Adding USB ports to custom console

[Athecal]

 

TL/DR: looking for buck converter power distribution board that could take a single input 14.8v and have enough outputs for 2 usb plugs with 2 usb c  ports on each, 1 3pin molex 200×200mm noctua fan, 4 wireless qi2 charging boards/coils. As well as any recommendations on these items.

 

 

So I am building a custom center console for my 2002 gmc sierra crew cab. After replacing the rear split bench with captain chairs from the middle row of a Yukon XL and removing the jump seat/console from the front seat area I plan on this console reaching from the dash to the read firewall.  It will contain 2 sql12s d4, 2 NVX VAD1700.1 monoblocks each pushing ~1350w to one sql12 wired to 2ohm. 2 NVX VADM4 one will power the 8in silver flute midbass in each door, the other will power a dayton audio fabric dome mid and fabric dome tweeter that are going into custom A pillars. With a Helix DSP.2 at the center of the signal chain. The power is being supplied by a 270a alternator and 2 LTO battery banks I built. One installed in the stock location the other installed in the stock location for a second battery had my truck been a diesel.

 

What I am trying to do now is find a way/find a part/product to take the 14.8v coming from the battery and allow me to split off a regulated 12v to a few USB plugs for charging phones and whatever else, and I am making insets/trays into the console for people to put their phones so I want to put wireless qi2 charging pads under them so everyone's phone will just automatically charge when dropped in them. Have any of you done something like this? I would appreciate any recommendations for specific parts used in your builds that turned out to be good, or any warnings to steer me clear of bad quality components. I mostly would like to know of a main buck converter board that could take a single input and have enough outputs for 2 usb plugs with 2 usb c  ports on each, 1 3pin molex 200×200mm noctua fan, 4 wireless qi2 charging boards/coils. As well as any recommendations on these items.

 

I have a 500v/500a volt/ammeter display I am going to put into the console as well but no lighting effects or anything like that.

 

Thanks for reading and taking the time to share some information.

All those chargers you mention exist as car accessories which will directly take 14.4V, you just need a small distribution block to have one input and multiple outputs to the devices you want to power, for the noctua fan it will depend on the input voltage, those usually take 12v and likely can be directly powered with 14,4V and if not you could then add a small regulator board for it.

 

Designing a custom central DC/DC step down is totally unnecessary, inconvenient and would take space, also would prevent future expansion. Also premade accessories individually include over current /short circuit protection that is absolutely necessary.

I hadn't fallen quite this far down the rabbit hole yet fortunately. It was tickling the back of my mind though. I guess my brain wasn't functioning properly. I kepy looking at different little panel mount boards on amazon and they all said 12v input. Or 12/24 and in my mind last night this was telling me it was not just a constant voltage variable current situation but that this voltage was critical and absolute when everything I know about electronics agrees with you. I'm stepping so far outside of my comfort zone with this build that I find myself second guessing and quadruple checking things that are just standard operating procedures. Thanks for the reality check.

Use accessories that specifically state "for car use" and you don't have to worry while you are in the 9-15V region.
