1. A power strip device for delivering power to a master load product and multiple slave load products, said power strip device comprising:
- a power plug coupled to a utility power source to receive power from said utility power source;
a master power outlet for delivering power to said master load product;
multiple slave power outlets for delivering power to said multiple slave load products, wherein said slave load products are peripheral devices of said master load product; and
a control circuit electrically connected to said master power outlet and said multiple master power outlets for controlling ON/OFF states of said master load product and said multiple slave load products, said control circuit including an inductor, a reed switch and a switching circuit, wherein an induction current flowing through said inductor is greater than a threshold value when said master load product is booted, such that said reed switch is switched to an ON state to close said switching circuit and enable said multiple slave load products connected to said multiple slave power outlets, and said induction current flowing through said inductor is less than said threshold value when said master load product is powered off, such that said reed switch is switched to an OFF state to open said switching circuit and disenable said multiple slave load products connected to said multiple slave power outlets.
