The fan is rated at 12V 0.3A, do you think a charging module that could do 12V 1.5A output will work?

I have a stupid idea of cooling my phone with a M.2 active cooling heat sink and the fan is rated at 12V 0.3A. Then, When I was searching for a charger for my brother because he lost his when he was on vacation and I saw the 18w charger could do 12v 1.5a. Do you think the charger could power the fan through a Qualcomm quick charge or Power delivery 3.0 Type-C module?

Yes and no.

The fan's nominal voltage (the voltage the fan is 'most happy' at) is 12v but will work at lower voltages, but making the fan spin slower.

The 0.3A is the current, how much current the fan will take from the power source. If you power it  with a power supply that can supply 10A of current, the fan will still take only 0.3A

 

Anyway... the charger can output UP TO 12v, but something needs to tell the charger to bump up the voltage from the default 5v to 12v ... by default, the charger needs to output 5v for safety just in case you plug other things in it. There must be "some brains" (in your phone the battery management chip) to tell the charger to increase voltage to 12v.

 

If you connect the fan directly to the charger, the charger will give the fan 5v, and depending on the fan it may start and spin but at very slow speed.

It's not stupid if it works, but as above. Yet....

 

YOU ARE PLAYING WITH HIGH-ENOUGH WATTAGE TO MAKE SOME SPARKS, SMOKES OR EVEN *POOF* ON YOUR ELECTRONICS. You have been warned, so do it at your own risk. I suggest to always test it on USB tester/else before you even plug it in onto your phone.

 

You could design some power conversion circuit like so.

See below for more details about the PD/QC trigger board. When you wanna get it, just pick whether protocol (PD/QC) you use on the marketplace.

 

 

As for the power that will go to the phone, what's the phone you use? Refer to the maximum charging voltage-current that it supports. Depending on your phone, it might support either 5/9V instead of 12V.

 

It'd be a lot safer to use separate power supply tbh, as fans can sometimes take inconsistent wattage, which both your power brick and phone won't like much.

Humor me, as you should do.

Oh, I wont be charging the phone along with the fan but thanks for the lecture btw! Maybe my grammar isnt that that good.

Oh, you could simply use that PD/QC trigger board then, and you're good to go, even use the one with switch that you can change the speed by changing the voltage.

Nah, as long as the language's understandable anyway.

So a 12V power supply with is more preferable? I found this so i think it will work?
