What is the maximum power draw of the DEWALT DCB104 multiport charger?

The DCB104 is a 4 port simultaneous fast charger for DEWALT 12V MAX, 20V MAX, and FLEXVOLT batteries. The maximum power draw is indicated on the bottom housing of the DCB104: 120VAC @ 10A = 1200 Watts. Actual power draw would approach this if four FLEXVOLT batteries were being simultaneously charged. The approximate peak power draw when charging 4 x DCB206 should be about 800 Watts.
