Power supply question how do I find which power supply will fit, I’m able to find dc power supplies with multiple tips but want to make sure to get the right one

You can take it to an electronics store or Radio Shack if you have one nearby. They tend to have a set of tips to identify the right size. Or download the manual from the manufacturer, as it may list the barrel connector size.

Jason Marsh no more radio shack out here and no frys I’ll download the manual if I can find it, it’s an old tv made in 2006

The size is one thing, but then you have to make sure it produces the right polarity. The little symbol - ---(--- + means that the tip is positive. That means when you test with your multimeter it should read 9 (up to 12)V while the red lead is stuck in the hole of the tip and the black lead is touching the outside barrel. And it will read -9 (up to -12)V when the red and black are reversed.

Looks to be a "standard" barrel jack...the simple kind without fancy color tip. Most 12v and 9v Walwart power supplies used this size. Most likely one from a router one will work..and since your pic does't show amps or watts required, it's probably 1amp or less.

 

I just got a multi plug power supply as shown in this pic - on the bottom left corner... look at the very last plug on the bottom... that's the kind you will need.

Giligain I. It’s 1.5 amps I’ll test out my router ones to see if it fits and double check the amperage

If you have a set of measuring calipers you can just measure the pin and shell diameters and the depth. Then find the closest match from this list of the common sizes. Beware of sizes that seem to fit but are a little loose, they will often give intermittent problems over time.

This is why I never toss a wall wart. You never know when you might find a new use for it.

It says it'll go up to 12v. Do you have any old router power supplies? I bet a Linksys one would work

[G+_Jason Marsh]

Jason Brown I think we all have a box of them holding the floor down in case of hurricane/tornado/sharkpocalypse...

I wouldn't be surprised that a lower voltage may even work provided it can juice the amps enough for the load.

 

I got this Acer monitor needing a 19.5v input, but next day's resale shop, I could only find a 18v supply having 0.8a spec...but did already have the correct barrel jack size needed to match the monitor. #bingo it works!
