A range of 12V power supplies for operating mobile equipment from the mains.

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
