Yes, the gimbal should be compatible with both GoPro Hero 4 cameras.

These Gimbals are compatible with the GoPro Hero 5 Black: https://www.digitec.ch/de/s1/producttype/actionkamera-zubehoer-2142?pdo=1769-12885:200788|951-9365:309405&tagIds=520

Hello - I can't imagine that... at least because the batteries are in the handle and therefore the power supply would be missing. Unless I misunderstood the question, sorry.

I don't think so, because the USB port for connecting is tailored exactly to the dimensions of the Hero 4.

This stabilisator works only with those models : Hero 3, Hero 3+, hero 4 Silver, Hero 4 Black

there are two times two batteries plus a charger in the scope of delivery

There is... Man see picture no. 5

No.. Not even with Gopro 5. Only GoPro 3/4 because of a MiniUSB adapter.

Hello Cris Gass, I have purchased exactly this part - but the USB stick does not work on my MAC (?) I have to find out how to install the new FirmWare 28.01.2016. Probably I have to try it via my laptop (WIN), maybe I'm lucky and my laptop recognises the USB stick. would contact me again. mfg Ernst Baur
