· Why is the laptop power adapter not integrated into the laptop body?

Every time I need to carry a laptop on a business trip, I wonder why the laptop power adapter cannot be made built-in, and it's inconvenient to carry a guy like a big brick. I believe there must be more than one person who thinks this way, so why is this? The power adapter manufacturer believes that the main reason is still technical.With the current level of technology, it is very difficult to meet the requirements of integrating power into the laptop body in terms of heat generation, EMI, size, and other aspects. Next, we can briefly analyze.Nowadays, the majority of power adapters for laptops are switch mode power supplies. For switch mode power supplies, they are generally composed of the following key components: AC mains ->input filtering ->rectification ->switch ->transformer ->filtering ->DC output input filtering. In this regard, XY capacitors and common mode inductors are generally used, mainly to filter out interference signals from the mains power supply...

· Is there a relationship between the explosion during phone charging and the charger?

The fundamental reason for the explosion of a mobile phone is a short circuit in the battery. The vast majority of phone explosions are caused by battery explosions. During charging. The internal resistance of the battery is small, and the current generated instantly after connecting the power is too high, causing a short circuit in the power supply and causing the battery temperature to overheat and explode. So is it related to the charger? Many people have always believed that the explosion of mobile phones is closely related to the use of non original third-party chargers, but the fact is that only when you use cheap and uncertified chargers will there be significant safety hazards. And regular chargers are generally safe.Why? The reason for the explosion of a mobile phone is that the temperature is too high for a short period of time, and the lithium battery burns, leading to the explosion of the phone. A regular 5V charger with low power cannot release too much energy during char...

· Can the eye protection mode of a mobile phone really protect the eyes?

Once staying up late to play computer games, now playing with mobile phones without sleeping, mobile phones are gradually replacing computers as the most commonly used entertainment and internet tool. Due to their portability, people can play anytime, anywhere and in various positions. I had fun playing, but many people's eyes were also blurred. Especially for children and adolescents who are growing and developing, excessive use of mobile phones can easily lead to myopia. Is there a good preventive measure? Kinri Energy suggests that in addition to scheduling your time properly, you can also activate your phone's eye protection mode while using it.What exactly harms the eyes while using a mobile phone? In fact, the culprit is the "blue light" emitted by the screen. The light emitted by the screen is mainly short wave high-energy blue light at the end of the visible spectrum, and the wavelength of high-energy blue light is between 380-450nm. Research has shown that human cells lose th...

· What are the advantages of the Type-C interface?

Since Apple first adopted the Type-C interface on Macbooks, more and more laptops have been equipped with the Type-C interface. However, many people do not know the advantages of this interface. Today, Type-C charger manufacturers will briefly introduce it to you.1. Support "forward and reverse insertion" to improve office efficiency. In the past, there were directional issues with USB interfaces, often resulting in incorrect insertion, which not only affected the user experience but also wasted time. The Type-C interface has the same front and back, supporting the "front and back insertion" function that can be inserted from both sides, solving the problem of "USB always not inserted correctly", allowing users to avoid incorrect insertion during use, and can withstand 10000 repeated insertions and withdrawals.2. Faster transfer rate: In the past, transferring slightly larger files would take a longer time, but the emergence of Type-C has accelerated everything. Type-C can copy large...

· The principle of mobile phone charging

How to make boring knowledge interesting and abstract things vivid? Today, Kinri will use a simple model of "draining water" to help everyone understand the relevant knowledge about mobile phone charging.Water tank: used to indicate our power grid, our vast power grid, you can imagine it as a bucket of water.Valve: You can imagine it as a charger that controls the amount of water flowing into the cup by repeatedly switching on and off. If it weren't for this valve, you could imagine the consequences. In foreign countries, it is customary to call a charger an adapter, which means it has an adaptive function.Water cup: It can be imagined as our phone battery or tablet battery. Water is electricity, transmitted through water pipes.A mobile phone charger is actually a flyback type switching power supply, which generally has the following concepts: output voltage, output current, ripple, CV (constant voltage charging), CC (constant current charging). We can understand the process of chargi...
