Lumedyne Flash Accelerator Can The Lumedyne “X” is able to double (or more) the flashes per charge of the flash’s internal AA’s while also cutting the recycle time of all settings about in half. The Lumedyne model number that fits the Canon™ style flashes is the VXCA. All chargers and charge cables are included. No additional cables, brackets or adapters are needed.
Once you connect the “X” to your flash, then turn it On, the flash simply recycles much faster than with the AA’s alone. The flash will perform all of its normal functions the same as before. The “X” Flash Recycle Accelerator will help with the recycling after every flash. When you are finished, just turn it Off and unplug it from your flash. Recharge it later from your home or vehicle.
The Canon™ style flashes have a high voltage connector on the side of the flash. It is covered with a rubber cover that can be pulled open and folded out of the way. The Canon™ brand flashes that have a similar high voltage connection include the 430EZ, MR14-EX, MT24-EX, 480G, 540EZ, 550EX, 580EX, 580EX-II, and the new 600EX-RT.
