Installed 4-port USB socket in console. (Pics included)
I am installing a 4-port USB socket in the console (2016 W212). It will go into the otherwise useless ashtray, properly and tastefully built to look like it is fully integrated with the car. (Pictures later)
Meanwhile, I have a question for you electronics wizards... Can I simply solder the pos/neg wires from this new unit to the pos/neg poles in the existing cigarette lighter socket? I can run a neg to ground in the console and a pos to an unused, switched slot in the left-dash fuse block if I have to, but would prefer not to fish a wire under the dash. (The existing lighter socket is being used for a radar detector, until I can decide whether to hard wire it)
A cigarette lighter is a simple device, so I'm thinking I can add (essentially) a second cigarette lighter location (powering the USB assembly instead) in series with it in the existing lighter socket, provided that 12v power will be the same in both. So I'm open to electrician advice. TIA. .

Conceptually the positive and negative wires could be attached to anything that meant the voltage/amp specs. You have to be careful that all the devices when attached will be within the specs. There is risk of course.
I recall someone posted a while back about hardwiring a USB hub into the center console by tapping into the wiring for the 12V running to the rear. Don't recall the details or if they were even successful.

Does anyone know if the wires on the lighter sockets (forward console or console rear) are soldered in place, or are there connector clips?
haven't had time yet to disassemble the console to look.

they are usually a right angle three slot connector. If the socket is illuminated it will have all three active prongs. Only two prongs will be active for one that is not illuminated.

Well, this project is done. Thanks to all for the suggestions. Not only do I have a 4-port USB hub, but also a two finger-wide cubbyhole for spare change. What a way to use a worthless ashtray...

Getting the console apart to pull the center console segment was a PITA, but thanks to searching several You-tube videos, the procedure was tedious, but not horrible. But I forgot to take pictures, cause I wanted to get it back together before I forgot how I got it all apart.
The wiring is bisected with connectors so the ashtray can be removed easily as needed.

My 2016 E-Class did not have it... but I do wonder if the newer cars (any brand) will adopt USB power port stations as STANDARD equipment? Everyone who drives a nice car will have a cell phone... every couple or family will have two or more. Not to mention tablet and laptops for passengers. So, I think the need for device charging while on the move is just as important as having cup holders (if not moreso).
It used to be that Mercedes (all the German marks, really) were late adopters of convenience features that distracted from driving... My 2001 MB had cup holders as an afterthought, for example. But today, the Command system offers three data inputs (2 USBs in the console box and an SD slot in the dash) which is great for music, etc, but worthless for charging. I think Mercedes can be just as forward-thinking and generous by offering built-in charging stations as well.
As more people give up smoking the cancer sticks, it makes the space reserved for an ashtray more redundant and archaic. Might as well use the space for more positive purposes, IMO.

I'm impressed with your skills! Have you thought about adapting your idea such that the center console's sliding door doesn't have to stay completely open to access the USB ports? Maybe simply rotating them would the ticket?
I'm nowhere near your level, but wanted a sleek USB charging cord option. I didn't like the idea of routing it from my armrest box, so I focused on the ashtray cig lighter / power port. By using a low-pro USB cig plug, I can keep the center console's sliding door closed or even 1/2 open while using it. That was important to me.

I see you have a rubber mat in lieu of the useless ash tray. That's cool, too.

You’re right, I don’t put drinks in the passenger side drink holder - unless I pull the charging cable out (it’s on a cheap keychain style winding mechanism).
You also keenly pointed out the rubber mat in place of the useless ashtray. Its a genuine MB part that I bought online. I’ll update this post with the p/n on the underside of it. Not sure it’s better or worse than the ashtray, but it’s different.

Actually, the rubber mat would be very helpful for anyone using the low profile plug solution. With a short cord, the phone can then be placed in the ashtray space, resting on the (grippy) mat so it won't bounce around/mar the phone, etc. The mat also prevents small items falling (irretrievably) through that 3/4" hole in the plastic console underneath, never to be seen again (or worse, cause rattles).. Good idea, so p/n would be appreciated.

Merc p/n A204 683 05 94 is a perfect fit for my N. American 2012 W212 E550 sedan.
I got the idea from this thread: https://mbworld.org/forums/e-class-w...placement.html

Thanks for the part number, Johnny Rad. I will order one of these soon.

Is the Ashtray delete part: A204 683 05 94 compatible with 2016 W212?
In thread:https://mbworld.org/forums/e-class-w...placement.html, people have said it is not compatible. Can you confirm before I order one?

2126890096, 2046830594 both are applicable to your 212.067 even though online sources may claim 204 is not, here’s the difference in addition to cost (212 shown first):
