アルミニウム合金電話ホルダー磁気 magsafe ワイヤレス充電

Magnetic charging, also known as wireless charging, is a new charging technology that uses a magnetic field as a signal and energy transmission medium to achieve wireless transmission of electrical energy between the receiving and transmitting ends. Magnetic charging method uses magnetic materials to generate a magnetic field, and establishes magnetic field output and input at the transmitter and receiver. By adjusting the output magnetic force and the sensitivity of the receiver to the corresponding magnetic field, the electrical energy from the transmitter is transmitted to the receiver, and a stable electrical energy input is obtained at the receiver. Magnetic charging refers to setting up a set of magnets between the transmitter and receiver, using their generated magnetic fields as signal and energy transmission media to achieve the charging process.
