Guide for comparison and purchase of Gan charger in 2020, recommended by Gan charger / PD charger / Notebook Charger
Gallium nitride (GAN）
GaN, a new type of semiconductor material, has the advantages of high efficiency, low heating, large power but small volume, etc. due to its excellent characteristics, portability and electric energy conversion efficiency.
The three characteristics of gallium nitride are summarized: high switching frequency, large band gap width and lower conduction resistance.
Switching frequency refers to the number of times that the thyristor, thyristor and silicon controlled electronic components can be fully turned on and off per second. High switching frequency can reduce the volume of transformer and capacitance, and help reduce the volume and weight of the charging head.
It is the charger device that uses gallium nitride, and makes the charger smaller.
PPS integrates two charging modes: high voltage, low current and low voltage and high current. Pd3.0 PPS has the voltage precision of 20mV, which is ten times higher than that of high pass qc3.0 standard.
However, the latest PPS is not compatible with the power receiving equipment of pd2.0. It may cause bugs in the devices that support PPS charging head to charge PD 2.0, and it can not be charged quickly
matters needing attention
When multiple interfaces work at the same time, the power of each interface will change, and the full power of single port cannot be reached
For chargers with multiple type-C or type-A ports, the charging power of the same two types-c or type-A may be different
The highest temperature standard for national chargers is not higher than 95 degrees Celsius
