Ok, for all of you go-getters who want to power their house from a cigarette lighter socket, I have news for you, good idea but not possible with an inverter. However, there are many things you can power with your cigarette lighter socket.
Anytime you want to power a device with your car battery, you’ll need to determine what device and for how long. If you want to power anything that is 1.5 amps (180 watts) or less you can use your cigarette lighter socket. If your power requirements are more than 180 watts, you’ll have to direct connect to your battery.
A few examples of items you can power with your cigarette lighter socket:
cell phone
handheld games
digital camera chargers
mp3 players
small warmers
small fan
laptop (1.5 amps or smaller)
