Recently B&H added a Hensel Porty head adapter which allows you to use a Profoto flash AC pack heads on Porty battery powered packs.

There isn't a photo of it on their site, and it doesn't say whether it accepts the Profoto Pro heads or the D4 heads. Anyone know?

Man, this would be outstanding if I could just get the Porty 1200L and use all my Profoto stuff with it.
