I Have A Super USB Drive

　　 "Insufficient 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 indicate that the U disk can be charged.

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

　　Just, what kind of energy does this U disk 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 embedded on the wall.

　　Because it is located along 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 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 per hour is about 0.0025 degrees.

　　 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 is placed on the table and it is enough for the life of the four people.

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

　　 Chen Chen looked at the wiring board. The USB jack power indicated on it is 5V, 4A, that is, 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, the U disk can use electricity to supplement energy, then it should be reflected on the meter."

　　 Chen Chen thought, 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 why I didn’t directly plug into the computer’s USB interface before was because the computer’s USB power was too low.

　　 Checked the time, Chen Chen took out his phone and set an alarm clock for one 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 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 electric meter and looked at the numbers on it.

　　Available power: 52.63 kWh.

　　 0.02 kWh was consumed 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 excited, his ears moved slightly, and he quickly pulled out the U disk and stuffed it into his pocket.

　　 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 "clam".

　　 Li Bo walked in at the pace of 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 asked you specifically for the roll call!"

　　 "I asked the counselor for leave."

　　 Chen Chen didn't turn back, "Bo Tsai, let's not go together anymore."

　　 "Why?"

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

　　 Chen Chen packed 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, I'll go out to AA dinner together?"

　　 "No money, goodbye."

　　 Chen Chen left without looking back.

　　 At this time, his state was obviously different from before, which even Chen Chen 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 cafeteria, Chen Chen bought four buns for two yuan, ate two, and then put the remaining two in a plastic bag, waiting for the night when he was hungry.

　　 The life of the poor is so simple and unpretentious.

　　 and boring.

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

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

　　 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 must know that 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 I have money, I can deal with it calmly whether I go to an industrial park to buy a factory or build a power plant myself.

　　Only in this way, Chen Chen can supply enough power to the U disk without being noticed by the outside world. UU reading www.uukanshu.com

　　 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.

　　 In the next period of time, I will be resident here.

　　 There is never a shortage of ‘books in no one’ 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 out a copy of Modern College English (Second Edition), and sat down in a decent place.

　　 Chen Chen once wondered when he was in junior high and high school, why did Tangtang Zhongzhou take North American language 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, even if it is translated, it lacks a level of meaning.

　　 is such a meaning, often the smallest 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 China.

　　 is not to be fond of foreigners, not to turn the elbow out, just to keep up with their pace.

　　 That's it.
