Questions about charging my mobile devices

OK. I've cut out of my original thread here my long and wonderful history with mobile devices. As I said, I hate my Apple I-Phone 4S. But I don't need advice to get an upgrade. I may spring for an Android phone later or in a year's time.

It boils down to this. I have the I-phone 4S. And I have a Vankyo MatrixPad S7 7-inch tablet, which I'm integrating into my 21-year-old car -- maintained, babied with TLC, and in progress of being retro-fitted for the 21st century.

So I am investigating the purchase of a $15 item: A dual port USB A cigar-lighter charging device, or perhaps (better) -- a unit that would install in my dashboard after drilling a 3/4" round hole (I had seen such items over the last couple months).

Some of these units support "Quick Charge" and can serve up a total of 6 Amps of current allocated to both ports simultaneously, or 3 Amps each.

Given the age of my I-phone, or the fact that my Vankyo 7" tablet was first released in the last year or two, I want to know that these charging plugs will not damage my devices, while enabling them to charge faster. Actually, the I-Phone hardly matters. I'm much more keen on ensuring long life for the tablet.

Any thoughts from those of you in the "Beam-me-up-Scotty" Mobile-Thumb-typing Millennial generation? Or even from some old f*** like me?

Somebody has to know something about this. Here. Here are some examples of what I'm looking at :

You should be fine. The iPhone and tablet only draw as much power as they can handle.

I always seek second opinions in fields for which I was not formally schooled. But -- that's good -- as much as one would expect. They draw what they can -- no more no less.

Thank you very much for suffering through one of my often longwinded thread-posts.

Those two devices I saw don't have many reviews, but then -- the mainstream people aren't interesting in cutting a hole in their dash to spec and hardwiring a charger like that, maybe even installing a three-pin switch. [Come to think of it, a vacant pair of USB ports wouldn't need a switch.] Something like that -- could be a couple hours work -- I might take weeks, doing it in parts. So I'm thinking "which one?" The one with the nifty LED lights? or the other one? Maybe I'll make up my mind tomorrow! ;)
