Can I use lightning to 3.5 and charge

I also use the Belkin in my car. I only have a power port and an AUX port so. I haven't had any issues with it. And I like the fact that now, rather than having to plug in two things when I get into the car, I only have one.

Just make sure that it's Made for iPhone certified and you'll be fine.

AS long as you are connected to a power source.

I have 2 made by Belkin and put them through their paces. They do work.

Benefits. I tested that out with my 6S Plus and it still works. But then the 6S Plus has the headphone jack. The last of it's kind.
