The measured output voltage of an airplane is a virtual voltage and the correct output voltage can only be measured by connecting a load of more than 20W.2. Input AC output AC not DC.3. The 4000W mentioned above refers to the limit power when working under resistive load. The inductive load is third of the resistive load.Resistive load refers to tungsten filament lamp heating wire etc. Inductive load refers to series excitation motor etc. Circuit board electronic products are carefully used.4. The shell of this product is made of PC/PP flame retardant material.Please be sure to read the product instructions before use follow the steps!The electronic pressure regulator is used in the form of a hot water bottle and other high-power electrical appliances (such as a hair dryer a hand warmer and a rice cooker) are used in a similar manner.1. Insert the input power cord of the electronic regulator into the dormitory socket or the plug and adjust the socket knob counterclockwise to point to the 0 position;2. Turn on the switch button of the hot water bottle (the high-power electric appliance without the button does not need to open the sw
