Most CB's, Amateur radios, and accessories are designed to work off a 12V supply. So in order to use them at home you will need a suitable power supply.
We stock a large range of power supplies from 3A to 40A. It is important that you choose a suitable size supply for your needs. Buying one smaller is false economy - at best it will not work correctly and at worst you will blow it up and possibly also damage your radio.
As a rough guide to the size of power supply you will need:
3A = 5W, 5A = 30W, 8A = 60W, 10A = 100W, 30A = 200W
