Can you charge a laptop in a car?

Most of you might surprise, is it even possible to charge a laptop in a car?

Short Answer, Yes!

Long answer, it includes a bit bit of science.

The car that you use comes with a 12V Power Outlet (also known as cigarette Lighter), that with the help of a car Adapter will be used to power your smartphone and tablets.

However, the 12V Power Outlet, because the name suggests, provides only 12V of DC (Direct Current) power. Whereas your laptop needs 110/220V AC (Alternating Current) to charge itself via the charger.

Hence you will need a power inverter to convert DC to AC, and with that, you will charge your laptop easily in your car.
