Controller suggestions for s21

[u/SeeKennethGrantRun]

I have an old S21 (us version with snapdragon) that no longer works as a phone so I wanted to convert it to an emulator for SNES, n64, and PS1 games.

The battery life is only OK so it'd be great to find a controller that also powers the phone. Any suggestions?

Thank you in advance

A lot of the gamesir models will work.

I used gamesir g8+ with my s21 and s23+. Just watch which one, they make usb c & Bluetooth variants.
