This is an adjustable black car phone holder. It can hold smartphones up to 9 cm wide and has the following additional features: * Cigarette lighter socket * USB Type-A 5V/2.4A x 2 The main unit connects to the cigarette lighter socket, allowing you to retain the socket while expanding to two USB Type-A sockets, making it a convenient product for holding your phone. The bottom of the phone holder is open so you can charge your phone while it's held in place, allowing you to plug in a cable. There's also a hook on the arm to keep the cable in place. Please note that some thick smartphones, such as those for outdoor use, may not fit in the holder. The arm itself is made quite rigid, so it should be able to hold heavy items without bending.
