Can I use my AC adaptor in the car?

Most AC adaptors run on 110/220V alternating current, while the electrical power on the car is about 12V direct current. A typical Dell Latitude laptop uses a 19V charger. The only way to charge your Dell laptop in such a situation is getting a device that will convert the voltage to a 19/20V current that can charge your laptop. There are two devices that can help you with this, an in-car adapter charger or a power inverter.

This is a device that plugs into the cigarette socket and converts the 12V current into a current that your AC charger can draw from. It usually has a normal wall socket at the other end, where you can plug-in. The inverter may place a huge strain on your battery or mess with the wiring system. Always observe extra caution when shopping for these devices.

Important tips when using in-car laptop chargers

  • Standard laptop car chargers plug into the cigarette lighter socket in your car. Make sure that you have a working socket.
  • Place the laptop in a place where it cannot get trampled on or damaged easily. The front passenger seat might work just fine when unoccupied.
  • The chargers drain a lot of power from the battery. You should only plug them in while the engine is running. Some chargers may stop working or beep once your battery power drops below the 10/12V threshold.
