After falling absolutely in love with it but realising i needed to keep it in a different room for abs i quickly decided i needed a raspberry pi running octopi with a webcam to keep an eye on it.
Raspberry pi 3 power supply 12v.
I ve tried a 5v 2 4a supply and a 5 25v 2 0a supply.
The recommended amount is between 700ma for a raspberry pi model a and up to 2 5a for a raspberry pi 3 model b see power supply requirements in the magpi issue 56 page 39.
The official mains power supply provides 2 5a at 5 1v.
Usage depends on what you re doing with the pi.
I recently got my first 3d printer a prusa i3 kit.
For low power projects you can reduce the amperage quite a bit before it affects performance or stability.
An individual gpio pin can only safely draw 16ma.
The raspberry pi boards typically draw much lower amounts between 200 and 500ma.

Get it as soon as thu oct 8.
Unfortunately the 12v multi supply i have has 3 cigar lighter type sockets and 4 usb sockets but the usb sockets are only 5v 2 1a.
For raspberry pi 4 we recommend our 3a usb c supply.

Powering a raspberry pi from a 12v power supply.
Miuzei raspberry pi 3 b case with fan cooling and 3 heat sinks 5v 2 5a power supply with on off switch cable for rpi 3 b 3b 2b 4 7 out of 5 stars 1 092 16 59 16.
The pi 3 has a recommended power supply of 5 1v at 2 5a which covers most situations.
The gpio pins can draw 50ma safely distributed across all the pins.
The pi returned under voltage errors for both and either would not fully boot or randomly rebooted.
For raspberry pi 0 3 we recommend our 2 5a micro usb supply.
Earlier models demanded a lower draw of 5v at 1a but in practice greater amperage is usually preferable.
