Plug CB radio into USB port instead of cigarette lighter

I want to permanently mount my CB radio inside my center console. How do I power the radio?

I have a 2019 JLUM with aux switches. I have a Uniden 520 cb radio that has 1 black and 1 red wire coming from the back of the radio. The only power source inside the center console is a USB port.

I have three powering options and I'm seeking some feedback so I can have a clean install---(no showing wires).
  1. Solder a cigarette lighter plug onto the red and black wires of the CB radio and have that nasty cord run from the console to the dash (yuk)
  2. Hard wire the radio to one of the aux switches and snake the wire under the carpet up to the passenger footwell--uses a precious aux switch
  3. Power the radio with the USB port that's inside the center console (either solder a usb cable to the radio or get a usb-to-cigarette adapter)
I'm hoping I can do #3. Will I burn up my USB port? Will I burn up the CB radio?

I already do it the #1 way and it drives my OCD butt crazy that there's a wire running from the console to the cigarette lighter. #hidethewires

[*]Power the radio with the USB port that's inside the center console (either solder a usb cable to the radio or get a usb-to-cigarette adapter)
I believe the USB spec is 5V at a maximum of 500mA. I suspect that will not be enough for your CB.

Perhaps you can power the CB from the fuse block, and use the power switch on the CB.

Yep, any USB is only going to give 5v, amperage here doesn't even matter, that CB needs 12v.
Without 12v CB will never turn on

To install that CB PROPERLY, it needs to be powered either directly from the battery or, best, via the 12v input lug inside your Power Distribution Center. Other sources of power either can't provide enough current or they're electrically noisy.

This is the 12v input lug inside your PDC...
