Can I charge my Ipad in europe without using a voltage converter?

No voltage converter required. The iPad charger is auto-sensing and will work with voltages from 120-240 VAC

Just need a plug adapter. ANd it doesn't have to be the apple one, you can get one from any major retailer, walmart, walgreens, target, etc. Look in the luggage section

Also works on 50-60Hz power.

Just spent 10 days in Ireland with our recently-purchased iPad and had no trouble charging it with the proper adaptor. NOTE: The UK uses a different adapter than continental Europe. Make sure you have the right adaptor for the counties you will visit. This article is helpful:
