Accsoon SeeMo 4K Wireless Video Monitor for iPhone & iPad - HDMI to iOS Video Capture Adapter | 4K Surveillance Converter | Turn Smartphone into Camera Monitor (Black) - Perfect for Live Streaming, Film Making & Video Production

A pet peeve of mine is when a device is not operational out of the box... in this case, the battery and HDMI cable. It's been a week since device arrived it still sits in the box. Because stand alone batteries cannot be shipped to Hawaii, I have to go to the single camera store on island and have them special order a battery -4 weeks, at least. I hope this works as waiting for a battery means I'll be beyond the Amazon return window if this doesn't perform. I see mixed reviews, especially about true 4K support and oddly not 60fps support. Another weirdness is that the SD Card Reader only reads? So cannot record to it? Third issue I'm having is no way to ask ACCSOON if the Powercage II pro will fit my 13-inch iPadPro... it only talks about the old 12.9 iPadPro. I think I wasted $179 and should have looked for a USB-C option rather than this HDMI option.
