I would like to have an XQD Dongle made that will have a XQD standard plug that converts to a double XQD connector. I wish to plug the cable into a camera with a single XQD port and write to two XQD cards at the same time. I don't want a simple dual wired connector, I can do that myself. I want a connector that is remotely powered by something other than the camera. The poer source could be small battery or usb. It can't rely on the XQD port for power because it may damage camera. I'm trying to make a mirror for backup.
