Found this trick from a sportage owner. If you have a wireless AA or Carplay adapter that doesn't turn it self off like mine you either need to unplug it or put a switch on it so it won't keep connecting and disconnecting for hours in your house. But if you buy a USB Y cable and a USB power blocker you can make it automatically power off and on with the car. Put the Power Blocker on the Ioniq's USB port, it will pass though data but not power. Then plug the other side into the lighter socket, it only powers on when the car is on. So the adapter only now gets power from the switched lighter socket and not the USB port, so it turns on/off with the car. I tried it tonight and it worked great, powers on with the car and connects to wireless AA then turns back off with the car.

The right angle adapters are optional, I did it to keep the cable out of the way. Or you could also pull apart a USB Y cable and cut the power wire
, leave the data wires.

Power block goes on the left hand USB port, where you would normally plug in the AA adapter. One side of the Y cable then goes into the power blocker, the other side goes into the 12v cigarette lighter adapter. The output of those two then goes to the AA adapter.

Search for PortaPow USB Power Blocker - Only Data, No Power. The Canadian Amazon has it here:h ttps://a.co/d/65D6f9o

Otherwise you need the USB Y cable in OP, and a cigarette --> USB adapter you can find all over the place.

I am confused my USB for AA turns off after about 15 min.

Yes it does. But it will turn on again whenever the 12v battery is refreshed, grabbing your cell phone’s WiFi connection and disconnecting any phone calls or data connections in progress.

The new AAWireless 2 has a button that you can set to stop (standby) when you push it. It will not connect till you push the button to start. When I'm home, I just push to button and when I leave, I push the button and it connects in about 30 seconds.

Thanks to all the posters for the advice as it helped me get this setup on an Ioniq 5 with the Carlinkit 5.0. I had a similar problem that when using only the usb port for power and data, at times my phone would connect to CarPlay while inside the house.

Purchased the Y cable as OP suggested and a flush adapter for the 12V lighter. I have the power blocker on order, but shipping is about a week. So I cut a small piece of electrical tape and covered the power pin on the USB 3.0 male connector on the Y cable. Worked perfectly!

I used the cable from magicable.ca to supply power from the cigarette lighter. Works like a charm.
