The standard Apple charger for my MacBook Pro charges it at 87W. It was particularly difficult to find USB-C Ethernet adapters that also allowed pass-through and listed their pass-through performance specifications. This was one of them, explicitly listed as 87 watts. Unfortunately, it runs with 81 watts (screenshot attached). It's a small difference, but I still think it's wrong. If I'm wrong correct me and I'll revise my review and rating. UPDATE: After upgrading my system to macOS Big Sur, the device stopped working. After a lot of research I was able to get it working by 1) removing the "USB 10/100/1000 LAN" device from the network settings using the minus key and confirming that I don't want the device to show up after a reboot. ; 2) Shutting down the computer and resetting the SMC on my MacBook (press and hold Option + Ctrl + Shift + Power button for 7 seconds); 3) turn on the computer; 4) add the device manually through the network settings, button "+", "USB 10/100/1000 LAN"; 5) After adding, go to "Advanced" and "Renew DHCP Lease"; 6) Disconnect and reconnect. ^ This was the ONLY way to get both POWER and ETHERNET back. Hope this helps some people.
