Agreed. Xiaomi's wireless charger uses a universal charging protocol, in addition to the use of Xiaomi mobile phones, can also be used on other brands of mobile phones, because it has made a special adaptation to the protocol of other models, as long as it supports wireless charging mobile phones can use it to wireless charging. The OPPOfindx3 can use Xiaomi's wireless charger.
It's alright to me! Wireless charging of mobile phones on the market is a standard! QI standard!
