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?
Well, feeding voltage in that range to 24V fans would be fine, but “19 to 24V” makes it sound like a USB type-C charger or something which communicates with the device to set its output voltage. A power supply should have a single voltage.
Unless it’s one of those generic power supplies with a switch to set the voltage?
It’s just a universal laptop charger. Should I get a regular power supply?
If it just puts out normal voltage it’ll be fine.
I’d buy a cheap multimeter and test it for myself
