A No. 220V is a high voltage supply compared to 110V. Once turned on, it will quickly damage your appliances. It is recommended that you purchase a step-down power converter suitable for your own appliances to avoid damaging them. We recommend that you purchase a step-down power adapter that is suitable for your own appliances to avoid damage to your appliances.

A Cannot. Voltage converters can only convert 110V to 220V, they cannot change the frequency.
This voltage converter is rated at 50Hz/60Hz and is compatible with most countries.
However, if the appliance frequency is not the same as the local frequency, it may not work. For example, if a British appliance to be used in the United States has a rated frequency of For example, if a British appliance to be used in the United States is rated at 50Hz and the local frequency in the United States is rated at 60Hz, the appliance may not work because of the difference in frequency.

A Check the power of all devices and calculate the total power to be consumed when used simultaneously.
The total power of the voltage converter should exceed the total power of the equipment by 30% or more for normal use.

A The voltage converter is compatible for use with 50Hz and 60Hz frequency appliances, but cannot change an appliance's rated 50Hz frequency to 60Hz.

A When the product is used, it is recommended that it not be used near flammable and explosive items, and not be used in a water source.

A Voltage converter normal operation, due to the alternating magnetic flux caused by the iron core vibration, and issued a uniform humming sound, this is a normal phenomenon, generally does not affect the use of This is a normal phenomenon and generally does not affect the use.

A Yes. If you have electrical appliances with heating function, such as heater, hot pot, electric blanket and other electrical appliances, please do not buy the voltage converter according to the regular parameters of the Voltage converter. It is recommended to purchase a voltage converter with two or more times the power of the appliance.

A YES. If you have appliances with motors, such as air conditioners, refrigerators and other appliances, please do not purchase a voltage converter according to the regular parameters. The operating power and starting current of the motor are relatively large and need to be buffered. The running power and starting current of the motor are relatively large, and need to be buffered, so it is recommended to purchase a transformer power of 2 times or more of the power of the appliance to use with it.

A The number of watts required to power an appliance can be calculated from the amperage indicated on the appliance label.
The formula is: Watts = Voltage x Amps (e.g. 120V x 10A = 1200W).
If a hair dryer is labeled with a voltage of 120V and a current of 10A, the wattage of the hair dryer will be 120V x 10A = 1200W.

A Generally electrical appliances are labeled with a marking of power in W or VA.

A Check the maximum power consumption information embodied in the label on the body of the appliance.
According to the principle of using voltage converter, Sun Red voltage converter suggests to reserve 30% space when using, so the required voltage converter power = Electrical power x 1.3.
For example, if the power of the appliance is 300W, the recommended minimum power of the voltage converter = 300W * 1.2 = 360W.

A In areas where the rated voltage is 100V, choose the 100V to 220V voltage converter when you need to use 220V appliances;
In areas where the rated voltage is 110V, choose the 110V to 220V voltage converter when you need to use 220V appliances;
In areas where the rated voltage is 220V, choose the 220V to 110V voltage converter when you need to use 110V appliances;
In areas where the rated voltage is 220V, choose the 220V to 100V voltage converter when you need to use 100V appliances.

A 220V to 110V transformer is used in countries or regions where the rated voltage is 220V to use electrical appliances rated 110V, it is necessary to convert the local standard voltage 220V to 110V, in order to support the normal use of 110V appliances.

A The first step is to determine what the rated voltage is in the country of manufacture of the appliance to be used, and then to choose the value of the rated voltage in the country of manufacture of the appliance by converting the voltage in the home country to the rated voltage in the country of manufacture. Voltage value can be. For example, the U.S. voltage standard is 110V, to use European appliances in the U.S. you need to convert 110V to 220V.
Therefore, you need to choose a 110V to 220V voltage converter model. If you want to use American appliances rated at 110V in China, you need to buy a 220V to 220V converter. If you want to use 110V rated American appliances in 220V rated China, you need to buy a 220V to 110V converter model.

A Choose a 220V to 110V voltage converter. The rated voltage of most European countries is around 230V, while the rated voltage of American electrical appliances is 110V. Therefore, appliances made in the U.S.A. cannot be directly connected to the European power supply, but need to use a power supply voltage converter to convert the European 230V voltage to 110V before they can be used in Europe. It is necessary to use a power supply voltage converter to convert the European 230V voltage to 110V voltage to support the use of U.S.-made appliances in Europe. The voltage converter produced by Sun Hung is compatible with the input range of 220V~240V. is 220V~240V, so the European 230V voltage can be converted normally.

A The standard model is 220V to 110V, 220V to 100V, 110V to 220V;
