I would like an "Always hot" charging port

Like the title says, has anyone explored how involved it would be to convert a USB or Cigar Lighter port to be able to provide a charging source for a cell phone. I find it interesting that US branded vehicles have this feature but Asian vehicles require the Key on for power.

The USB port for the audio system on my 2017 Sportage is always hot. Don't know about Sorentos.

I asked this question when we first got our Sorento and the answer was, no one knows. I've done it to other Asian cars by jumping a couple of connectors in a relay panel - very simple and free. No one has apparently attempted it on a Kia and so no idea what or where to provide a jumper. I would like the cigar lighter to be always hot but may never happen in this particular car. It was one of the first mods I ever did to my 4Runner to keep my cell phone charged properly and the stick on GPS running at fuel stops and such.

If factory aux port isn't always hot, simply get access to the back of it, disconnect its wires, probe to find its ground wire and hot wires. Cap its hot feed wire. Then, run a new 12 gauge wire from its "+" side, through the firewall and to the battery "+ post. Approx 6-12 inches from the battery post, simply install properly sized 12 volt fuse. For example, device's MAX watts divided by 12 volts, then round up to next available fuse size. re: 3.5 Amp fuse. Hardest physical part is getting access to the back side of the aux plug and feeding the new 12 gauge wire through a firewall hole (using rubber grommet - where needed). But, all this physical work can be done in one's driveway.

5 out of 4 people have problems with fractions..... LOL!

That's how I would have done it in the olden days but today, with all the sensitive electronics, I'm afraid to effectively add an unshielded circuit to the car. Plus, I wouldn't want some owner installed wiring to set off alarm bells with a warranty claim. It's so easy to do given the proper wiring diagrams and it's completely out of site and using the existing wiring but apparently there isn't that much interest in working on what is, effectively, a family grocery getter where probably 95% of the owners will never touch a single mechanical thing on the car.

You can also add on of these. Search on 'add a tap' or similial products. Also note there may be more branches on the ignition power coming off of the power plug. W/O a wire diagram (schematic) cutting +12 ign off the plug could possibly disable other adapters or circuits.

As I do not know your level of electrical knowledge I am not giving any direction or recommendations just another avenue to pursue. .

Thanks for the tip. I just checked the USB port at the front of the Console where I plug my phone in for Android Auto and it is hot. Problem solved.
