The plethora of add-ons for the Pocket 3, makes it hard to decide which ones are best. I have seen many "charging dock" fittings - some better than others, and I think this one by K&F is a good one.

The base is metal, including the dog ears at the bottom, which are annoyingly attracted to reclining backinto the base - but a little effort and they extend to be connected to the curved "GoPro" type holder.

The base will permit you to charge the Pocket three, by connecting the cable to the type "C" fitting on the base. I wouldn't count on the base being stable enough to leave standing though, as its footprint is small and the camera is top heavy, but laying on its back, it works just fine.

The base only works when you remove the extension handle from the Pocket 3, and it also won't work with the battery handle, but it attaches aggressively to the bottom of the Pocket 3. I found that once I had the clamps inserted in the grooves in the base of the Pocket 3, and then used my thumb and forefinger to be certain the clamps were mounted fully, then the base was never going to just fall off.

K&F make fine products. This small base comes with a connecting arm for the dog ears on the bottom, and of course, it's plastic like all the other GoPro fittings, but it has a very nice curve on it that will permit you to carry the Pocket 3 on your chest and get nice footage.

It's a solid piece of gear from K&F, and I recommend it.
