100v2 - 220v + 121 = (10v - 11)2
There will be no problems as the Mac laptops are designed to work internationally with a line voltage ranging from 100V to 240V.

Do you mean a 220V as in a power in Europe? Then,Check your adaptor. It will tell you the input voltage. If it sates that the range of the input voltage in 100V-240V then YES you can plug in your adapter into a 220V outlet.Please note that some people advise that you plug in the adapter into the power before plugging it into the computer.
After the smoke clears...... the charger won't work. Unless it was rated for 120v-220v. Radio Shack (and others) sell devices to convert 220v to 110v to use your charger, but be sure to get one that uses a "transformer". Here's one rated for 85w (watts) http://www.radioshack.com/product/index.jsp?productId=2062422
No, a dimmer pack will not convert the voltage. It simply controls the amount of power (voltage) sent to the light fixture, allowing you to adjust the brightness. You need to ensure that the dimmer pack is compatible with the voltage of the light fixture. If your light fixture requires 220V, you should use a dimmer pack rated for 220V.
Buy a power inverter. This will change your DC (car charger) to AC.
No, a device designed for 110v will not work on 220v without a voltage converter.
More than likely yes it will work just fine.
No, a device designed for 110v cannot work on 220v without a voltage converter.
No, by doubling the input voltage to the charger which is just a transformer you will be doubling the output of the charger. Batteries like to be charged at about a volt and a half above their working voltage.
