Users say:
This product is a great tool for controlling an electric fan, with a voltage knob that is easy to use and adjust. It is rated at 3 amps, but is suitable for smaller units. The manual is a complete joke, and the fan motor is not grounded properly. However, it is worth the money and can be adjusted to bring the fan up to desired temperature.
This variable transformer is a great device for quality control testing, equipment testing on low and high voltage, control over heat, speed, and more. In order to purchase the right variable transformer, it is critical that you know the amp usage by your electronic device. It is always best to be conservative otherwise you risk destroying the variable transformer and it can be very dangerous. Most devices have a surge amperage (when first turned on) that is much higher than the device's operating amp rating. For example, if your device requires 3 amp, buy the variable transformer with up to 5 amp to account for the surge amperage. A …

Most devices have a surge amperage (when first turned on) that is much higher than the device's operating amp rating. For example, if your device requires 3 amp, buy the variable transformer with up to 5 amp to account for the surge amperage. A rating of 300VA means that at 100volt, the unit can sustain at maximum 3amp. If at 120 volt the unit can sustain at 2.5amp. Note - Indoor use only. Do not operate in a condition that may cause electrocution and fire. Do not operate in a wet environment. Do not operate near flammable substance.
