An almost ran
There was one other splitter that I really wanted to test, and had high hopes for, which is the Waveshare POE-SPLITTER-TYPE-C. Someone in an earlier thread had commented that they were successfully using one.
By the time I really got rolling on this, they had begun disappearing from Amazon. I was kind of stuck on the thing, so I found the original manufacturer and was about to order some shipped over. Just before completing the purchase, I noticed that there was a slight change in the specs from the units listed on Amazon.
One of the things that had liked about the Waveshare was that they advertised it as having a full SMPS, and that it used the SiLabs SI3404 switching power regulator. I like stuff I can find/read specs on, and they made a big deal about using this chip. Courtesy of the Wayback Machine, here is how they used to show the unit:
What I noticed on the manufacture's site is that they had quietly changed the chip. The newer units use a different chip, the Silan SD4950. Waveshare still advertises it as having a fully isolated SMPS, but they don't tout the chip, and Silan offers scant detail on the chip (at least in english). I contacted Waveshare to ask if they still had any inventory of the older units, they indicated that the supply had been exhausted.
I also tried several resellers to see if I could find some of the original units still in the pipeline, but did not find any that could be confirmed. The closest I got was placing an order with a seller on eBay who had initially confirmed his inventory was the original version. The order cancelled several hours later after the guy went to the warehouse with a screwdriver and magnifying glass and opened one up to double check. I really appreciate that guy. 
Anyway, I've given up on the idea of testing this unit.
