Nikon AS-E900 External Multi-Flash Adapter (no bracket) for Nikon Coolpix 900, 990, 995 and 4500 Digital Cameras

I was hoping at least one of the 3 extension ports would be a standard flash single pin extension. But no, they are all the Nikon 3 pin connector so all u can connect is another Nikon device with the 3 pins. The shoe is standard.
