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.
The power-bar must be plugged into the correct voltage it was designed for.
Yes, although you might have lucked out and tripped the breaker first.
Use a transformer to lower from 220 to 110V.
No
Do not do this.
No.
220v and 110v are almost the only voltages used around the world because they are the most efficient.
You have burned something out in either the control circuit or the motor itself.
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.
The fact that it's supposed to. Voltage is stated as the difference between the two wires carrying electricity to the load. When they bring power to the house from the utility, you get two wires carrying 110v but they're 180 degrees out of phase. Imagine one carries positive 110v and the other carries negative 110v. If you hook one of these wires plus a neutral (zero volts) to the load, you get 110v--110v over 0v. If you hook both of them to the load, you get positive 110v over negative 110v, or 220v. So...red to white is 110v, black to white is 110v, red to black is 220v.
The breaker will blow because you are effectively causing a short circuit.
yes, but you need a transformer to convert it,
