Personally I just use ESP32 (specifically Lolin D32) in an altoids-type box with a run-of-the-mill small USB power bank taped to the back. Usually with some level shifters and stuff to run the Blinkenlights (FastLED + ws2813).
If that's too ghetto for you, have a look at the M5Stack series. A main unit (ESP32, screen, speaker, TF card reader, in a case with some buttons) costs $35, and the battery module you can stack on is $10. There is even a keyboard and a gameboy-like attachment.
I like the look of the Precursor, but personally the FPGA is a bit off-putting, just because I've never gone down that road.
