testing USBC PD gear

[mr jones]

Hey all!

I really enjoyed finding out about which good USBC Power Deliver (PD) gear via Benson Leung's testing (see https://www.engadget.com/2016/02/03/benson-leung-chromebook-pixel-usb-type-c-test/).  However, this info is out of date as it was too laborious for him to test everything on an ongoing basis.  I had a bad part that I've since replaced, but I'm not entirely sure it's a good replacement.  

Does anyone have a way of testing USBC PD gear?  Specifically one of these and some USBC <-> USBC cables.  I'd love to know that I'm not going to fry my laptop or start a fire (or both ;).

Thanks!

Hey again!

Does the shop have any interest in purchasing one of these, "POWER-Z usb tester"? They're about $50-60:

https://www.ebay.com/p/Chargerlab-Power-z-USB-PD-Tester-Voltage-Current-Ripple-Dual-Type-c-Meter-Km001/21005785563

And seem pretty awesome:

Seems like it would be a part of the electronics area, so it is Krux's budget and decision.

So does it do anything other than measure current?

Krux,

Erm...no?  I mean, I don't know how it all works, but, "It supports USB PD 3.0 decoy and packet analysis,  multiple protocol detection, QC3.0/2.0, FCP, SCP, AFC, online synchronous test and off-line data recording, E-mark cable test, and Type-C resistance testing." according to their page. Sorry I didn't send that page with all the good details upfront.

Ok... well it looks cool. Not that I really have a use for it, but I could
see how it could be useful if you're debugging some USB power stuff.

Krux,

cools!  it doesn't look like actually buying one is that easy.  if the shop is interested, I'd be happy to figure how to procure one and then y'all can just reimburse me? what ever works. I'd also be happy to produce a basic "101 to usb power testing" based on my results.

cheers,

I think if you're willing to teach a class on USB Power testing, then that makes it an easy sell.  I'm on board.
