Looking for a car USB charger to charge a laptop through USB-C, the power brick that comes with the laptop says "Max 65W", on the back of the laptop says "20V 3.25A" which is exactly 65W.
This one look ok (65W)? $32 after discount:
Or the more powerful one (100W)? About the same $32 after discount:
Higher power is good for future proofing, but not sure if it draws more power and causes more heat. Or the same if laptop doesn't require more power.
I'd be worried about draining the car battery.
Can't really comment on the chargers but amazon is pretty good for returns if it doesn't met your requirements. I'd personally get a small wall adapter (I'm using the nintendo switch charger for the work laptop) or PD capable power bank.
