The charging cable is supplied with the 87W MacBook Pro. The 87W (86.86W) is achieved with 20.2V x 4.3A. Of course, a safety factor is included here, but I would not exceed this number of amps by much. More amps could result in a hot situation ;)
Not this USB-C charging cable. I can't even run my DELL screen on my MacBook Pro with it. Just tried it... but the 80cm Thunderbolt 3 cable from Apple supports USB 3.1 and transfer rates up to 40GBit/sec. and works great on hubs and monitors, I connected mine to it:
Apple Thunderbolt 3 (0.80 m)
Hello,
This is a usb-c to usb-c cable. It only charges an iPad. Unfortunately it does not allow you to exchange files. You have to buy a new cable, the 0.8 m Thunderbolt 3 (USB-C) cable CHF 45.00 or Thunderbolt 4 Pro cable (1.8 m) CHF 139.00.
For my use this cable is unfortunately not very useful. I had to switch to the 0.8 m cable from Apple at chf 45.00.
So too expensive for the service provided...
Even if you have USB-C ports... it's useless... you can't connect an external SSD... Apple sometimes offers amazing things.
