This Air On Board style socket is a versatile in-vehicle accessory that combines a digital voltage gauge with both USB-A and USB-C charging ports. It is designed to be installed in a spare switch blank on your vehicle's dashboard or centre console, but can also be fitted to custom panels or in the cargo area to provide convenient power and battery monitoring.
While this socket is usually installed as a new accessory, it may require replacement if it suffers from physical damage or electronic failure.
