At the new product launch held at 1:00 a.m. on September 16, Apple released two new smart watches and two iPads. Among them, the new iPad 8 realized stronger performance through apple A12 bionic chip. At the same time, the iPad 8 also supports USB PD fast charging, and is equipped with 20W PD fast charging charger which has been exposed many times before. At present, the charging head network has obtained the iPad 8 original 20W PD fast charging charger. Here is to share the hands-on experience of this product. < / P > < p > Apple 20W PD fast charging continues the style of Apple 18W PD fast charging. It adopts fixed pins, the main shell is white baking varnish, and the input and output end faces are light gray. This is the version of the Bank of China, with product parameter information printed on the side of the pin. < / P > < p > according to the parameter information of the pin side, the charger is manufactured by selcom Technology (Shenzhen) Co., Ltd. The charger product model is a2244, which is consistent with the previous disclosure; it supports 100-24 V 50 / 60 Hz 0.5 a input, and the output is 5V 3a, 9V 2.22a. Serial number (SN): f1603430jjmpmg9au. < p > < p > compared with 18W PD fast charging, the appearance size, weight and hand feel of Apple 20W PD fast charging are basically the same. The difference is that 20W PD fast charging clearly indicates the charger power on the pin side. < / P > < p > to identify the authenticity of Apple chargers, in addition to looking at the appearance, we can also use chargerlab power-z mf001 to read the charger serial number. The test results show that the serial number of the charger is f1603430jjmpmg9au, which is consistent with the marking on the case. < / P > < p > from the charging test of Apple 20W PD fast charging to Apple devices, all PD devices including MacBook are supported for fast charging, and apple 2.4a full speed charging can be realized for products that do not support PD fast charging. < / P > < p > the charging power of Apple 20W PD fast charging device is made into a column chart, which is convenient for comparison and analysis. In the USB PD fast charging mode, the power of other products can reach more than 18W, and the maximum power can reach 19.4w except for the small charging power of iPhone se2. < p > < p > the appearance of Apple 20W PD quick charging is almost unchanged compared with the old 18W PD fast charging model, which should be from the same set of shell mold. Just like this, Apple’s 20W PD fast charging has not only slightly updated the output parameters, but also marked “20W” on the shell, which makes it easier for ordinary users to distinguish from 18W PD fast charging. < / P > < p > it is worth mentioning that the 20W PD quick charging of apple is manufactured by selcom, which indicates that Celcom has entered the apple fast charging supply chain.
