Thank you for the testing demo, I recently ordered the Drok USB Load as well as a RuiDeng UM25C USB Tester, should be here in a day or two. I'll also try my RockSeed RS310Pro as power source to try to duplicate your test here.
BTW, that sure is a nice Flir Thermal Camera that you are using (I can't quite make out the model # in your video), not in my current budget (No pun intended), but a thermal camera may make it onto my wish list in the not too distant future. They are spot-on for spotting PCB problems, as well as other equipment.

Thanks for the kind comments. The FLIR camera was a splurge but sure has been handy. It is a FLIR model TG165.

Thanks for the model # @@DanPattenAudioG33k 👍

A great application for these variable loads is to accurately gauge battery strength. Even dead batteries after all have voltage. You could use anything even a bread board with a varistor you don't need to spend $50 USD for this gadget. But it's cool to observe these necessary experiments to understand fundamentals to electronics. Watch an electrical engineer send 8 hours to troubleshoot a variable speed motor drive. It's easy to become bogged down in theory then call a trainned electrican and the electrican will have the item repaired with no schmatic and only a VOM. Very interesting and for the intended scope, and small dimensions very effiecient device.

Is the setting only in terms of current, or can you set a fixed power, say, 5W which would make it automatically pull slightly over an amp to compensate if the input dropped a bit below 5V?

[@DanPattenAudioG33k]

You can set the load in Amps or Power. However, my unit does not work as a constant power load. As in you example, the unit will not dynamically adjust the load with a varying voltage to maintain the set power. That would be a nice feature.

@@DanPattenAudioG33k Yes that's exactly what I was curious about, I appreciate the answer! The constant power feature would be cool, but hey, for $15 I guess you can't expect too much. Still seems like an overall useful device, I just ordered one to play around with.

[@DanPattenAudioG33k]

Agree :)

@@DanPattenAudioG33k Amazon got it to me overnight and I love it! Goes especially great with something like the FNIRSI FNB58 inline to trigger different voltages via PD / QC.
