I have a MacBook and a 30 GB iPod video. Obviously, the MacBook came with a wall charger but also an AC extension cord that plugs into a wall and then plugs back into the MacBook charger. Like so: However, I also have a USB wall charger for the iPod video. The thing can plug directly into an electrical outlet which then connects to the iPod via the USB/Dock connector cable. That's fine and dandy. Now I want to know if I can remove the prong part of the iPod USB wall charger and connect it to the MacBook's AC extension cord to charge the iPod without damaging it.
