It is indeed possible to charge your laptop in your car or truck, but you do need a piece of special equipment to complete this task. Your vehicle also must have a working cigarette lighter, which is usually near the car stereo area. Once you obtain the appropriate adapter for your laptop, charging the computer with your running motor vehicle is a simple task. Keep in mind you won't be able to charge your laptop if the car's engine isn't running.


Step 1

Ensure you have the necessary adapter to charge your laptop with your car. You usually remove the power cord portion of your existing AC adapter and replace it with a DC cord that can fit into a car cigarette lighter socket.

If you don't have such an adapter, you can purchase one at your local electronics store or online at sites such as Amazon or Best Buy. You might want to purchase a universal laptop car charger. If you buy a model-specific adapter be sure your type of laptop is compatible.


Step 2

Plug the computer end of the adapter into your laptop as usual.

Step 3

Place the laptop onto a secure location to avoid damage to your computer. You may want to place it onto an unoccupied front passenger seat.



Step 4

Plug the DC end of the charger into your vehicle's cigarette lighter, just as you would with a car cellular phone adapter. This replaces your customary step of plugging the laptop into a traditional wall socket for charging. After you start your engine you might see a light indicating the laptop is being charged, depending on which model adapter you purchased.
