Charging w/ old Firewire power supply

Hey Folks,

I'm looking at buying one of the new iPods... can I use my old plug-in-the-wall power supply and firewire cable to charge it, or do I have to buy a new one?

I've got both an IPod Mini and a 4G 20Gb clickwheel --> both came with power adapters.

Thanks!

Rocky
