We use NetAlly LinkRunners here, the G2 most recently.

The G2 will load test up to 90W, the older AT2000 will do 30W. A nice bonus on
the G2 is the PoE power will charge the device. The copper TDR test, tone
generation, connectivity tests, and
For a quick check I use the Fluke Networks LinkSprinter 200 Ethernet Network
Tester, (Not what you originally asked, but I like to hear myself talk)
I installed wireless here in the 90’s and it has only metastasized everywhere
since. (I keep a 10 meg ½ duplex behind my desk to scare the newbies)
I don't know about other brands, but if you have Cisco Catalyst switches, many
have a built in TDR that can help with determining if you have a cable/distance
issue. In a building we completed a couple of years ago I found some of the AP
runs exceeded 100m (conduit plan not followed), which
I wouldn't suggest hacking together anything to test PoE. It's way more
complicated than it seems like it would be. If your test device said that a
link failed would you really know if it was an issue with PoE/Cabling or
your device?

Hey JJ,
Good to hear from you, thanks for the reply. It looks like (from the
description) the LinkRunner G2 and above will do the actual PoE load test I'm
looking for (not just repeating what LLDP/CDP is saying the capabilities are).
The LinkRunner 10G also appears to test the NBASE-T / 802.3bz
