12 Volt Power Supplies
A CB radio can be connected to a 12 volt power supply for use outside a vehicle for testing, or to use the radio as a base station. 12 volt power supplies plug into a standard 110 volt AC wall plug. They convert that into 13.8V (commonly known as 12 volt). Typically, they either have positive and negative posts to connect your radio, but some also have a "cigarette lighter" plug. A CB radio outputting 4 watts will not need a power supply larger than 5 amp. We carry larger and smaller power supplies for other applications.
