I wanted to hook this Insignia Vehicle Power Adapter Splitter to add an extra outlet. This is the only splitter I can find locally...

Then I wanted to hook up this Anker 50W 5-Port USB Car Charger to charge my iPhone and iPad if needed.

Then in the second outlet on the Insignia splitter I wanted to hook up the NAVISKAUTO Monitor.

This is what I’m trying to accomplish.
