Connector(s) : USB C Male to Male and Female 1 pair 5.5*2.5mm DC Power Plug. Length: 8 INCH
Male and Female 1 pair 5.5*2.5mm DC Power Plug port which need 12V 5A DC power
Note: Note:Sometime the only snag is sometimes it doesn't accept 20V immediately, so you just set it to output 9V then change it to 20V. This is not a problem with a cable.
USB C Plug easily used without checking for the connector orientation
