I bought this so I could carry it with me and recharge my Nook when I am out and about. It works very well for that. The prongs of the charger fold down, so they don't tear holes in my bag or anything in the same pocket with it. The charging cable is plenty long enough to reach the outlet at my local coffee shop. It's an official product, so I don't have any worries about it overheating my Nook and causing a fire like knockoff brands can. And if anything happens to my everyday charger, I know I have a spare.
