Use the Turbo AC to power a small accent light, such as a Qflash with a snoot attachment, in place of a less versatile AC slave unit. Or use it to power a bounced fill "room" light positioned in the upper corner of a room, or a soft light with softbox or umbrella attached.
Just connect the Turbo AC to the camera using Quantum's XDC or YDC series cables and you're connected to a constant, reliable supply of voltage-regulated power. Turbo AC provides the same performance as the battery powered Turbo Compact - except Turbo AC is continuously powered anywhere in the world - from 100-240 VAC, 50/60 Hz. The only other thing you need is an AC outlet.
