For power hungry digital cameras and flashes, Quantum stuffed twice the power into a smaller package. And, now you have two connections, for a camera and flash, two cameras, or two flashes! Photographers need reliable power now more than ever. Quantum Turbo 2x2 provides programmable low voltage for your digicam, and high voltage for your flash at the same time. Now your flash keeps up with your camera, and camera with flash. Be assured of reliability because Turbo 2x2 uses the latest Nickel Metal Hydride battery technology, visible "gas gauge", and Quantum's proprietary, built-in charging circuitry.
