Due to long distance commute everyday, I'm heavily relay on usb charging on cars, Model 3 is a perfect commute car, but the front row charging is too slow for modern devices.

I tested the two usb ports below dashboard, with an 30% battery iPhone 7:
5.01v, 1.14a, total 5.71w.

and for an 50% iPad:
5.01v, 1.28a, total 6.40w.

So I followed @fseir 's video and did a quick work:

First I bought an anker 12v 5 ports hub, total output 5v/10a, 5v/2.4a each:

It's very easy to remove the cabin sides, and cables are fit perfectly within:

I cut a small pieces of plastic and insert the hub wire into front cabinet, applied the double side tape and attached it to the back of the mobile phone charging plates:

And here is the result:
For iPhone 7
4.97v, 1.42a, total 7.1w

for iPad:
5.15v, 2.3a, total 11.84w!

This also solve my problem for dashboard cam:

Now with 4 cables plug-in, I can finally doing waze with charging:

This is the final result:

Strong work!! I plan to do this, as soon as I get my M3, so thanks for the proof of concept! Wasn’t sure if a thicker USB cable would fit in the side channel, but it appears it did. Did you have any trouble exiting the red cable from the channel, into the charging dock bin? In one of the photos, it looks like the cable is slightly compressed at that spot.

I assume that’s where you had to cut a small chunk out of the liner and plastic?

@privater Where is your dash cam cable routed? I see where it enters the side channel on the right, but I can’t see where it goes from there.

Any ideas on how to hide the cable to your phone mount?

Yes, I noticed that too, so I did it again with dremel to cut deeper on the sides, so don't make the same mistake I did:

Sure, I always hide dashcam cable from edges of the top window:

I then hide it under the rubber water seal:

After it reached the passenger door, I use the cable stickers to attach them under the glovebox then went into charging hub:

I bought a gizmo for our cars that turns the 12v cigarette lighter socket into a 5v 3 Amp USB socket. Works great for my Pixel phone. I get 15 watt charging. The adapter has two USB sockets but I do not remember if both can be used together and still get 15 watts each.

@privater,

Which Wi-Fi hotspot are you using? Looking at picking one up for my dashcams....

@privater,

Same.
I've looked around, but I can only seem to find ones that have an internal Li ion battery. Being that I live in Texas, I'd rather not leave anything in my vehicle that has a Li ion battery. The cabin temp in a vehicle in the hot summer is way too high for my own comfort.

Ideally I'd like a WiFi hotspot that simply is powered by the 12V supply that I can set and forget. When I power on the car (and dashcam) it powers on as well.

EDIT - I'd like to not leave any Li ion batteries that aren't properly thermally managed. And while I'm sure most consumer gear will not have problems, I'd rather not risk it.
