'll definitely buy one, I just don't know the price?" Shen Tao said without hesitation.

(The second one came a little later than usual, asking for support, and the ashes indicate that I have been a little weak recently!) ）
