DIY 9V DC to 110V AC inverter, and/or 9V DC to 19V DC transformer? Answered

Hi, I want to build a 9V/110V DC/AC inverter, so I can power up things like my laptop with a car lighter socket. It would be always nice to be able to use electronics in the car when I'm traveling...
What kind of components will I need and how would the schematic looks like? If DC/AC is a hard task, how would I go about building a 9V/19V DC/DC transformer so I can at least power up my laptop on the go?

you can build a 60Hz oscillator then amplify the current then use a transformer

you can use a 50VA 110v to 9v in reverse as transformers can be also used reverse but be careful about the current draw

50VA (almost)= 50W

The car will be 12V, where is 9V coming from?
(It's cheaper and easier to buy an inverter)

FROM 12V CAR BATTERY. AND USE A 75 OHM RESISTOR

Why not build a 12V?110V DC/AC adapter then?
