Nikon External Battery Pack

I have the Nikon SB-800 on camera flash, and I have had issues with the recharge time. I was shooting a graduation and unfortunately it wasn't recycling quickly enough. I purchased the Nikon SD-8A external battery pack, and I have not had any problems with the flash recharging time. The following video demonstrates the external battery pack.


I would recommend this to all. I have been very pleased.
