Cigarette lighter fuse

I have a 1999 Isuzu Rodeo LSE. My cigarette lighter fuse keeps blowing about every 3-5 days. I just keep replacing it and then it happens again. I was just wondering if anyone had any ideas what could be causing this or if they encountered this before.

your cell phone charger

Acutally I do not use a car cell phone charger. I use my cigarette lighter just when I am having a cigarette, which is about twice a day in my car.

you may try replacing the element they sometimes short and cause the fuse to blow

This may help. I would check to make sure there wasn't a circuit breaker instead of a fuse for the lighter. Looks just like an ordinary fuse but is really a circuit breaker. Or try replacing it with one. When it gets too hot it will open but will work again and again.
