It says it's 12V and can't imagine it not being so. There are devices that make 12V from 5V. It likely won't produce much current at 12V though.

If it's this one:

Specs say "Output:12V 0.8A Max".

IN my bi-annual Migration I hear very little from Truckers any more.

Now I've heard some DOOZIES from Fellow RVers here in the park.


Home is where I park it.

My Favorite CB study (Published so I can talk about it) May or may not be true. there are several.. .Issues.. With the so called facts.

Supposedly a rapist was using CB to lure his victims to the woods.

His last "Victim" was aware of this.. as She was a Police Detective working on the case.. She also was not a victim.. She did, however, arrange for him to have a "Date" with one of the city's more honorable Citizens (Yes your Honor NO Your Honor).

USB is 5V but as I said above, there are devices (IC's) that convert 5V to 12V. The IC's I work with regularly have onboard circuitry that generate +8.5V and -8.5V from a 1.2V supply.

All USB outlets are 5 volt, but the cord has a DC-to-DC converter in it that bumps the voltage up to 12 volts.

Correct!

My BIL for nearly 20 yrs was a truck driver, NONE, ZERO, ZIP of the trucking outfits he worked for had or used CBs in their trucks.

My Neighbor across the street from my house drives triaxle dump trucks, no CB antennas on it..

MANY of the trucking companies now days rely on BUSINESS BAND RADIOS AND CELLPHONES for communications.

CBs are so 1950's technology and the peak was late 1970s when it comes to manufacturing and sales..

Now days you have no real manufacturer choice, pretty much all the manufacturers of CB have gone belly up or exited the business, that SHOULD SPEAK VOLUMES.

You might find some Unidens and some Chinese no name imports but the heydays of CB is long gone and never coming back.

I have a real nice 1980s Radioshack 40 channel mobile CB that I could not even give away for $10, it was a $179 radio back in the 1980s..

If you WANT weather, you can buy a WEATHER RADIO WITH WEATHER ALERTS..

I have three CB's in this RV
one is a Midland hand held. no batteries in storage
one is a high end COBRA on chan 19. Well placed NGP (Radio Shack) antenna. This is the one that warned me of the two fatal accidents and the resulting hours long traffic jam I did not endure thanks to the radio.

And the 3rd (on channel 13 with a very poor antenna) is a 1980's Radio Shack. It is a very nice radio.

Back in the 70's there was a lab run done by an independent lab on Johnson, Cobra and Radio Shack.

Johnson and Cobra #1 were best
Johnson and Cobra #2 were the equal of Radio Shack #1 in all specs save one
Johnson And Cobra #3 were the same price as Radio Shack's #`1 (That was the one spec)

And as you marched down the rankings that held
Radio Shack radios were as good as Johnson And cobra one step lower but priced 2 steps lower so more BANG for your BUCK.

I'm often temped to move the RS to 19 Use the Midland on 12 and convert the Cobra to 10 meters SSB ham band. But not sure how hard that would be. Easier I suspect to convert the older radio (Swap a couple parts and re-tune) but it is AM only.
