Is it safe to use a laptop charger to power two parallel 24v fans?

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...

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.

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.
