500 Watts is the maximum capacity of this transformer including the power surge
It converts 110/120 volt USA power to 100 volt Japan power AND 100 volt to 110/120 volts (means it will convert the American power to Japanese power and also convert Japanese power to American)

Remember to leave at least a 100% margin for power surges/spike when buying a transformer. For power tools, laser printers and heating appliances like Rice cookers, coffee makers, toasters, halogen or fluorescent bulbs you must leave a power spike margin of 4 times.
