What is a Voltage Converter?

A voltage converter is an electrical device that changes the voltage of an electric power source to match the voltage requirements of the device you want to use.

Two main types:

1. Step-Up Converter: Increases voltage (e.g., 110V ➜ 220V)

2. Step-Down Converter: Decreases voltage (e.g., 220V ➜ 110V)

Common Use Case:

When you travel internationally and need to plug your 110V U.S. device into a 220V European outleta voltage converter prevents your device from frying or malfunctioning.

Some converters also include plug adapters, but those only change the shape of the plug, not the voltage—important distinction!

Features of a Voltage Converter Tool

• Converts 110V to 220V or vice versa, allowing safe use of appliances across different countries.
• Often includes different plug types or multiple outlets to support various devices at once.
• Some models auto-detect input voltage, others require you to manually switch between 110V and 220V.
• Protects devices from voltage spikes, short circuits, and overheating.
• Supports a specific range of wattage (e.g., 50W to 2000W); crucial for determining what appliances it can handle (e.g., phone chargers vs. hair dryers).
• Especially for travel models, they’re made lightweight and easy to pack.
• LED indicators show power status; some units include built-in fans for temperature regulation.

Units of Voltage Measurement

1. Centimetre–Gram–Second Units

Older scientific systems sometimes use Centimetre–Gram–Second Units. Our converter supports them.

2. Voltage Unit

The voltage unit typically used is the volt (V), but conversions to millivolts (mV) and kilovolts (kV) are often required.

3. Unit

Understanding the correct unit is key to accurate calculations. This tool handles each one effortlessly.
