Power and Control PC fans with Cigarette Lighter

[nrgcreator]

Hello, I'm looking to make a window exhaust fan using PC fans to use when I sleep in my van. I need some advice on how to control and power the fans. I have 4 fans I will mount to ABS that will fit in the drivers window. I will power it by using a Jackery power station. The preferred power cable should have a 12v cigarette plug so I can use it in the power station or directly in the van should the need arise. Main question is regarding which PWM DC Motor Speed Controller Switch i should pick up? There are so many different options with different power ratings. The fans have a 4-pin PWM connection and 12 Volts, 2.4 watts each (x4). Can someone please advise me on what controller switch and what power supply I need to use? I know nothing about this kind of thing so I'm looking for advice before pulling the trigger. Links to the components I was considering are below in the comments. Thank you.

I wouldn't bother with a speed controller, just pick fans with the desired airflow vs noise trade off, but if you want one, why not just use one meant for a PC to power PC fans? For example:

There are also some with a 3.5" or 5.25" bay mounting for case front bays if this makes it more convenient to mount on the dash or another panel.

Will the battery in the van survive being discharged all night by a fan? The next morning maybe the van engine will not start.

^ I assume he's going to use the linked $500 Li-Ion power pack... at full throttle, 12V input, the fans are rated for 0.2A but depending on how they rate, it might be a peak and avg current is a fair bit lower, but using that #, x4 fans, say 8 hrs a night = 6.4Ah.
