Will this work

[jlawson435]

I have a 12 volt power supply
INPUT AC 100-120 v -60 Hz 35VA

OUTPUT
12VDC 1.25A
when plugged in it measures 12.12 volt on meter
will this work to power up a cb radio

 

[TonyV225]

power up maybe but transmit no

 

[mrgumby]

a little low on the output amps

 

[Robb]

a little low on the output amps

I agree.

Wecome to the forum jlawson435
When you transmit on that radio; does the voltage drop below 12v?
If it does, I wouldn't use it. A 4 amp supply @13.8v would be best - can be had used for $15...

Sounds like a wall wart. no go

ok I found this one
input 120v 60Hz
17W 0.14A
output 13V 650mA
when I plug it in it say 19.06 on my volt meter

650mA is .65 of one amp - that won't do. You need 1 amp just to turn the radio on and listen. Depending on the CB - you will need 3-5 amps to transmit w/o overloading the power supply. What model and make of radio is it? Regardless of make/model; you will need at least a 4-5 amp supply. Anything else would cause the radio to be exposed to low voltages and cause damages.

If you run too high a voltage; then you risk damage as well.
19v is too much voltage...don't use it!

No more than 14.1 volts and no less than 13.8 volts.
Most "12v power supplies" on the market today are actually 13.8v.
Remember this: you can get a power supply that has a higher amp rating - the radio will only draw as many amps out of the supply as it needs.
But the voltage is important - and must be matched to the need!

Here is an example of what you need.
You may find a used one for $20 if you look around locally...

I have an Astron RS 20A I will sell for $55 + shipping, it weighs 20 lbs.

Does 16 amps continuous and 20 amps peak.

Excellent price.

RS20A 16 Amp / 20 Amp Surge - Astron - Icom, Laird, Pulse/Larsen, Polyphaser - Kollman Radio Electronics

Astrons have the ability to be used in parrell, and are built like tanks. You can turn up the voltage internally on this model to about 15V with no problem.

If I didn't already have a few, I'd buy this one.


Ha....

Shit, if Mack gives me a break on shipping, I just might.

just get a computer power supply. in the atx type you have to short usually the green wire to one of the black ones with a wire to get it to turn on(on the motherboard plug. the voltages on the dc power plug are often written on the back of the cd player. They are stable, inexpensive and high quality but they don't have short circuit protection so you must be careful when wiring them up. there are many howto's available for googling.

Good idea also, I have 2 extra laying here.
