The Razer Kishi V2, the Backbone One, and Gamesir G8+.Lifewire / Rob LeFebvre
All three devices let you drop in a smartphone, either connected via USB-C or Bluetooth.
It’s a little less beefy than the former but more full-sized than the latter.
Unfortunately, there’s no little lip like on the other devices to keep the phone in.

Better yet, it can be used with your Nintendo Switch.
The Switch itself even fits inside the G8+ for an odd but strangely compelling way to Nintendo.
you could even connect via the USB-C controller to a PC, similar to the Kishi above.

Yes, it’s small, but that’s a feature, not a bug.
The Backbone One has been through various iterations, and the current USB-C version is the best.
It also enables game recording with unlimited cloud storage for all your gaming videos.

Not too shabby if that’s something you do on the regular.
Oh, and be sure to pick up a case.
It’s just lovely.
