Im looking for a plug to put in a wall socket and im trying to use an older cobra29 cb radio. Can you help?

Hey AlexJacob

a mobile cb radio like the cobra 29 requires 12V DC, to plug the radio into the wall you need a Power Supply. A small 5 amp power supply will help you. Their is no plug that goes Directly from a Mobile CB rado into a wall. You will need to plug a power supply into the wall, Then take the power chord (red and black with 3 prong [o oo] and connect red to red on the power supply and black to black on the power supply. Unfortunatly a cheap power supply will be $50+ check your local radioshack
