A hair curling iron that forms spiral curls having an integral vacuum system and an internal heating tube is designed to eliminate the need for manual rotation of the entire curling iron when forming spiral hair curls. The curling iron provides a slot into which the hair is pulled by an integral vacuum fan mounted within the handle and controlled by an on/off pushbutton. When activated, the vacuum fan pulls the hair into the curling iron and around an interior heating tube. After several seconds, the pushbutton is released and a spiral curl is pulled out of the curling iron. A separate illuminating switch provides control of the heating portion of the curling iron. The danger of accidental burns is greatly reduced due to the interior location of the hot surfaces.

A battery self heating system for batteries that experience battery impedance or internal battery resistance when temperature drops. The system comprises an energy storage element applied to the battery terminals to draw energy from the battery. The energy is stored in a magnetic or capacitive storage device.
