Powering Monitor with DC jack over usb-c

Johnny73
Go to solution Solved by mariushm,

There are small devices which you can connect to a USB type-C output and "tell" the charger to configure the voltage to a specific level , like 5v, 9v, 12v, 15v, 20v, or something in-between. 

 

Just the fact it has a barrel jack connector doesn't tell me anything - you need to know the voltage the monitor expects on that barrel jack connector. It would probably be 12v or 18v or something like that, because it would mean they can use mass produced power supplies (laptop adapter style bricks) 

 

Look on the actual power supply that came with the monitor, it will say the voltage and current it's designed for.  Voltage x Current = Power, but the adapter will be designed to supply more than what monitor consumes on average, and it's designed to support monitor at 100% brightness, with devices plugged in usb ports that consume a few watts, and so on ... 

 

For example, here's one of those adapters :  https://www.amazon.com/Type-C-Trigger-Module-Supports-Output/dp/B08LDJBN8P

By connecting the appropriate pads with a blob of solder, you tell the chip on the board to tell your usb type c to change the voltage to the one you configured, otherwise the usb charger will output 5v. See picture below

 

Another example of such adapter/module/board, same concept, solder pads to set the voltage : https://www.amazon.com/Trigger-Adjustable-Voltage-Module-Default/dp/B0B688SKNK/

 

And these are "hardcoded" to 19v or 12v and they're 2.1 ID, 5.5mm OD : 

19v:

https://www.amazon.com/Rectangle-Adapter-Emulator-Trigger-5-52-1MM/dp/B07SJ9SB6Y/

12v

https://www.amazon.com/NFHK-5-5x2-1mm-Adapter-Emulator-Trigger/dp/B0B9RDJ1YK/

 

 

 

Then you solder a cable with the right barrel jack plug to the holes at the end of the board (you see + and - there) and you're in business. 

Examples of cables with plug and loose wires or other connector (you could cut to get wires) at the other end : https://www.digikey.com/short/dr2301w8

Most common formats are 2.1mm ID (inner diameter), 5.5mm OD  (outer diameter)  and 2.5mm ID / 5.5 mm OD

 

 

If the monitor wants 18v, it will probably work with 15v, but would be risky to give it 20v. If it's 19-19.5v, 90% sure it will work with 20v from your usb charger.

Hi, I wanted to power my monitor over usb-c. (I have charger with enough power and amps)

It's LG ULTRAGEAR WK95U and It uses a 5.5mm DC barell plug, so If I used proper cable could It be powered over usb-c?

Thanks

No.

My monitor doesn't use AC.

Then what is your actual part number? Because "ULTRAGEAR WK95U" only returns listings for "LG 34WK95U-W".

SPECIFICALLY, a USB-C output that supports USB-PD. Not every USB-C charger/device is PD compliant. And not every USB-PD device supports every PD level.
