Breaking the things down - we have
1. A USB module on one end of the cable - takes 24V in, lots of different styles / types available on Amazon / Ebay / Ali Baba, etc... Only challenge is finding one that is happy w/ 24V power, many are only designed to deal w/ 12V.... The connectors on the module are a function of the module, not anything that powers it.
2. A bracket for mounting - again lots of choices - many modules will come w/ brackets, especially those intended for motorcycles, boats, etc.
3. An XLR or R-Net plug - they are both doing the SAME thing, namely connecting to the chair's 24V battery system, just at different places...
4. An extremely high price for putting them all together.... (Though probably less than what a chair maker would charge for the something less capable....)
I don't know the exact pinout of an R-net plug, or where one could get just the plug, (I haven't looked) but the module is just connecting to the two wires in the R-net cable that power everything else in an R-net system other than the main power module... One could just as easily put a couple of terminals on the ends of the power lead (hopefully w/ a fuse) and connect directly to the batteries or anywhere else that's convenient....
The only part that is really critical is getting a USB module with the functions you want, the rest is just basic wiring... I haven't shopped for a module recently but I'd be surprised if cost for a relatively fancy one was more than about USD $10
