What are you trying to convert??

Laptop computers tend to come with powersupplies that don't need converters. All you need as a plug to put on the end of the powercable to fit the euro plugs. Check the powerbrick to see if it says 110-230 volts (most do). Easiest way to buy the plug is at the airport. Another way is to buy the whole cable in germany (harder to do). Radioshack used to carry these but don't know about these days.

Portable DVD player? Runs on batts? Cell phone, make sure it works to begin with (might be pricy). Or buy a quadband gsm phone (cheap on ebay) and then over in germany a prepaid sim card to put into the phone The t mobile ones work great. Check the phone charger again for 120-230 volts. Mine work, I got 2 cheap phones for germany, chargers work fine, I had one in hospital and my wife had the other phone. They do make some actual little electronic converter thingies but me travelling over there all the time never need them. One place to try might be amazon.com or at the airport.

Tell me what you have and I can figure it out.
