What kind of plugs and sockets do you have?

220V to 110V (plug and socket illustration); 220V to 100V (illustration of plug and socket); 110V to 220V (plug and socket illustration);

If I don't use the voltage converter, can the 110V electrical appliances be plugged into the 220V socket?

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.

If the input voltage is 220 volts/50 hertz, can it produce 110 volts/60 hertz?

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 voltage converter can be connected to more than one electrical appliances to use?

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.

Voltage converter with frequency conversion function?

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

How Shunhong’s Thermal Protection Prevents Overheating

Thermal protection is a critical safety feature in voltage converters that prevents catastrophic overheating during high-power usage.

Shunhong Transformer, a trusted brand with over 30 years of expertise, integrates advanced thermal monitoring into its products to safeguard both the device and connected electronics.

If the internal temperature reaches 85℃ due to prolonged overload, the system automatically shuts off the power.

Unlike traditional fuses, this smart protection resets once the unit cools down, offering reusable, reliable safety for daily use.
