How do I go about doing this? I sync my iPod with my iMac, but I'm leaving this weekend, and due to a freak accident, I no longer have my 12V iPod charger, so I'm going to carry my ibook along. I'm afraid to plug it in because I don't want to sync anything, I just want to charge it.

As part of Apple's anti-piracy measures, an iPod will only sync with one Mac. So you can plug it in and it won't sync.
If you want to be extra sure, just set iTunes on that computer to manual updating.

When you plug into the new computer you should get a dialogue box that asks if you want to sync with this Mac, and you just click "no." That's how mine works; I use it to carry files between home and work and I don't sync to the work Mac.
