I Have A Super USB Drive

"Not enough energy."

Looking at the latest pop-up window, Chen Chen looked thoughtful.

Obviously, the most difficult situation has emerged.

Because the USB flash drive has realized NZT-48, it has run out of energy and cannot show other things again.

However, Chen Chen also got good news.

Since the words "insufficient energy" can appear, it can be reversed to explain that the USB flash drive can be charged.

As long as things have not reached the worst point, there is still a chance to recover.

But, this U disk, what kind of energy does he need?

Chen Chen stared straight at the old and dim USB flash drive before his eyes, and suddenly moved in his heart.

He walked to the door of the dormitory and looked up.

An ic card meter is mounted on the wall.

Because it is located on the coast, air conditioning is often needed, so the dormitory of Shangdu Jiaotong University does not restrict high-power electrical appliances.

However, each dormitory has an electric switch, and the total power is limited to around 10A.

At this time, the electricity meter showed that there was 52.65 kWh of available electricity in the electricity card of the 404 dormitory.

Battery?

Chen Chen turned around and found the notebook computer manual, and found that the output voltage of his computer was 19V and the output current was 7.8A.

In other words, the notebook has a rated power of about 150W and consumes 0.15 kWh of electricity per hour.

In the USB protocol specification, the USB power supply voltage is about 5V and the maximum power supply current is 500mA. That is to say, the maximum output power of a single USB port is 2.5W, and the energy consumption is about 0.0025 degrees per hour.

Thinking of this, Chen Chen frowned, pulled out the U disk directly, and looked at the wiring board on the table.

This patch panel was purchased by the four people in the dormitory at the beginning of school. It was put on the table and was enough for the life of the four people.

And for convenience, I bought a patch panel with a USB dedicated jack.

Chen Chen looked at the wiring board. The power of the USB jack indicated on it was 5V and 4A. That is to say, the maximum power of the USB interface is 20W, which consumes 0.02 kWh per hour.

Thinking of this, Chen Chen inserted the U disk into the USB jack of the patch panel.

"If my guess is correct, U disk can use electricity to supplement energy, then it should be reflected on the meter."

Chen Chen thought about it. Now there is only a computer in the dormitory that consumes electricity. As long as the computer is turned off, if the meter is still running after an hour, it means that the U disk can really absorb electricity.

The reason for not plugging directly into the USB port of the computer before is because the power of the computer USB is too low, and the meter can only reflect the last two decimal places at most. It is plugged into the computer USB, even if there is energy consumption, it is not visible at all.

After checking the time, Chen Chen took out his phone and set an alarm clock for another hour.

Then he turned off the computer, opened a book of "Modern Molecular Biology" and read it silently.

...

An hour passed in a hurry.

When the mobile phone alarm went off, Chen Chen happened to turn over the last page, but Chen Chen was not satisfied at this time.

The book "Modern Molecular Biology" is not bad for teaching, but for Chen Chen it is a bit crude and general, and cannot satisfy his learning depth.

It seems that it is necessary to go to the library after this matter is over.

Chen Chen made up his mind, then walked to the meter and looked at the numbers on it.

Available power: 52.63 kWh.

It consumes 0.02 kWh in one hour, sure enough!

Chen Chen's eyes lit up, and he was sure at this moment that the U disk could really charge himself with electricity.

This discovery can be described as exciting, and it is no less meaningful than the realization of NZT-48.

Just when Chen Chen was so excited,

There was a sound of footsteps from far to near, and Chen Chen looked at the door, and suddenly the door of the dormitory was kicked open with a "clang".

Li Bo walked in at the pace of the society.

"Chen Chen, you didn't even go to class this afternoon!"

Seeing Chen Chen staying in the dormitory, Li Bo immediately yelled, "Lao Deng specifically asked you about the name!"

"I asked the counselor for leave."

Chen Chen didn't look back, "Bozai, let's not walk together in the future."

"Why?"

"Walking with you, I am afraid of being beaten when I go out."

Chen Chen cleaned up his books and saw that it hadn't been five o'clock in the afternoon, so he got up and walked outside the dormitory.

"Where are you going, go to AA dinner together later?"

"No money, goodbye."

Chen Chen left without looking back.

His state at this time was obviously different from before, which even Chen Chen himself could perceive.

If he used to be just a low-key and dull young man, then he is now a successful person full of confidence and calmness.

No fear, no shyness, no shyness...

Yes, it's just self-confidence that is leisurely.

This kind of aura is difficult to conceal, so Chen Chen stayed away from acquaintances as much as possible so as not to be spotted any flaws.

When he came to the canteen, Chen Chen bought four steamed buns with two yuan, ate two, and then put the remaining two in a plastic bag for later use when he was panicking at night.

The life of the poor is so unpretentious.

And boring.

Chen Chen walked to the library while thinking about the next steps.

If you want to reach the pinnacle of your life, even though NZT-48 is enough, but you don’t have enough hearts, how can you be satisfied with it?

My next step, of course, is to find ways to charge the U disk, and try to squeeze the maximum value of the U disk.

You know, the USB port power of the cable board is definitely not enough.

Although I don't know how much energy the U disk needs to meet the realization conditions, I can think of it with my toes. That is definitely an astronomical figure.

Therefore, Chen Chen needs a lot of money.

After having money, whether it is going to an industrial park to buy a factory or building a power plant by yourself, you can deal with it calmly.

Only in this way can Chen Chen be able to supply enough power to the U disk without being noticed by the outside world.

So, the source of all this is money.

Now, Chen Chen has only one way to get money, and that is to rely on the power of NZT.

Thinking of this, Chen Chen no longer hesitated and stepped into the library building with both feet.

Looking at the crowd in the library, Chen Chen sighed silently.

For the next period of time, I will be here permanently.

There is never a shortage of'books in the absence of people' in the library. Several convenient and secluded golden locations are occupied by piles of books. If it is not cleared at night, some books may pile up dust.

Chen Chen came to the foreign language reading room, scanned a few times, picked a copy of Modern College English (Second Edition), and sat down in a decent place.

Chen Chen once also wondered when he was in junior high and high school, why did Tangtang Zhongzhou take North American languages ​​as a compulsory course and still occupy such a large proportion?

Until just now, Chen Chen suddenly understood.

Although I do not want to admit it, North America is the true core area of ​​the Federation, whether it is economy or technology, it is the true core.

And those academic papers that are truly advanced and authoritative are mostly written in English.

Some academic professional vocabulary is difficult to explain in Chinese, and even if it is translated, it is not so meaningful.

And it is such a meaning, often the slightest difference is a thousand miles away, creating many difficulties for Zhongzhou's scientific research.

Therefore, if Chen Chen wants to step into the field of scientific research, then proficiency in English is the most basic stepping stone.

This is the good intentions of the older generation in the education industry in Zhongzhou.

It's not to fawn on foreigners, it's not to turn the elbow away, just to keep up with them.

That's it.
