What is a PD charger

The PD charger is actually a charger using the PD fast charging protocol. 140w PD charger is one of the most representative ones.The PD charging protocol is a power transmission protocol announced by the USB-IF organization, which is different from other fast charging protocols on the market because the main body of the protocol is different. For example, the QC protocol is a Qualcomm protocol and is formulated by chip manufacturers. Huawei's SCP, OPPO's VOOC, Samsung's AFC and other protocols are formulated by mobile phone manufacturers. Combining various fast charging protocols, USB PD has a wider range of application scenarios, because there is no need to consider the chip and brand, after all, everyone is charged through USB.

What is a GAN

Gallium Nitride (also known as GaN) is a material increasingly used in charger semiconductors, used to make LEDs since the 1990s, and is a common material for satellite solar cell arrays. The biggest advantage of using GaN for chargers is that it generates less heat. Less heat generation means components can be placed closer together, so chargers can be made smaller than ever, while retaining all charging functions and meeting safety standards.

GaN will replace silicon

Silicon has been the material of choice for transistors since the 1980s. Silicon conducts electricity better than previously used materials such as vacuum tubes, which can reduce costs due to lower production costs. Technological advancements over the past few decades have brought about the high performance we are now used to. Progress has its limits, and silicon transistors may be nearing the pinnacle of development. Due to the properties of silicon material itself in terms of heat and power transmission, components cannot be made any smaller.
GaN, on the other hand, is a crystalline material that conducts higher voltages. Current flows faster through components made of GaN than silicon, and as a result, the processing speed becomes faster. GaN is more efficient and therefore generates less heat.
