How can I-Tech produce so much power with only a 20A plug?

The combination of Class-I technology and an innovative PFC power supply enables I-Tech to very efficiently draw power from the A/C mains and deliver it to the speakers. This high efficiency, coupled with a significant amount of energy storage, allows I-Tech to deliver high power much more effectively than conventional designs, and thus reduces the demands on the power cord.

For more information, read this short "Tech Made Simple" article.

Also, to see real current draw numbers for I-Tech, refer to the AC Power Draw and Thermal Dissipation sheets here
