A voltage transformer is a device used for converting electrical output from either 220 volts to 110 volts or from 110 volts to 220 volts. It is an essential tool that allows you to safely use your kitchen appliances, entertainment systems, and other electronic devices. You will specifically find this tool handy when traveling to foreign countries that have lower or higher electronic outputs than what your device needs. In case you need to buy a voltage transformer, here are the things that you must take into consideration.
Step-Down or Step-Up
A step-down transformer is used when converting a 220-volt electronic output to power up a 110-volt device. On the other hand, a step-up transformer is used for converting a 110-volt electric output to charge a 220-volt device. To determine what type of transformer you will need, research about the power voltage of the countries you will visit. You can simply refer to a global voltage guide. You should also know the voltage requirement of the devices you will be carrying. Some models are called step-up and down transformers, combining two functions in one tool. If you are unsure which one to purchase, then opt for this type.
The size or the wattage of your voltage transformer depends on the total wattage of all devices you use. As a general rule, transformers should be twice or thrice higher than the wattage of your appliance because power tools tend to require more power when turned on. This is also necessary for your devices to properly and safely function. The size options you will see on the market range from 50 watts to 20,000 watts.
If you are a frequent traveler, you might want to purchase a voltage stabilizer. This tool is used in areas where power fluctuations called brownouts often happen. A voltage stabilizer protects your gadgets and appliances from getting damaged due to a sudden surge of power.
