I was charging a new to me 2017 FXS recently and when I unplugged the 110V cable, I noticed it was quite warm.
Yup, same here, when charging with 120 and OEM cable. Before switching to 240V I switched to 14 AWG, which kept the cable cold but plug warm.
If you can charge at 240 VAC, it will greatly reduce the current in that cable and then perhaps even that cable will be okay at 240 VAc. A lot less heat at higher voltages on Zeros because the OBC will lower the current draw by half to get the same wattage.

Ayup... that's the better way to go!
I do have access in my garage to a J1772 charger for my Chevy Bolt. So I guess I could order the J1772 adapter and charge at 240 volts.
However, for just $10 I could order a computer cable off eBay or elsewhere, that is 14 awg compared to the OEM cable that is 16 awg. I think I will try that first since it is a much cheaper route.
For sure, go AWG 14 . No need for AWG 12 imho but the AWG 16 provided is just not good enough for the Amps needed.
If you have 240 in the garage, then you should use it.
I have two solutions for mine
A) I installed a NEMA 6/20 outlet, and put a 6/20 plug (actually the ( - - ) low amp variety on a 14 AWG cable.
B) I fabricated my own J1722 adapter. There are several topics on this in this forum. Search and you shall find!
My solution was an 1772 Female I ordered which I attached to a section of aluminum pipe I happened to have which i could slip snuggly into the empty frame tube in the rear fork. At the back end i just attached a short charging cable to plug into the existing input when used.
See pics.
Good luck!
