The charger is a common charger and is not a wireless charger.

CN201510401468.6 discloses a built-in charger of a mobile phone based on graphene technology, which comprises a miniature AC-DC conversion circuit and a folding AC power supply pin. The core of the miniature AC-DC conversion circuit is an ultra-thin electronic transformer, a new graphene material is introduced into the electronic transformer, the thickness of the transformer is less than or equal to 4mm, and the requirement of the thickness of the inner space of most common smart phones can be met. The charger is a common charger and is not a wireless charger. The mobile phone is provided with a built-in charger and is not provided with an external charger.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims at providing an electromagnetic induction type wireless charger.

The utility model provides an adopted technical scheme of its technical problem is:

the utility model provides an electromagnetic induction formula wireless charger, wherein, the panel of wireless charger is graphite alkene panel or graphite alkene composite panel or graphite alkene combined material panel.
