Hi all, I have a water pump connected to an adapter (pictured) but I am having trouble getting it to run using any of the cords I had on hand; it calls for using DC-only & 12V (between 9-14). I have tried Googling around & browsing Amazon but I'm a bit overwhelmed with options. Can anyone suggest an adapter that'll get this little guy pumping? Please forgive my naivety & TIA.

Also, I hope that it's kosher I ask here. If it's not, please let me know if there's a better place. Thanks again.

Since the pump doesn't seem to mention it does the pump packaging/paperwork mention how many amps it draws?

Edit I found it. Load current < 350mA

I would think damn near any 12v DC "wall wart" would do it, but the adapter you have may not be the right size for what you have laying around.

Could grab something like THIS that comes with its own adapter.

Thanks- I got the thing running through a breadboard power adapter of all things, to confirm the pump was still living, so I will try what you linked! I am beginning to wonder if I wired my last adapters’ poles. So, this might have been user error on my part, doh!

no worries, something like this would be fine

a 12v 1A power supply is sufficiently basic of a component that i wouldn't worry too much about like getting a higher-quality one or whatever they'll all probably work fine
