For a portable power source for your speedlights, use the Turbo 3 Rechargeable Battery (US / Canada / Japan Plug) from Quantum Instruments. This battery works with most shoe-mount and handle-mount flashes, including 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 speedlights and 750 flashes for handle-mount units.
The product offers two outlets so you can simultaneously power a digital camera and a flash, or two flashes. Cables are secured to the battery via 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 and sold separately.
The Turbo 3 is equipped with four LED status indicators for checking how much power you have left. Recycling times vary from 1 to 1.9 seconds, and it takes about three hours to fully charge the unit with the included battery charger. The product weighs only 2 lb and can be carried around easily with the included belt clip.
