2c1a + 65W + three hole output, support three devices fast charging at the same time? First experience of Gan black Technology

Gallium nitride is a new semiconductor material. It is said that it can reduce the volume, lower the temperature and improve the charging efficiency. It is the most popular charging “black technology” recently. In my opinion, Gan fast charging belongs to consumption upgrading, and even more to rigid demand. < / P > < p > compared with the charging head of mobile phone and tablet, the cumbersome power adapter of notebook computer is really behind. Although many new laptops use the C port, in order to control the cost, the power adapter has not been followed up and needs to be purchased by consumers themselves. < / P > < p > recently, the newly purchased Lenovo Xiaoxin Pro 13 is still using the old power adapter, which stimulates my demand for 65W PD fast charging head in disguise. Finally, after repeated selection, gritted teeth and ordered the second generation Gan charging head of Beisi at 129 yuan. Although it’s not the lowest price in history, it’s a normal price. < / P > < p > to be honest, I have no contact with Beisi brand, so I did a lot of homework before I bought it. Compared with the Gan fast charging of Xiaomi, Huawei, Nubia and Xiaomi, Beisi still has certain advantages in the same price. < / P > < p > first of all, in the price of more than 100 yuan, the second generation of Beisi is one of the few 65W fast charging head that supports 2c1a three holes. Other products either have only one C port or are third rate brands whose names have never been seen before. In order to seek stability, they still buy Beisi. < / P > < p > here, I still want to criticize some manufacturers for having only one c-hole after Gan fast charging. What’s the point? We consumers buy Gan fast charging head, is not to facilitate multi device charging, once and for all? < / P > < p > secondly, the old users all know that the first generation Bess Gan fast charging has the problems of overheating temperature and poor handshake compatibility of fast charging protocol. Bess Gan fast charging is the second generation. Compared with the first generation, it optimizes the temperature and fast charging compatibility, and has a real reputation. < / P > < p > there is a trial and error and optimization process for new technologies. After all, I bought them for my own use, and I don’t want to be the first batch of mice. The above is my psychological activities before buying. I believe that every consumer who is willing to spend 100 yuan to buy fast charging head should have thought about these problems. < / P > < p > the fast charging of Bess II GaN has arrived. In fact, there is nothing to say about unpacking, that is, simple packaging. The volume of the 65W fast charging head is similar to that of the 33W fast charging head standard for red rice, but it is a little more slender. It can be seen that gallium nitride technology can indeed reduce the volume. < / P > < p > 2c1a three hole position, double port blind plug can output 65W power, of which the a port is only 24W at most. In the manual, Bess notes the charging protocol of each charging port. You can have a look at it. The supported protocols are quite complete. My devices are iPhone 11, Hongmi K30 supreme edition and Lenovo Xiaoxin Pro 13, all of which support PD protocol. < / P > < p > the main suspense is Lenovo Xiaoxin Pro 13, the original adapter is 65W, before most third-party PD fast charging can only charge with 45W power, playing games will also power down. For example, Beisi generation GaN has this problem. Charging Lenovo Xiaoxin Pro 13 can only output 45W power. < / P > < p > the most important reason for Beisi’s second generation Gan is that it is perfectly compatible with Lenovo’s 65W charging protocol. During the actual baking process, the charging head can output 65W single port full power. Don’t worry about power down. < / P > < p > continued the simple test. The measured charging data is that charging the premium version of Hongmi K30 from 4% to 67% in 30 minutes, charging 63%, which is a little slower than the original 33W. Charging the iPhone 11 from 28% to 85% in 41 minutes, charging 57%. < / P > < p > I’m neglecting here, but excluding the trickle charge after 80%, we can judge that it is 18W full power. After all, it only took one day, and there is no professional equipment, so we can only test it here. Let’s make a reference. < / P > < p > an interesting point is that bess-2 Gan will also turn on the blue light during charging, indicating that it is “charging”. Emmm, I have to say, this design is quite safe. < / P > < p > the above is my personal shopping experience, and I am very satisfied with it up to now. I also have a certain understanding of Gan as a black technology. If nothing unexpected happens, in the future, the fast charging of porous Gan will be popularized rapidly, and the era of “fast charging head taking the lead in the world” will soon come. The experience improvement brought by gallium nitride is very intuitive. I hope manufacturers can follow up quickly.
