I was stationed at Bitburg Air Base in Germany during my stint in the Air Force. It was the trip to Europe I would otherwise never afford on my own.

We stayed in dorms that were wired with 220V schuko outlets, no 120 as far as I know. I had a step down transformer to run my dedicated 115V electronics, but most of it had a dual voltage switch.

No mishaps with 220 except the one time I didn't know what an immersion cup warmer was.

I plugged it in and went to fill the cup...came back and the coil had burned wide open.
