Three development status of notebook power adapter!

May 27, 2020
         Since the birth of the laptop, it has been more than thirty years. As an important productivity tool to promote human development, the laptop has now become an indispensable role around us, and with the continuous development of so many years, , Security, stability and other aspects are not the same, but at the same time you can also find that its supporting hardware notebook power adapter has not changed much! Without a unified standard, there will be such a complicated classification of notebook power adapters. At present, the most difficult problem for notebook power adapters is that there is no unified standard, and various power adapters grow wildly, so the notebook power we have seen They are all varied and difficult to classify. They can be classified by brand, such as several well-known international manufacturers (in alphabetical order): Acer (Acer), APPLE (Apple), ASUS (ASUS), DELL (Dell), HP (HP), LENOVO (Lenovo) , TOSHIBA (Toshiba). According to the use, it is divided into AC (for example, household and office use AC is called AC), DC (for example, in cars and airplanes, DC is called DC). According to the output voltage and current (on the label on the back of the charger, generally written after OUTPUT, how much V, how much A is written), which includes 12V series, 15V series, 16V series, 18.5V series, 19V series, 19.5V Series, 20V series, 24V series, etc., this is just the voltage, the current of the same series can be very different ~ In addition, even if the voltage and current are the same, the chance of their interface size being the same is also very small, just from the shape of the interface , Long, flat, square, round, however, the circle is also divided into big and small circles ... so it is really difficult to make a wood?

     Most of the appearance has been using the traditional shape of the brick-shaped "power adapter is very common in game books, now go online to search, as long as it is a notebook power supply related products, 80% or 90% are traditional notebook power adapters, traditional notebooks First, the power supply is bulky and not portable, and the second is weight issues. If it is used as a brick in some unexpected accidents, it is not excessive! However, some power supply manufacturers have begun to develop like small-sized notebook power adapters. Technology has produced a very small 65W ultra-small notebook power adapter, and it is a model that matches multiple brands.

    Wire "disaster"

      The cable problem must be a headache for computer users. Many people have experienced the feeling of mixing the mouse cable, keyboard cable, power cable, and audio. This situation is for most people. It is almost a disaster, so later, the mouse and keyboard have realized wireless connection, so can the notebook power adapter realize wireless charging? Not to mention that it is really possible, Dell has recently exhibited a notebook with a wireless charging design, which looks very similar to the design idea of wireless charging for mobile phones. But at present, I personally think that it can be realized in a short time if it is only used for office work, but it will be very inconvenient if traveling or the like, because this wireless charge is large and not easy to carry. However, this product is currently only in the development stage, I believe there will be a substantial breakthrough in the future.
