What's a Tronix Speedfire? It's an A/C power supply for your Canon Speedlite or Nikon Speedlight.
Simply plug one end of the Tronix Speedfire's cable into an A/C wall socket, the other to your Canon or Nikon flash, and voilà! You can kiss replacing those "AA" batteries, over and over, goodbye! And get this: The Tronix Speedfire recycles your flash in less than a second! I'm a big fan of faster recycle times.
The Tronix SpeedFire provides power to the flash only. Your flash's other functions, such as the LCD display, exposure processing, and other controls, are still powered by the internal "AA" batteries housed in the flash unit. But those functions don't drain much power. It's the flash itself that depletes your batteries and the Tronix Speedfire replaces the need for batteries for that power-depleting function.
You might wonder about overheating with the fast recycle time which enables you to shoot repetetive flashes in a short period of time. That's always a problem with small flashes regardless of what's powering them. Innovatronix recommends a cool-down period after firing 40 continuous, full-power flashes to avoid any damage. That's great advice regardless of what's powering your flash devices.
So check it out! The Tronix Speedfire from the good folks at Innovatronix. They also sell them as kits, with a sotbox and adaptor for your flash. If your a Facebook person, like I am, check out the new Tronix Speedfire Facebook Page and click "Like."
