Is it safe to use my US iPhone/iPad charger with a simple European plug adapter? I'm using the US wall adapter that came with my iPhone to charge it:


When I travel to Europe, is it safe to use this with a simple US-European adapter, or do I need a transformer or some other device to step to the appropriate voltage/current? Do I risk frying my device?
Yes, you can use the simple adapter.  If you read the tiny fine print on the plug end you see "110-240V 50-60Hz" which means it will work on most common electrical systems around the world without a transformer.
