When you are shooting a big assignment, traveling in remote locations, your camera or flash batteries are drained and your are without access to electricity, then the ideal solution is the Turbo 3 Rechargeable Battery from Quantum Instruments. This is a high voltage battery that works with most shoe- and handle-mount professional quality flash units and all Quantum Qflash, T-series and Trio/Pilot portable flashes. The Turbo 3 has the capacity to provide 1050 full-power flashes for shoe-mount and 750 flashes for handle-mount flash units.
The Turbo 3 has two outlets so you can simultaneously power a digital camera and a flash or two flashes. Cables are secured to the battery with locking sockets so you don't have to worry about a cable falling out while you are in the middle of shooting. Compatible cables for Nikon, Canon and Qflash Trio are available (sold separately).
This NiMH battery is equipped with four "fuel gauge" LED status indicators which keep you aware of how much power you have left. Recycling times average one second and it takes about three hours to fully charge the unit with the included standard battery charger.
Turbo 3 is Quantum's highest-capacity battery. It weighs only 32 oz (900 g) and can be carried around easily with the included belt clip.
