This is an expansion power unit specifically for the Toyota C-HR. I used it for about six months. It is designed exclusively for right-hand drive C-HR (ZYX10/NGX10/50 series) vehicles. It fits perfectly in the center console storage compartment and doesn't detract from the interior's atmosphere. It allows you to add two sockets and two USB ports (reversible type). The USB ports have an auto-recognition function and can charge tablets, smartphones, and other devices. You can use it by plugging the car plug part into the accessory socket and attaching the main unit with double-sided tape. Please prepare the double-sided tape for installation yourself.
