GaN Fast Charge, PD Fast Charge, Ordinary Fast Charge, What’s the Difference?
What is GaN gallium nitride?
Gallium nitride is a kind of material, which is a new semiconductor material for the development of micro-electronic devices and optoelectronic devices. It is often used in high-power and high-speed optoelectronic devices and widely used in aviation and other high-tech fields. It has many advantages, such as large band gap width, high thermal conductivity, high temperature resistance, etc., and is known as the third generation semiconductor material.
Gallium nitride chargers are smaller, lighter, more efficient, and have better heat control. On the other hand, they cost more to develop, so they are more expensive than ordinary chargers.
What is PD Quick Charge?
The common/often said PD fast charging appliance generally refers to the charger supporting USB PD protocol. USB PD protocol is a fast charging specification formulated by USB-IF organization, which is one of the mainstream fast charging protocols and one of the most widely compatible fast charging protocols at present.
Support USB PD protocol charger interface is generally USB-C port, but there are A few magic changes of the charger USB-A port also support USB PD protocol, such as Xiaomi’s 55 W charger.class 2 power supply 120vac 60hz
Other common quick charging protocols:
Xiaomi mobile phone: use QC, PD and private quick charge protocol
Huawei mobile phones use FCP and SCP private quick charge protocols
OPPO phones: Use VOOC/Super VOOC private Quick charge protocol
VIVO mobile phone: Using FlashCharge/Super FlashCharge private quick Charge protocol
Samsung phones: PD, QC, AFC and other protocols are used
egular quick charge?
This kind of do not consider it, even support what fast charge is not marked, it is probably not a big brand, product quality is not guaranteed.
Charger recommendation
Support QC, FCP, AFC, PD, PPS and other protocols, the volume is relatively small at the same power.
Only need to change a small plug-in can be used around the country, reputation and quality are good, support protocols are also very rich, suitable for most of the mainstream equipment.
