When your car engine is running and you plug a GPS or such into your cigarette lighter or adapter does the power run directly off of your car battery? I know that happens when your car engine is not running, the power comes from your battery, but I always thought that when your car engine is running, everything runs off the power your engine generates.
However this past week on Clark Howard I he said he was wondering why he would always buy the better car batteries, and they would only last less than a year. He said he had his car checked and everything was fine. So they told him that everything he plugs into his adapters (GPS, Ipod,etc.) is what is running his battery down as even when the car running they pull power from the car battery, NOT the engine. So he went and got a portable battery pack that he uses instead of plugging everything in.
So is he right?
