-Almost all small-to-medium modern laptops run off USB-C, which is commonly rated for up to 90w;  a [[https://www.amazon.com/Charger-HKY-12V-24V-Adapter-Replacement/dp/B08MQ7HMPY/|12v USB-C adapter]] will plug into a 12v cigarette lighter port and give up to 90w of USB-C which will power most laptops. For a bit more money you can buy an OEM((Original Equipment Manufacturer)) car charger.

-For larger/newer laptops (made from late-2023), USB-C has been expanded to support 140w of power delivery((Technically refered to as USB-C PD 1.4)). This is too much for a [[electrical:12v:ports|cigarette lighter]] outlet((they're only rated for 10amps, which works out to 120w)), but [[https://www.usbgear.com/cg-pd140epr.html|direct-wire DC power supplies will give you a 140w capable USB-C port]].
