No, the SP Power Pack is a high voltage device driven by a 12 volt lead
acid Panasonic style camcorder battery. It connects directly to the
T32's external input connector. The output is 305 volts DC at 500ma.
It's a near clone of a Quantum Turbo Battery and uses Quantum's own
cables to connect to various flash units.
I have cables for the T32, Canon 540EZ, Sunpak 422 and Sunpak 522. I
haven't injured a flash with it yet. But I am careful not to fire too
fast without letting the flash cool.
