I have a 3D printer and have a special filter that has two 24V blower fans that are connected in parallel. Unfortunately my printer doesn’t have the proper connectors for the fans. So if I purchase something like this power jack adapter I know the adapter is 12V not sure if that would make a difference. Anyway if I connect the female part of that adapter to the fan cables and plug in my laptop charger which is rated for 19v to 24V would that be ok?

If those adapters are fine, should I just purchase 12V blower fans instead?

    Just get a boost converter. Cheap, like < $20. Your only worry would be amps, but fans can’t draw enough to really concern yourself.

        I figured you already had some type of adapter already. Either the one you linked, or the DC connection from the printer. If that’s the case, then it’s ridiculously easy to do a DC to DC adapter. If you do not have a DC supply and just need a 24v power supply, splurge on something like this.

          I just have my laptop one which I don;'t want to splice because well I use it for my laptop too lol

          Would I be better off with that type of power supply?

            Honestly you’d probably be fine with your original idea. But, that means you can’t charge your laptop while printing and, the 24v power supply I linked to is cheaper than your original idea.
