Type-C Version Disadvantages:
     1) Poor economy 
     2) High requirements for soldering skills
     3) Low trick success rate and C to C lines generally do not support this protocol. Trick 
will not work if the LED does not light up. It is recommended to keep the C port connected and try plugging and unplugging the charging cable multiple times.
To prevent pin bridging, it is recommended to heat the pads until the solder melts and shows a clear metallic luster before placing the Type-C female connector.
