We are super excited for this light! Finally, you have the power of a TTL flash with the versatility of a self-contained battery. NO POWER CORDS!!! A fully charged battery gets you approximately 220 full power pops. At about ten times more powerful than a hotshoe flash, that's a ton of juice! You must separately rent the Profoto Air Remote TTL-C for Canon or Profoto Air Remote TTL-N for Nikon in order to take advantage of any TTL functions. Our units come with a Profoto Fast Charger which charges the battery in about half the time as the normally included charger.
