I've got a monitor which takes 19V 2A (AOC I2381FH) that I've lost the power supply to. I've got a power supply which will fit which says it produces 12V 2.5A which sounds like it might work.

Would I likely damage my monitor by using this? Trying to find a replacement supply seems difficult for it.

Check the info label on your monitor to view the acceptable input voltages.

My guess is that it won't work as 12V won't be enough.

You need a 19V, 2A power supply. The required power is 38W, the 12V 2.5A can only supply 30W.

  • Thanks, is there any way of knowing what kind of connector will fit in it? – Joe Simpson Jul 07 '20 at 10:42

    If you have to buy someting anyway, why buy random power supplies if you are unable to determine if they are suitable or not. Why not buy a replacement power supply from the monitor manufacturer, so you know that it's compatible. – Justme Jul 07 '20 at 10:46
  • They don't seem to sell them unfortunately, at least not in the UK – Joe Simpson Jul 07 '20 at 10:52
  • 19V is (or used to be) a standard laptop charging voltage - I have several old chargers with that output. You should be able to find a universal charger on Fleabay or similar. It is also likely that your monitor has a standard tubular connector, but you need to check. – user131342 Jul 07 '20 at 11:39
  • I bought one but it doesn't fit sadly. I have no idea how to really check if it fits properly or not :/ sadly it's not like usb where it's relatively standardised haha – Joe Simpson Jul 07 '20 at 11:43

    @JoeSimpson: Barrel connectors are somewhat standardized. You need to measure the diameter of the center pin and the diameter of the hole for the barrel. Use a caliper. – JRE Jul 07 '20 at 13:11
