In order to connect you need the right plug with the right polarity at the right volt and the right amp settings.

I do have drawers that are filled with Ac adapters that I have accumulated but seldom does one match a gadget I find. I am not sure how that can be, but that is my life.

Right now I have a bit of a different problem. I am trying to troubleshoot an audio mixer. One possibility is that the existing battery adapter is not working correctly.

Ideally I would reach into my collection, pull out a replacement and be good to go. Not one of the other ones I have match plug or power configuration.

This is bugging the hell out of me, and I know I am not the only person with this issue. I do have friend with their own drawer and their own collection of things that is of no use until you can turn then on.

Buying replacement ac adapters, when that is possible, is usually extremely expensive. Sometimes you can buy them real cheap on eBay, and usually those work for a while.

I do have multi voltage ad adapters that come with some tips. Usually they cannot be configured or tipped to what I need.

In my research I found “lab” power supplies like this one:

This thing looks awesome. It can set to nearly all my required power configuration. Score.

Except.

How do I get that power into my gadgets? There is no option for buying a bag of 1000 tips.

The wires it comes with do not look at all helpful.

What is the solution to the plague of missing ac adapters? Someone must have figured this out?

If not, it might be something I can invest a lot of effort it into for the sake of all humanity.
