"Magic Mouse and Keyboard: I recently purchased second hand Apple Peripherals for my M1 Mac mini that work perfectly however the battery is running low, I tried to plug them in to a USB type C plug and it wouldn't go in, Does anybody know what port they use to charge?"

Which Adapter:
If they run off of a battery, it will eventually die out. Once the battery dies out, it is time to resin tall the battery. When you say "second-hand", do you mean that they are not of Apple brand? If so, contact the manufacturer. If they are Apple, however, then see if this adapter works: USB-C to USB Adapter - Apple Support
