The wireless charging case does not slow down the charging speed.

Wireless charging is possible with a phone case. The phone case is not affecting wireless charging. Unless your phone case is very thick, it has isolated the thickest limit of the contact between the charging bank and the mobile phone. In addition, you will not be limited in charging, you can directly charge it, and the charging will be very fast, without affecting the charging speed.

The speed is the same as if you don't bring the phone case, so you don't have to worry about these, if you really worry about these, you can also directly remove the phone case when charging, so as to cancel your worries.

Qi wireless charging has requirements for charging distance, and the maximum charging distance is only 10 mm. This is a bit \"blocking\" for Chinese mobile phone users who like to use mobile phone cases, although there is no need to remove the mobile phone case, the thickness of the mobile phone case has requirements, and some charging plates are marked, and the thickness of the protective case should not exceed 3 mm.

Since most smartphones that support wireless charging use Qi wireless charging standard technology. The technology uses electromagnetic induction technology to convert current into electromagnetic, and the phone charges by converting electromagnetic into current through a built-in coil. However, the drawback of this technology is that it will heat up the device, so the use of wireless chargers for mobile phones with phone cases affects their heat dissipation.
How much speed will have an impact, and it also has an impact on heat dissipation performance.
