How much power does a cb radio use? Although the FCC limits CB radios to a standard 4 Watts of power, there is an exception. If you want the best range, you may want a radio with single sideband (SSB) capability. SSB radios, such as the Cobra 148 GTL transmit at approximately 12 Watts, or three times the normal power.
How much power does it take to run a CB radio? Actually, it states 0.3 amps (300 ma) squelched, and up to 1.2 amps with full audio output.
How many amps does a 50 watt radio draw? A typical 50 watt land mobile pulls 0.5 amps in receive and 12.5 amps in transmit, and normally has a 15 amp fuse. Higher TX power ham radios need more (check the specs in the book). I suspect either your power supply isn’t delivering enough amps at the required voltage, or the wire size is causing a voltage drop.
How many volts is a CB radio? Although 12v is the ‘nominal’ voltage for a car electrical system, with the battery fully charged and the engine running and no electrical loads, you shouldn’t measure any less than 13.2v, hence the reason that is the usual voltage for a CB power adapter.
