Fast charging is related to both the phone charger and the data cable.
Both chargers and data cables need to buy chargers and Type-c data cables that support fast charging 3.0.
The current of fast charging is usually 3A~6A, and such a large current for the charger circuit and data cable need to meet the standard in order to support such a large current transfer.
According to different functions, Type-c data cables can be divided into:
Type-C charging cable: only support charging function;
Type-C data cable: supports charging + data transfer function;
Full-function Type-C data cable: support fast charging + data transmission + video transmission function;
According to the function selection, we also need to pay attention to the supported charging power/protocol, interface transmission standards, etc..
PD fast charging data cable: (current size classification) according to the current size can be divided into: 2A, 3A, 5A, 6A and so on. The higher the current, the more expensive, high current version can be downward compatible with small current version of the device. 3A fast charging, the working power has 18W/27W, 33W. 5A fast charge, the working power has 18W/27W, 33W.
5A fast charging, working power has 22.5W/40W, 55W. 6A fast charging, working power has 30W/65W, 120W. USB-C Gen2 version of the full-featured dual-port Type-c cable not only supports PD100W fast charging, but also supports 10gb/s data transmission, which can realize 4K HD casting.
Choose USB-IF certified transmission cable is more secure “USB-IF” is the abbreviation of the USB Developers Forum, through the “USB-IF” organization certified cable, the packaging will indicate “SuperSpeed USB” or “SuperSpeed + USB” logo, relative to not certified cable is more secure, but the price is also more expensive USB Type-C There are many types of USB Type-C, so the USB-IF has set a hardware threshold: support for 5A high current, support for USB 3.0 or higher transfer speeds, and support for video output functions, all of which require the support of the E-Marker chip.
