Multiple PCs, or phones even. It’s very nice for using between my console, desktop, and Steam Deck.

Basically the controller has 4 pairing slots it will remember. The original PS5 it connects to is remembered as slot #1, but you can manually change it by remapping it to a different slot.

The different slots are activated by holding the home/PS button and one of the 4 face buttons for a couple seconds, or hold it for about 5-ish seconds to enter pairing mode for that slot. Pressing the PS button alone like normal defaults to the last used slot.

The controller does need to be turned off before switching devices, which can be done just by holding the PS button for 5-ish seconds. But I can be playing a game on PC, get a message from a friend to hop on Nightreign on PS5, disconnect from my PC by holding the PS button for a few seconds, and then press PS+Triangle to turn on the PS5 using the same controller.

Way better than my previous setup, which was to have 1 dedicated PS5 controller and 1 dedicated PC controller, then bitch and moan if I ever had to unpair/repair the second controller on PC or try to find my USB cord to pair again with PS5.
