A: The current wireless charging 30w and wireless charging 20w time is the same, because now the mobile phone wireless charging supports 20w. However, the charging ratio of wireless charging 30w is 4:1, while the charging ratio of wireless charging 20w is 2:1. From the perspective of design efficiency, the efficiency of wireless charging 30w is higher, that is, people are more willing to choose 30w wireless charging equipment in the future.
Different brands have different parameters. Xiaomi 30W wireless flash charge adopts 4:1 direct charge architecture and adopts two-stage charge pump step-down, which improves the charging efficiency compared with the 2:1 direct charge architecture of 20W wireless charging and reduces the heat during charging.
However, once 30W wireless flash charging is popularized on a large scale, it remains to be seen how users will accept and use it.
