The laptop has a power supply that connects between the laptop and the wall outlet. Looking at the power supply, the input voltage will show a working voltage from 100 to 240 volts. You may need a pin changing adapter because the pin configuration is different between 110 outlets and 220 volt outlets. Get past the pin configuration difference the computer will operate on both voltages through the power supply as long it is in the voltage range stated above.
NO, unless you get a converter that converts 220 to 110.
A 220 oulet line carries two 110 vold lines and a ground wire. The outlet is shaped differently than the standard household (110) outlet, usually having at least one (plug-in) prong 90 deg to the other, sometines two of the prongs. This type is usually found in a utility room for dryers, most of which use 220 power.
Yes, but you need a converter that changes 220 to 110, if you plug it into a 110 plug. Of course, if you plug it into a 220 outlet you don't need a converter, but in either case you will need a plug adapter.
220
I work At sears the highest BTU's we have is 15,000 that will use 110 outlet
A 220 outlet will have one neutral (white) and two hots (black and red normally) just use the neutral and just one of the two hot wires. Careful where you do this because normal 110 breakers are 15 or 20 amp and normally 220 breakers tend to be either 30 amp for a dryer or 50 amp for a stove.
No.
China uses 220 Volts AC for household electricity
Yes. 110 and 220 plugs are different so that you cannot plug a 110 recepticle into a 220 outlet and vice versa. If a home is wired for 220 it means that the potential is there for 220 recepticles. Your oven and clothes dryer require 220.
no
Use a step-up transformer from 110 volts to 220 volts. Try getting one at Home Depot or SEARS.
Some appliances may work, but I imagine most would either blow a fuse or just burn out. Definately not advised unless you use a transformer. With the right transformer everything should work fine.
