Flexible and convenient: non-contact, one-to-many charging, compared with the general charger, it reduces the trouble of plugging and unplugging, and also avoids the phenomenon of inappropriate interface and poor contact. Although poor contact caused by wired charging is rare, wireless charging basically has no such hidden danger.
Universality: having universal standards is one of the advantages of wireless charging. There are many wired charging interfaces, including Micro USB of Android, Type-C, and Lightning interface of Apple. Different phones need different interfaces. Wireless charger is not so troublesome, it can be used if it supports wireless charging. At present, the standard is mainly QI wireless charging.
Of course, wireless chargers also have disadvantages. At present, the charging speed is still faster than wired charging, and wired charging has been able to achieve such high-power charging as 30W and 40W. Wireless, mainly charging at 7.5W and 10W, which is relatively slow. The cost is high, the maintenance consumption is high, and there will be potential safety hazards if it fails to meet the standards.

There are three standards for wireless charging: uniform standard, standard and standard.
Qi standard: Qi standard is a wireless charging standard introduced by the Wireless Power Alliance (WPC, established in 2008), and it is the first standardization organization in the world to promote wireless charging technology. It adopts the most mainstream electromagnetic induction technology at present, and has two characteristics: compatibility and universality. As long as it is a product with Qi logo, it can be charged with Qi wireless charger. 2065438+In February 2007, Apple joined WPC.
PMA standard: PMA Alliance is committed to creating wireless power supply standards for mobile phones and electronic devices that meet the standards of IEEE Association, and is in a leading position in the field of wireless charging. PMA also uses the principle of electromagnetic induction to realize wireless charging. At present, there is already AT&; T, Google and Starbucks joined the PMA alliance.
A4WP: Alliance for Wireless Power Standard, initiated on 20 12, aims to establish technical standards and industry dialogue mechanism for wireless charging equipment for electronic products, including portable electronic products and electric vehicles. A4WP adopts electromagnetic vibration principle to realize wireless charging.
