Is it possible to use Mi 20W Wireless Car Charger to charge when using the protective case of mobile phone?

Explanation:
Mobile phones with protective cases are also supported to use Mi wireless car charging, but the thickness of the protective case should be less than 4mm. If the protective case is too thick, it will not be able to charge.In addition, the inside and outside of the protective case must not contain metal materials. Xiaomi wireless car charging supports metal foreign matter detection, which can avoid high temperature or other abnormal situations caused by metal during charging.
