Wall outlets in North America put out 120 volts, not watts. Watts is the power used by the device plugged into the wall, volts is the electrical potential in the circuit (think water pressure as an analogy). A light bulb consumes 60W. You could power 333 light bulbs with 20kW. An AC unit consumes around 1kW. You could power 20 AC units with 20kW.
