     DETAILED DESCRIPTION 
       [0009]    It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure. 
         [0010]    Several definitions that apply throughout this disclosure will now be presented. 
         [0011]    The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
         [0012]      FIG. 1  illustrates two electronic devices in accordance with an embodiment. The two electronic devices can include a first electronic device  300  and a second electronic device  500 . The two electronic devices can be charged by a wireless charging device  100 . The first electronic device  100  and the second electronic device  500  can be a smart phone, a tablet computer, or a laptop computer, and so on. 
         [0013]      FIG. 2  illustrates the first electronic device  300  in one embodiment. The electronic device  300  can include an enclosure  310 , an electrical coating film  320 , a connector  350 , a printed circuit board  370 , and a rechargeable battery  390 . The enclosure  310  can include a grass substrate or an acrylic substrate. The electrical coating film  320  is coated on an inner side of the enclosure  310 . The electrical coating film  320  can be an indium tin oxide (ITO) film. The ITO film can be deposited on surface of the enclosure  310  by Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD). A thickness of the ITO film is about 0.7 millimeter. After the ITO film is coated on the enclosure  310 , the ITO film can be etched to form a wireless charging circuit to receive the wireless power signal from the charging device  100 . 
         [0014]    The connector  350  can include a pogo pin. The pogo pin is used in electronics to establish a connection between two printed circuit boards. The pogo pin usually takes the form of a slender cylinder containing two sharp, spring-loaded pins. When pressed between two electronic circuits, the sharp points at each end of the pogo pin make secure contacts with the two circuits and thereby connect them together. The connector  350  is electrically coupled to the electrical coating film  320 . 
         [0015]    The first electronic device  300  can further include a flexible contact  330  for buffering contact of the connector  350 . The flexible contact  330  is attached to the electrical coating film  320  through an anisotropic conductive adhesive  335 . The connector  350  electrically abuts the flexible contact  330 . The flexible contact  330  can prevent direct contact of the connector  350  and the electrical coating film  320  to avoid scratching the electrical coating film  320 . 
         [0016]      FIG. 3  also illustrates the first electronic device  300  in one embodiment. The printed circuit board  370  can contact the connector  350  and is coupled to the rechargeable battery  390 . The electrical coating film  320  can receive power signal from the charging device  100  and transmit power to the printed circuit board  370  through the connector  350 . The printed circuit board  370  can charge the rechargeable battery  390  or supply to a system of the first electronic device  300 . 
         [0017]      FIG. 4  illustrates the second electronic device  500  in another embodiment. A wireless charger device  400  can be integrated or removably mounted to the second electronic device  500 . The wireless charger device  400  can receive power signal from the charging device  100  and charge second electronic device  500 . The wireless charger device  400  can include a base  410 , an electrical coating film  420 , a connector  450 , a printed circuit board  470 . The base  410  can include a grass substrate or an acrylic substrate. The electrical coating film  420  is coated on an inner side of the base  410 . The electrical coating film  420  can be an indium tin oxide (ITO) film. The ITO film can be deposited on surface of the base  410  by Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD). A thickness of the ITO film is about 0.7 millimeter. After the ITO film is coated on the base  410 , the ITO film can be etched to form a wireless charging circuit to receive the wireless power signal from the charging device  100 . 
         [0018]    The connector  450  can include a pogo pin. The connector  450  is electrically coupled to the electrical coating film  420 . 
         [0019]    The wireless charger device  400  can further include a flexible contact  430  for buffering contact of the connector  450 . The flexible contact  430  is attached to the electrical coating film  420  through an anisotropic conductive adhesive  435 . The connector  450  electrically abuts the flexible contact  430 . The flexible contact  430  can prevent direct contact of the connector  450  and the electrical coating film  420  to avoid scratching the electrical coating film  420 . 
         [0020]    The printed circuit board  470  can contact the connector  450  and is coupled to the rechargeable battery. The electrical coating film  420  can receive power signal from the charging device  100  and transmit power to the printed circuit board  470  through the connector  450 . The printed circuit board  470  can charge the rechargeable battery or supply to a system of the second electronic device  500 .
