Comment on Can I plug Nevermore filter where I circled?
FuglyDuck@lemmy.world 11 months agoPi’s are usually 5vs, they won’t drive a 24v fan happily at all.
At that point what you can do is a power relay- like how most bed heaters work. That could be controlled by a pi, but delivers power from a 24v source.

Like I said in my other comment
would it just be better for me to use one of these amazon.com/…/ref=ppx_yo_dt_b_asin_title_o00_s00?i… with a laptop charger?

If the charger is a 24v powesupply, that would work. I would also suggest getting a switch to put in line so you don’t have to keep unplugging it- either a rocker switch or mini toggle.

Not sure how familiar you are with electronic stuff, but the fans I have are 24v and 0.1A my laptop charger outputs up to 6A that shouldn’t be an issue right?

Volts need to match, nominally.
Your fans will only draw .1A from the supply- as long as your supply has enough amperage to supply everything running… your fine.
