OPPO Find X3 has improved the fast charge and added support for WLC wireless charging protocol. This function is rarely carried on other mobile phones. It can charge mobile phones without wireless charging function, but it requires the mobile phone to have NFC function, and the charging speed of this process is very slow. If we say daily, we must not be able to meet the demand, because now everyone has been used to fast charging, even the iPhone has no way to 20W, so we can see how necessary fast charging is for our lives.
You can use them together. But the efficiency will be slow.
