Wireless charging can change the power of mains jack into the rechargeable waves, then directly charging e- lectronic equipment when we are ender the wireless. If both coils are designed into transmitting terminal and receiving end, the trans- form of inverting input ( current) signals can make the receiving end response the current, it brings electro-magnetic induction and magnetic-electro induction to the full. Wireless charging cable breaks the previous conventional thinking, aims to show wireless char- ging has more advantages than wired. The output voltage of the two normal stable can be designed at the same time and safe charging and fast charging battery in certain emergency situations. Key words: wireless charging; elec
