Voltage Converters & Transformers

A transformer is a device that adjusts the voltage when the voltage at the site does not match the usable voltage of the tools on hand. The main products can convert the voltage from 100V to 200V, and there are even transformers that have a step-up function from 100V to 200V and a step-down function from 200V to 100V. Includes a high-performance transformer with a single step-up / step-down function. Using a booster that raises the voltage can eliminate the voltage drop caused by the voltage drop when using an extension cord.
