Dell just came out with their own AC/air/auto power supply for the D600. I just purchased one and can confirm that it will charge the battery--at least using 110 volts. It is larger and heavier than the IGO juice, but it does use the juice peripheral power cords for cell phones and handheld devices. I was pretty bummed out when I bought the Targus version of this and power tip 103. I found out the hard way on a 1 week business trip that my battery was not charging--what a hassle to have a completely dead battery.

Dell Part# 310-4804
