Regarding the Qi standard, Qi is a wireless charging technology standard developed by the Wireless Power Consortium (WPC) with the aim of providing a unified standard for wireless charging devices, thus achieving interoperability and interchangeability.
Wireless charging products that comply with the Qi standard can charge each other with other Qi-compliant devices.
Non-standard wireless charging products refer to products that do not comply with the Qi standard. They may use their own proprietary technology or other wireless charging technology standards from their respective factories.
Qi Standard: A wireless charging technology standard developed by the Wireless Power Consortium (WPC). It is mainly applied in fields such as mobile devices and smart homes.
PMA Standard: A wireless charging technology standard developed by the Power Matters Alliance (PMA). It is mainly applied in wireless charging for commercial and public places.
AirFuel Standard: A wireless charging technology standard developed by the AirFuel Alliance, which includes Inductive, Resonant, and RF technologies. It is mainly applied in fields such as mobile devices and smart homes.
CHAdeMO Standard: A fast charging standard for electric vehicles jointly developed by Japanese automakers and power companies. It is mainly used for charging electric vehicles.
Different countries and regions have different technical standards for wireless charging markets. For example, the Chinese market generally adopts the Qi standard, while the US market is more dispersed and mainly uses the Qi and PMA standards. In the European market, the Qi standard is more common.
The PMA wireless charging standard has been merged into another wireless charging standard organization, the AirFuel Alliance. The AirFuel Alliance’s standard includes two wireless charging technologies: Resonant and Inductive. Resonant technology is similar to the PMA wireless charging standard, and is based on electromagnetic induction technology. Inductive technology is a more common wireless charging technology and is the technology used in the Qi wireless charging standard.
Therefore, if you want to purchase a wireless charger that supports the PMA standard, you can look for a wireless charger that supports the AirFuel Alliance standard, where a wireless charger with Resonant technology is a wireless charger that supports the PMA standard.
QC3.0 (Quick Charge 3.0) is a fast charging technology launched by Qualcomm, which can provide faster charging speed than traditional charging methods. QC3.0 fast charging technology is mainly used for charging smartphones, tablets, and other electronic devices, and is a fast, efficient, and safe charging method.
Compared with traditional charging methods, QC3.0 fast charging technology has the following advantages:
Faster charging speed: QC3.0 technology can increase the charging speed up to 4 times faster than traditional charging methods.
Higher charging efficiency: QC3.0 technology can achieve higher charging efficiency and provide more power to the device in a shorter period.
Better compatibility: QC3.0 technology is backward compatible and can be compatible with devices that support QC2.0, QC1.0, and other traditional charging methods.
Safer: QC3.0 technology has multiple built-in protection mechanisms to ensure the safety and stability of charging, preventing problems such as overheating, overcharging, overcurrent, and short circuits.
It should be noted that QC3.0 technology needs to be used together with chargers and devices that support this technology to enjoy its fast charging benefits. If you use chargers or devices that do not support QC3.0 technology for charging, you cannot enjoy the fast charging effect of QC3.0.
