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.

no worries, something like this would be fine

https://www.amazon.com/JOVNO-100-240V-Converter-Transformer-5-5x2-5mm/dp/B0875WMYCX

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

I personally wouldn't put any unbranded and uncertified AC to DC converter in my home. Without proper regulatory testing and certification it's a fire hazard.

you know, I saw the CE mark on the label, but oddly enough on closer inspection it appears to be like a knockoff? i hadn't heard of this before but apparently when they're close together like that it actually stands for China Export which (unlike the real CE) has no safety standards associated

this is actually pretty egregious and I'm not sure how they're getting away with it lol but anyways I appreciate the call out, learned something today

Afaik that's a myth. There is no testing or certification associated with the CE logo, it's just a self-declaration of the manufacturer that certain standards are met. You can just buy rolls of these stickers, or print them yourselves. That's what manufacturers do, legit ones and shitty ones.

Legit companies won't just print it without self testing. At any point the EU can demand test data and if you don't have it they can block your company from shipping there. It also opens the company up to lawsuits. Big companies with a brand to protect won't mess around with this, it's cheaper to design and test.
