[How to do instruction] The Wall-Wart thread

[the_bertrum]

I run my two Pi4 based systems with the "official RPi supply", but my Pi Zero is powered with an old charger from a circa 2016 Samsung phone. All provide sufficient power and with hindsight, I'd have not even bothered with the official supply for the Pi4 set-ups, I've plenty of old phone chargers around the place tat would have done. I don't use any USB powered peripherals though.

I've yet to hear a convincing argument for fancy linear power supplies and the like, so I've never tried any of those. Likewise, having never tried one, I can't say I wouldn't hear a difference either.
