Corded power adapter?

[drgoodwrench]

For those times when a battery is not needed? plugs into a car cigarette lighter or maybe even a 110 version? I use corded tools when power is available... and when not, I use my DeWalt!!! Just an Idea...

I would love to have this for when all my batteries are dead I would plug in my battery powered tool to an outlet or i know i'm going to use a lot of power that would drain a battery quick but don't want to buy a corded tool. I don't think the 12 V (car) chargers charge as well as the 110 V. I am excited for the new grease gun!
