Questions about vivitek Qumi Q8 black

According to the manual page 20: https://www.vivitek.de/Files/UserManual/Qumi%20Q8%20UM_10132016_German.pdf The unit has a repeat mode. Accordingly, at least playback should work. Unfortunately, there is no mention of automatic playback. I don't think it will work.

Probably not, video compatibility is stated as 480i, 480p, 720p, 1080i, 1080p in the manual and a video transcoder is not mentioned anywhere. If, contrary to expectations, it does work, the picture is probably not smooth enough, so I would consider a 4K player from the outset, such as Chromecast Ultra or Amazon Fire Stick or a NAS with a transcoder, etc.

no it does not have a 12Volt connection... so nothing with camper :-)

Hello, the simple answer: Yes, of course, with an adapter on the iPhone/iPad to HDMI. The more complicated answer: It depends on the app of the iPhone/iPad whether the function via "cable" is fully supported. Most streaming apps support this, but Apple itself does not allow the playback of purchased/rented videos (via Apple app) via a projector for legal reasons, for example. So brief summary: Zattoo, Netflix, VLC etc. = no problem.

Yes, it has. Supported formats AVI, divx, MKV, TS, DAT, VOB, MPG, MPEG, MOV, MP4, WMV.

It literally says so in the product title, directly below it and in the specifications...

No the qumi q8 does not have an integrated battery.
