You cannot simply plug a euro power cable into our outlets here. Physically impossible. Plus, it wouldn't matter. They step down 220v - we only step down 110v. Real problem would be plugging an American power supply into a European outlet. Get a North American power supply for the CD32 and a compatible monitor/TV to play with the PAL chipset. Our standard is NTSC. If you purchase a PAL CD32, you can try to force it into NTSC by plugging an Amiga mouse in and holding down both buttons upon startup and selecting the screen mode.
Using it with a PAL compatible Amiga monitor or TV would be your best bet though. Many of the games in circulation are going to be PAL anyway...
