Yes, all wall receptacles are rated at 125 or 130 volts.
Yes you can safely do this. Most appliances that are marked 115 volts will operate on outlet between 110 and 120 volts safely.
It is not recommended to plug a 110v hair straightener into a 220v outlet as it may damage the appliance and pose a safety hazard. You should use a voltage converter or transformer to safely use the hair straightener with the higher voltage outlet.
No.
No. the plug configuration is different, just for that reason so that the two voltages can not be crossed over.
Yes
Should be ok provided you do not draw too much current.
No, it is not safe to use a 115V unit in a 230V plug as it may damage the appliance or cause a safety hazard. It is important to match the voltage requirements of the appliance with the power supply to avoid any damage or potential accidents.
You cannot directly plug a 110v device into a 220v outlet. This can cause damage to the device or even create a safety hazard. You would need a voltage converter or transformer to safely convert the 220v outlet to the appropriate voltage for the 110v device.
No, the plug and socket are incompatible, and even if you changed the plug, the unit would not operate on such alow voltage.
no
Yes, it uses an AC power adapter.
No, it is not safe to plug a 110v device into a 220v outlet as it can cause damage to the device and pose a risk of fire or electrical hazards. It is important to match the voltage requirements of the device with the outlet to ensure safety.
