laptops definitely require specific chargers, even the USB C ones. most USB car chargers, including USB C ones, are good for things like phones, tablets, usb speakers, and so forth.
my favorite USB C car charger is the Anker PowerDrive III Duo, which has up to 36 watts of USB C "PD" pookah. These do 5V up to 2.4 amp (12W), 9V at 2A (18W), and 12V at 1.5A (also 18W), and auto sense so they work with a range of devices including the non-standard Qualcomm stuff. Both ports can deliver the full output levels, and each individual autosenses whats plugged into it.

this fast charges my Pixel 3a phone, my wife's Pixel 3a XL, my Huawei MediaPad M5 tablet, my JBL Charge 4 speaker. I also hard wired a dual USB "A" 2.1 amp charger in the trailer, which I use for things like USB lanterns that expect a USB A or use a cord with a USB Micro B connector... a A to C cord on a 5V 2A charger will charge my phone 'fast' but not 'rapidly'.
