Charging quirkUses a simple 5V charging circuit with no USB-PD negotiation, so many USB-C PD/GaN chargers and E-marked C-to-C cables charge it slowly, only when powered off, or not at all. Use a basic 5V USB-A charger with a USB-A-to-C cable.Why this happens & how to fix it →How far can it go?
Runs everything up to PlayStation 1 at full speed, and pushes as far as PSP with some compromises.
