The QI Wireless charging device is divided into two parts. One is the QI wireless charging transmitter, one is the QI wireless charging receiver. They can't be separated from each other. If your phone has a built-in QI wireless charging receiver, you just need to buy a QI wireless charging transmitter. If your phone has no built-in QI wireless charging receiver, then you also need to buy an external QI wireless charging receiver, so that your mobile phone can achieve QI wireless charging.

Under the existing technical conditions, heating is a normal phenomenon when the charger is charging. No wireless charging can completely avoid the heating of the coil. All the products are tested strictly. Please use them without worry
