I Have A Super USB Drive

"Not enough energy."

Looking at the latest pop-up window, Chen Chen showed a thoughtful look.

Obviously, the most difficult situation arises.

Because of the realization of NZT-48, the USB flash drive has run out of energy and cannot be used for other things.

However, Chen Chen also got some good news.

Since the word "insufficient energy" can appear, it can be reversed that the U disk can be charged.

As long as things are not at their worst, there is still a chance of recovery.

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

Chen Chen stared straight at the old and dim USB flash drive in front of him, and suddenly his heart moved.

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 conditioners are often used, so the dormitory of Shangdu Jiaotong University does not restrict high-power electrical appliances.

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

At this time, the electricity meter shows that there is still 52.65 kWh of available electricity in the electricity card of dormitory 404.

power?

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

That is to say, the rated power of the notebook is about 150W, and it consumes 0.15 kWh in one 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 per hour is about 0.0025 degrees.

Thinking of this, Chen Chen frowned, pulled out the USB flash drive, and looked at the wiring board on the table.

This wiring board was bought by the four people in the dormitory at the beginning of the school year.

And for convenience, I bought a terminal board with a dedicated USB jack.

Chen Chen looked at the wiring board. The power of the USB socket marked on it was 5V and 4A. That is to say, the maximum power of the USB interface was 20W, and the power consumption was 0.02 degrees per hour.

Thinking of this, Chen Chen inserted the USB flash drive into the USB jack of the power strip.

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

Chen Chen pondered, there is only one power-consuming device in the dormitory, as long as the computer is turned off, if the meter is still running after an hour, it means that the USB flash drive can really absorb power.

The reason why it was not directly plugged into the USB port of the computer was because the USB power of the computer was too low, and the meter could only reflect the last two digits of the decimal point at most.

Looking at the time, Chen Chen took out his phone and set an alarm for an hour.

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

...

An hour passed in a hurry.

When the alarm on the mobile phone rang, Chen Chen just turned the last page, but at this time Chen Chen was not satisfied.

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

It seems that it is necessary to go to the library after this work is done.

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

Available electricity: 52.63 kWh.

Consumed 0.02 kWh in one hour, sure enough!

Chen Chen's eyes lit up. At this time, he was sure that the USB flash drive could really charge himself with electricity.

This discovery can be described as exciting, no worse than the significance of NZT-48.

Just when Chen Chen was excited,

Suddenly his ears moved slightly, and he quickly pulled out the USB flash drive and stuffed it into his pocket.

A footstep sounded from far to near, Chen Chen looked towards the door, and the dormitory door was kicked open with a bang.

Li Bo walked in with the steps of social shaking.

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

Seeing Chen Chen staying in the dormitory, Li Bo immediately shouted, "Old Deng asked you specifically for the name!"

"I've asked the counselor on leave."

Chen Chen didn't turn his head and said, "Bozi, we shouldn't be together in the future."

"Why?"

"Walk with you, I'm afraid I'll be beaten when I go out."

Chen Chen packed up his books, and seeing that it was not yet five o'clock in the afternoon, he got up and walked outside the dormitory.

"Where are you going? Let's go out to AA for dinner together later?"

"No money, farewell."

Chen Chen left without looking back.

At this time, his state was obviously different from before, and even Chen Chen could sense this.

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

No fear, no shyness, no shyness...

Yes, just unhurried self-confidence.

This kind of aura was difficult to hide, so Chen Chen stayed away from acquaintances as much as possible, so as not to be seen for any flaws.

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

The life of the poor is so simple and unpretentious.

and boring.

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

If you want to reach the pinnacle of life, although NZT-48 is enough, but your heart is not enough to swallow an elephant, how can you be satisfied with this?

My next step, of course, is to find ways to recharge the USB flash drive and try to squeeze out the maximum value of the USB flash drive.

You know, the power of the USB interface 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, which is definitely an astronomical figure.

Therefore, Chen Chen needs a lot of money.

With money, whether it is to buy a factory in an industrial park or build a power plant by yourself, you can deal with it calmly.

Only in this way can Chen Chen supply enough power to the USB flash drive without being noticed by the outside world.

So, the source of all this is money.

And now, there is only one way for Chen Chen to obtain 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.

In 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. There are piles of books in several convenient and quiet prime locations. If someone hadn't cleaned them up at night, I'm afraid some books would be piled up with dust.

Chen Chen came to the foreign language reading room, took a few glances, picked out a copy of "Modern College English (Second Edition)", and found a decent place to sit down.

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

Until just now, Chen Chen suddenly understood.

Although I don't want to admit it, North America is the real core area of ​​the federation. Whether it's economy or technology, it's the real core.

And those really advanced and authoritative academic papers 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.

But it is such a meaning, which is often missed by a thousand miles, creating many difficulties for the scientific research of Zhongzhou.

Therefore, if Chen Chen wants to enter the field of scientific research, proficient in English is the most basic stepping stone.

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

Not foreigner, not elbows out, just to keep up with them.

That's all.
