read the label on your charger
if it says 90v to 250V it will be ok
it it says 120V it will not be ok
Dubai uses 220 VAC at 50 Hz (in the USA, we use 120 VAC at 60 Hz). They also use the G type plug.
No, you cannot directly get 220 volts from a 120-volt outlet. You would need a transformer or voltage converter to step up the voltage. Make sure to use the appropriate equipment to avoid damaging your devices or creating a safety hazard.
Nominal residential voltage is 120/240 volts. Not sure from you description if the plug is just rated at 230 volts or is supplying 230 volts (It is likely that the plug may be rated at 230 volts, but only operating at 120 volts). A typical hand held hair dryer would operate on 120 volts. A commercial hair dryer might operate at 220 volts, but must be plugged into a 220 supply.
110-120 Volts BUT IN SOME AREAS 220.
Mexico has 110 to 120 volts. SOME AREAS 220.
In the USA it is usually 120/208 or 120/240 volts In Europe I think it's 220 volts
If the supply voltage is Vs and the equipment voltage is Va, then the equipment will work if Va = Vs (equation). But if Vs / Va = 220 / 120 (equation) the equipment will fail.
No, the source voltage can not change to a lower voltage without using equipment to do so.
No, in North America the plug configuration will not allow that to happen. The blade configuration for 120 volts are in parallel where as the 220 volt configuration are in tandem.
No, it is not safe to plug a 220 volt heat pad bought in China into a US 120 volt outlet. The voltage difference can damage the heat pad and pose a safety risk. You would need a transformer or voltage converter to safely use the heat pad in the US.
The local current is 220 volts and ground connection is made by a 2 pin plug.
There is no remedy but to plug it into a 230 circut.
