@ipg There actually is something that looks kind of like this that’s a standard(ish) for use in Point of Sale systems called “PoweredUSB”!

@xanarin @ipg Dell also used a similar thing once for their laptop DVD drives (apologies for the crap quality)

It can be possible to make an adapter that converts the funky connector into USB-C PD 3.1

Haha that would be awesome! It’s a perfect hacker project: it’s technically interesting and challenging while being completely useless 😂

That looks horrific. USB-C does 100W anyway. I would have chosen an internal battery that constantly trickle charges to make up the difference, or a separate power supply, anything, literally anything, than a custom USB standard.

@rastilin @xanarin @ipg USB-C has been around for what – 6 years? These Point of Sale connectors have been around for around 20 years.

@rastilin @xanarin @ipg Before you knock PoweredUSB too much, remember that back around 99-00 when POS systems starting using it, the primary USB spec couldn’t do more than 5V at 0.5A and USB-C was was over 15 years away.

These power devices that early USB just wasn’t even interested in dealing with.

And even the 1.0 versions of the USB-PD specs at 20V 5A is less than the the 24V 6A PoweredUSB ports available 20 years ago. (Although most were 12V 1.5A plugs in my experience, I worked on POS software for a few years so had tons of test hardware). It’s really only been about 5-10 years since the main USB specification caught up with USB-PD 2.0. And for a lot of those years, implementations of USB-PD were really spotty and unreliable so the hardware manufacturers didn’t have any motivation to move.

Plus… PoweredUSB also had the advantage of easily telling which way to plug it in, unlike a standard USB-A plug. For the late-90’s, it was actually pretty nice.
