-Using a DC adapter for your laptop rather than an [[electrical:inverter|inverter]] + the original 110v charger can save 10% or more power that would otherwise be lost in the inversion process.
+Using a DC adapter for your laptop rather than an [[electrical:inverter|inverter]] + the original 110v charger can save 10%-20% or more power that would otherwise be lost in the inversion process.  Most DC adapters will come with the ciggy port plug; it is common to cut the plug off and and wire it to the fuse box or to your preferred connector type.
-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.

 Dell sells a 12v power supply for their older/larger laptops that is much less bulky than generics: [[https://www.dell.com/en-us/shop/dell-auto-air-adapter-90w/apd/450-aelt/pc-accessories|Dell 12v Auto/Air DC Power Adapter]].

-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]].

This is only realistically needed for the largest/heaviest laptops, especially gaming laptops or engineering/creator-oriented laptops.
