How to buy mobile phone wireless charger
1. Identification criteria
Wireless charging currently has two major international mainstream industry standards. One is the QI standard of the Wireless Charging Alliance (WPC), and the other is the AirFuelAlliance. These two standards make unified provisions for the performance, technical parameters, compatibility, and safety of wireless charging products, and have strict certification standards.
2, try to choose more than 10W power
With the more mature technology, more and more people pursue charging speed, buy a high-power wireless charger, and the future software system upgrade can also be used. It is recommended that when purchasing wireless charging equipment, try to choose a wireless charger with a power of more than 10W.
3. The conversion efficiency should be high and the charging speed should be fast
Wireless chargers have a conversion efficiency problem, the current mobile phone wireless charger conversion efficiency is more than 60%-80%. Under the same conditions, the higher the efficiency, the faster the charging speed. However, efficiency is not the only factor determining charging speed. Some manufacturers with strong technical strength improve chip performance, optimize program design, and adjust the current output so that the speed of wireless charging can match or even exceed the speed of wired charging.
