If your a DeWalt user like me, you'll love this charger. The fact that you have another charger on the jobsite is reason enough to buy one. But since  this charger can crank out the tunes makes it that much better. It plays  off of DeWalt batteries so you don't have to worry about extension cords.  You can also hook up a Discman to it. The only downfall for me is the range  of the antennae. It would be nice if I could pick up more stations. Other  than that, it rocks
