I mean where the power cord connects to the unit. If you look at the first picture here you can see that this unit uses an AC power cord. I’m looking for something that uses a DC barrel connection for the power cord.

I’m struggling with Amazon. The units have bad pictures and missing spec info. When I find one with specs that say DC 12v I find an answer in the question section that says it is AC.

When I find one that is clearly DC it has bad reviews.

YouTube searches are also limited in results
