Pretty much, they magnet together though so you can split them apart and use them as normal with other devices.

The latest USB power delivery standard allows for new voltages of 28, 36, and 48 volts at up to 240 watts at 48V. My current Dell workstation laptop uses two 20V USB C connectors to achieve similar.

It works pretty well for me, but I use Firefox nightly.
