I’m looking at clearing down some of the power bricks that are in my homelab along with plug requirements. There’s 3 devices that run off of 12v, so the current idea is to buy something like this:
https://uk.ugreen.com/products/ugreen-nexode-200w-usb-c-gan-charger-6-port-desktop-charge
And then this: https://www.amazon.co.uk/gp/product/B0B9FDZX7P
With the aim of powering:
- Beelink Mini-S12
- Virgin Media Hub 3 (this is the worst power brick)
- asus dsl-ax82u
- Raspberry Pi 4 (no converter needed, but will eliminate a plug)
I’m aware this is a single point of failure, it will be plugged into a UPS. I’m just wondering on the viability of it all.
Keep us posted op
Have you looked at Poe adaptors? You can get them that take in Poe, give out ethernet and 12v, the only concern may be current capabilities.
I would step out of the USB / PC realm and look just at DC power supplies. Like this guitar DC/Barrel power source: https://www.amazon.com/Donner-Guitar-Supply-Isolated-Output/dp/B00WHLLDWO/
NOTE: I just google for “Multi DC power supply” and found that. Point being. I have zero experience with that power supply, but DC power has been around WAY long than USB and it is very well supported across many industries. When it comes to DC, you really only need to look at the Volts too, forget the Amps. I’d say only the Beelink needs to be considered in Watts everything else just V’s.
I took a look around for high-ampage 12v DC power supplies. There’s a few out there which do 12v at 12.5a and provide a DC jack splitter (https://www.amazon.co.uk/12V-12-5A-Power-Supply-Replacement/dp/B0BQJ4B8FT), but that’s using a brick power supply.
The reason I’m keen to get rid of the power bricks is due to the space constraints I have. If I can replace 4 devices bulky power supplies with 4 USB plug ones (like this https://www.amazon.co.uk/gp/product/B08CDDSVN4) then I’ll be happy.
If I had more space then I would absolutely go for something like this: https://www.amazon.co.uk/Surom-Universal-Regulated-Switching-Computer/dp/B072J97N8T and custom-do my cables.
I did similar, but I got a DC UPS and it’s running: 2 Odroids (like Raspberry pi), a wired router, and a 16 port switch. (edit: as seen here https://ibb.co/album/Jxrb06 )

At 12v you can draw only up to 1.5A.
Ugreen chargers will reboot ports to distribute power to all ports (so all devices will be rebooted)
I bought 12v trigger board from AliExpress for different thing (medical device) since its own battery was 150€ and using usb-c pd brick was 1/5 of the price.
Works really well, no complaints from here. It takes 2A of current only so that might be limiting factor.
