If the coil on the case is Qi compliant and aligned with the receiver inside the phone, it can be charged via wireless charging. However, it should be noted that the power of the coil should match the output power of the charger, otherwise the charging efficiency will be affected. In addition, if the case is too thick or the material is not transparent, it will also interfere with the transmission of wireless charging, resulting in reduced efficiency. Therefore, it is best to confirm the compatibility and quality of the phone case before use to ensure that the charging effect is good.
If the coil is completely glued to the phone case and equipped with the appropriate wireless charging technology, it can be charged wirelessly. The coil on the phone case plays a role in transferring energy, so that the phone can get power from the wireless charger, but you need to make sure that the distance and position between the coil and the charger are in accordance with the recommendations of the charger manufacturer. In addition, the material of the phone case will also affect the effect of wireless charging, so it is necessary to choose the right shell material to ensure the charging speed and efficiency.
The coil attached to the phone case can achieve wireless charging, but the premise is that the phone supports wireless charging. If the phone has this function, it can be charged by placing the phone on the charger, without the need to plug and unplug the cable. Therefore, if you want to use the coil on the phone case for wireless charging, you first need to confirm whether your phone supports wireless charging.
