I was gonna mention something like a USB Type-C cable, but that's not really electricians' territory, is it?
USB-C is kinda sorta hermaphroditic.
When USB-C-compliant devices are connected, they have to negotiate which side is upstream and which is downstream. So yes, they're hermaphroditic, just like snails.
In contrast, the non-compliant USB A-to-A cable that Ugreen uses with its own devices is closer to hyenas. If you know, you know... and don't you wish you didn't.
My mpcie to pcie x4 adaptor uses an A-to-A cable, also says on the board to not plug in USB devices. :D
that "kinda sorta" is doing a lot of work there.
Here's a handy reference: everything downstream of a plug socket is electronics, everything upstream of a plug socket is electrical.
Sincerely, an electronics engineer that works in the electrical field.
USB-C is specifically designed so it can swap between different modes safely by way of devices being able to communicate what they need from a plug via dedicated pins in the socket. So yeah, you can have USB-C male/male cables and it's going to be safe as long as you use it with compatible devices.
Pfisterer HV terminations are male to male. They also have big butt plugs for when they're not in use. Kinky Germans.
