There is not such available from Wyze. I’m not sure why you’d need it since each Wyze Cam comes with it’s own power adapter and cable. There are plenty of 12V to USB adapters on Amazon, but the only ones I see would require some manual (soldered) wire connections on your part.
I also am trying to do this. Found this adapter going to try it, I’ll let you know. Conwork 4-Pack 90 Degree Right Angle 5.5 x 2.1mm DC Power Plug Female to Micro USB Male Charge Adapter for Cellphone Tablet Amazon.com
I am actually researching that as well, I am thinking about using this:
I will cut it in the middle and then insert a DC 12V to 5V converter board in between, and solder the 4 wires, hopefully this solution will save some space for the unnecessary wires if using the dashcam powet kit.
Trying to go from 12V barrel connector powered cameras to Wyze V3 Pan. They make an adapter to go from Barrel connector to USB (seen above). So… What about using a 12V to 5V converter after the main power block and before the 4 plug adapter?
I’m going to frankenstein lamp cord with old plugs off of discarded appliances and just use the supplied 120v USB plug. Seems same labor as what is proposed above.
Would be to easy if the cams accepted variable voltage, so the all we would need is the usb to barrel connector. I would think there are hundreds of us out there if not thousands that made the costco Q-see mistake.
