USB-C Extension Cable for Power Delivery

After seeing the impact a dual Xeon RX 580 GPU etc. Mac Pro 5,1 had on my electric bill, I’m spinning that beast up only when necessary! So I’ll be using the laptop slot I had built into my computer stand more and more. Which means having power cables draped everywhere from the grommet insert is less than ideal. So... 

• Anker MacBook Pro Charger, 100W USB C ($30 and comes with a 5' USB-C cable)
• Faracent USEC-2M 2 meter USB-C extension cable ($14 and purportedly transmits up to 5A, so, a full 100W)
  

The extension cable is necessary so I can have the wall wort plugged into the UPS on the floor and have an easily accessible USB-C female port I can plug a USB-C to USB-C cable, or for older and newer devices, a MagSafe cable, into, depending on what laptop is in the slot.

I currently have it hooked up to a MacBook Pro 14" M1 Pro via an Apple MagSafe 3 cable and can confirm it’s negotiated 19.5V and ~.25A (which is what it was drawing connected to a 67W charger USB-C to USB-C, no extension cable), so, yeah, it works. A simple setup but it’s just what I needed.
