What Is This Plug?

Three questions about the thing in your hand, and we'll narrow 119 connectors down to the one it is. Skip anything you're not sure about — it still works, you just end up with two or three to choose between instead of one.

Still could be

119connectors

Answer a question to start narrowing it down.

1 · Where did you find it?
2 · What shape is it?
3 · What do the contacts look like?

Look at the end you're holding — the plug, the card, or the connector on the lead — not the socket it goes into.

Still stuck?

Send a photo of it straight to your store. Naming mystery connectors is a daily job at the counter, and we can tell you whether the lead you need is on the shelf before you drive in.

Down to a few? Turn this on and hold the plug against the screen.

Why There's No "Upload a Photo" Button

We looked at it properly. The problem isn't the cost — it's that a photo of the back of a computer has six connectors in it and no way of knowing which one you meant, and a confident wrong answer sends you out to buy the wrong cable. Some of these genuinely cannot be told apart from a photograph at all: the two commonest barrel plugs differ by four tenths of a millimetre, on the inside.

Three questions and a drawing you can hold the plug against gets you there without guessing — and it works with the internet playing up, which is sometimes exactly when you're hunting for a network cable.
