With the emergence and development of wireless charging technology, resources that are difficult to leave in modern life have become easy to obtain, which will also promote innovative breakthroughs in modern technology, products and business models.

Once there is no power and no place to charge, mobile phones will become useless to users, although they are quite powerful. To achieve complete wireless freedom, you need to cut off the last cable - the power cable.
