Relationship between fast charging connector and charging head

With the rapid development of mobile phones, it has become an indispensable part of people&＃39;s lives. In contrast, the development of lithium batteries is not so rapid. Most smart phones have to face the dilemma of "one charge a day" or even "more charges a day". The battery life of mobile phones has always been a concern. From the beginning of "charging for 5 minutes and talking for 2 hours" to now, major manufacturers have introduced fast charging equipment. However, many machine friends may have a question, is the realization of fast charging of mobile phones the credit of the charging head or the credit of the fast charging connector?

The charging head is the protagonist in the fast charging system, and the output power of the charging head of the fast charging connector is the most direct factor affecting the charging speed. If the power of the charging head is not enough, it is impossible to achieve fast charging. Nowadays, many brands of mobile phones support high-power fast charging, but the standard charging head is still low-power. Is it impossible to realize fast charging? No, just buy a fast charging head!

Not all mobile phones can achieve fast charging by replacing a high-power charging head. For example, Apple&＃39;s PD fast charging needs to purchase a PD charger with a power of 18W or more and a Type-C to Lightning fast charging connector. It is worth noting that not all models of Apple support PD fast charging, and it needs Apple 8 and above models to support it. Therefore, when the machine friends buy, they should open their eyes and see clearly!

The fast charging connector is also very important. The fast charging connector mainly connects the mobile phone with the charging head and is responsible for the transmission of current. Compared with ordinary fast charging connectors, what is the particularity of fast charging connectors that support fast charging? Take the Android phone as an example, which is more intuitive. The ordinary charging cable of Android phone contains three wires working, two are power wires and the other one is ground wire. The fast charging line of Android is basically five lines working. In addition to the original three lines, two power lines have been added.

In the charging line, these two fast charging connectors play a very important role, which is responsible for the communication between the charging head and the mobile phone power management chip. Specifically, it is to negotiate the charging power. For example, a mobile phone supports 40W fast charging, and the power output of the charging head supports 5V/2A, 9V/2A and 10V/4A respectively. At this time, the two fast charging connectors in the fast charging line will communicate when charging, and choose the most appropriate power to charge the mobile phone to achieve the effect of fast charging.

The length of the fast charging connector also has a certain influence on the charging speed. The shorter the fast charging connector, the faster the charging speed will be. Therefore, only by choosing the right charging head and fast charging connector can we achieve the effect of fast charging, and the two are complementary. Of course, it is more important that your mobile phone supports the fast charging protocol. Otherwise, even if you buy a fast charging head and a fast charging connector, you can only use it as a normal charging!
