How much does this cost to the nearest dollar?

AC 4000W Variable Fan Speed Controller, AC Motor Speed Controller, Variable Voltage Regulator Adjustable Voltage Controller High Power Dimmer Controller
NOTE 1.Many motors do NOT support voltage regulation (for example, single-phase motors, dual-value capacitor motors, asynchronous motors, pumps, etc. are NOT supported.) motor-type equipment can only be adjusted 1) without the capacitor fan 2) power tools hand drill, angle grinder, electric screwdriver, etc. 2.The input voltage is then the output voltage is The input voltage is then the output voltage is So both 110v and 220v can be used as the input voltage, But both cannot work at the same time. And it Input alternating current, the output is also alternating current, not direct current. 3.This product
