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
you will probably have a new battery charger purchase in your future.
When equipment is run at a lower voltage than it is designed for, it does not operate correctly. A light will glow dimly or not at all, a heater produces much less heat. Electronic equipment may not function at all.
First, someone would have changed the plug before that would be possible. 240 Volt receptacles do not accept 120 Volt plugs. Second, IF someone changed the plug on the compressor, then plugged it in using both legs of the 240 Volt circuit, the compressor motor would self destruct instantly; internal wiring would burn and you would smell the burning insulation.
Yes.
No, the battery charger has to match the voltage of the battery it is to charge.
Possibly but not likely. If it has an internal fuse it can be fixed. If not then it is more than likely ruined.
It should be ok
temporary it blows or KABOOOMM....
A bright flash and a dud bulb, possibly a blown fuse instead.
There is no remedy but to plug it into a 230 circut.
No, but it really is not suggested.
zzzzzzzzzzzAAAAAAAAAAAAAAAPPPPPPPPPP !!!!!

You will destroy the battery and be buying a new one.
The battery will attempt to charge the charger since the battery is at a higher voltage than the charger. Thus, the battery will simply discharge and generate heat. If you leave it plugged in long enough, eventually the battery will discharge to a point where it can maintain only 6V, where it will stay until you actually charge the battery.
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
If you buy the 220 Volt Adapter for the XL it will work fine. If you just plug it in the resistors and hardware within the charger will short out and be unuseable after that. I purchased the 220 Volt adapter for the DSI XL for less that $10.00 from Amazon and it worked fine.
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the battery.
