The USB extension with separate charging current is ideal for connecting multimedia devices (e.g. ceiling monitor) that have a USB port for playing media, but when connecting a hard drive, the existing USB power supply remains weak and the drive will not work. The car's power supply (supported by both 12V and 24V) is connected to the plus and minus and the USB extension socket outputs a stable 5V at a maximum of 2.1AMP.

Can also be used simply as a USB charging socket, charging your phone or even a tablet.
There are several installation options, it can be completely recessed or, in addition to the cigarette lighter, installed under the dashboard using the included clamp.
