“I find myself traveling a lot and sometimes I don’t have access to a wall socket to charge my laptop. How do I charge my laptop from my car?”
If you want to use anything electrical in your car you will need something called an “inverter”. Inverters converts your vehicles 12-volt DC power to 120-AC power so you can use any small electrical items such as charging your laptop in the car. Sorry no fridges or oven, and don’t expect to run your 50 inch HDTV.
Car inverters plug into your car’s cigarette lighter to give you the three prongs for plugging in your laptop. You can buy inverter with more than one set of plugs as well to plug in multiple items some even have USB which is awesome for charging iPods, iPhone, or Blackberry.
This Duracell offers 1 AC plug and a USB port and comes in a small compact size for about 32 bucks.
The Xantrex Technologies is the most popular and highest rated car inverter from Amazon that offers two AC plugs but no USB. Offers 400 watt power which is enough to run most small electrical gadgets and gizmos.
