More About Double Male Adapters

A pipe/hose fitting adapter is used to connect straight pipe or hose sections, to adapt to different sizes or shapes, and for other purposes. 

Pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe & hose fittings. It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow items with different threads to be connected together. They are used to fit straight / tapered end hose or pipes. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam. 

A coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be joined, welded (steel), brazed or soldered (copper, brass etc.) together.

Alternatively if a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female.

If the two ends of a coupling are different (e.g. one NST/NH threaded and one NPT threaded), then it is usually referred to as an adapter.

Fairly effective.
While I didn't bother reading instructions, it functioned as I intuitively thought with some slight troubleshooting. For example, using the correct USB-C for power or data. Connections to support an external monitor needs power toggling occasionally. Patience paid off. Expected a subpar Chinese knock-off (with questionable safety standards). But works very well, but can get warm.

Lots of great uses for this.
This hub is essential for a Quest or other virtual reality headset if you want to stream HDMI video to it. It allows you to hook up the HDMI source AND a power supply to feed to the headset to prevent the battery from running down.

Defective device
This device is very low quality, worked just once for few minutes with my macbook pro with my teleprompter and that's about it. I couldn't use it anymore. Defective device. trying to get a replacement.
