From Amazon:

　　The Turbo Compact ( also known as the Turbo C) can power your digital camera and flash together! The proper voltage for different cameras is automatically adjusted by the battery. Powering a different camera or flash only requires the changing of a cable. Charges in 1.5 hours and weighs only 16 oz. With a shoe-mount flash, this battery features a 1.4 sec. flash recycling time, 400 exposures with full-power flash and 250 to 350 exposures while powering both the flash and the camera. A self-contained thread screws into the socket on the bottom of your camera and the Turbo Compact accepts tripod threads for mounting.

　　I bought this when I was doing a lot of event photography. Selling because I'm not doing so much of that any more. The body and electronics are in in excellent+ condition, both cosmetically and functionally. However, THE BATTERIES ARE ALMOST DEAD! The still have enough life to prove the item works, but they have to be replaced. I just called Quantum in Chicago, and their price for doing this is $140. So, when you get it back it will be like a brand-new unit, fully checked out and with new cells. That's why I am asking $40; for a total of $180, you get a brand new, factory warrentied unit.

　　I also have a Nikon FLASH (not camaera) cable. I am asking $20. Of course, you can get any type of cable you need to make this batter work sith any camer and/or flash that has a high-voltage/external power input.
