    Can I use one power supply for both my Wii U and my Switch?



    QUESTION: Is there any USB-C Power Delivery box and cable that can safely power the Wii U through this adapter off AliExpress AND power my switch when docked. Wii U requires 15V / 5A, switch requires 15V / 2.5A. I know little to nothing about electricity so I’m wondering if I can use 15v / 5A to power both consoles (even if it’s harsh on the Switch’s battery, I really don’t care)

    CONTEXT: I don’t have enough outlets to have both my Wii U and switch hooked up at once, so I want to be able to manually swap the hdmi and power cables between the two consoles.

    I play the Wii U very often but I hardly ever touch the Switch so I don’t care if this isn’t safe for the switch’s battery but I care deeply about the Wii U so if this is too risky, I’ll just use OEM power supplies and whip out an extension cord on the rare occasion that I use the switch

      thats not how that works, they cannot power eachother. And you cannot go usb c to wii u to power any device, its only wiiu to usb c.

      If the voltages and intensity matched those of the requirement for the Wii u , 15V, 5A in Direct current.
      If you’re asking if hypothetically a usb C cable could power the whole system, yeah it could since usb C cables can now do up to 240W. That’s a lot compared to the Wii U’s needs for 75W.
      Realistically if you wanted this to work you would just need another ac dc adapter

      That’s not really how that works. If you’re out of plugs, just get something like this ([Link](https://www.amazon.com/Protector-Extension-Multiple-Extender-Essentials/dp/B0C6XNMLX3/ref=sr_1_11?crid=LGQ6N0HSUZ5Y&dib=eyJ2IjoiMSJ9.0XWhaMw380FcIkRyiq2RUmEsBmduBP5HGc9VNLuoqQ5nbwpPvRqp3DzCoodPQpIDOYNsrDFjqVsDGpD4aXn3qDUqB4gxHXJiw_g0Gjx1xSfFFu536fIbFns6ECSE45Vg0pF_jR9Pz2uQ_Q2A_JM4M6xllsa51hKLUOILp19FsykD-qUwqbl353OwRl6JRViGYfF01HlRrIlakpqMBcGUmkS8_GlMUsOQ5g3R4qM7F1c.kgREQGOx8z1v-omXmmlYGlCIcUpUnGa1oz1cAWj1BXE&dib_tag=se&keywords=power%2Bstrip&qid=1782881443&sprefix=power%2Bstrip%2Caps%2C220&sr=8-11&th=1))

      I have a 100w plug with two usb c output, each output rated at 50w , both my switch and wii u are modded and overclocked relatively increasing the power draw and yes it works

      this should work in theory, assuming the PD adapter communicates with the power brick. i only mention that cuz i USB-C modded my gamecube, but it uses the funk 12v mode that not all USB-C adapters support. but, you say it’s 15V, which i think is universally supported, so it should Just Work.

      and i looked it up just to be sure, the switch’s AC adapter does use USB-PD, so you should be good to go, assuming this lil adapter works.

      I have my own adapter and it works wonders. It removes the stress of using the brick to power on the Wii U when this thing you can use any USB-C cable for it (even a phone charger works). You’ll be fine.

      I’ve built a custom one of these, and in my experience it only draws about 2 amps including disc usage (maybe a little bit more depending on the conditions)

      With 15v usb C can provide up to 3 amps anyways so you should be fine if you’re using a supported power brick

      Edit: I would like to note that USB C PD also negotiates power requirements before sending any sort of power, and that devices will only take as much amps as it needs according to the situation
