Thanks for your reply. I guess I should have called it a battery maintainer by Porsche.
I plug it into the cigarette lighter to keep the battery charged. There is power to the lighter socket, it's a 1999 Base model Boxster.
The maintainer has LED lights.
I did try it on my 2018 Chevy Malibu in the 12 volt socket, (they don't put cigarette lighters in cars anymore) and the top row wouldn't light up on that car either. It may not be equipped to charge through the 12 volt socket like the Porsche.
