Re: Pi5 12v supply
开云体育Sorry I just noticed the 2.5mm jack (can also use USB-C) looks like it can take up to 16vdc. Now that solves your problem and offers a fail safe too!!De Spence M0STO Sent while portable! please excuse typos. On 28 Jan 2024, at 04:11, Spence M0STO via groups.io <unavailable.equal@...> wrote:

These UPS hats just require a decent 5v 5amp supply to maintain a floating charge and a cheap 12v buck converter could easily take 12v and convert that to a 2.5mm DC jack and also provides additional USB Sockets for extra device power.
Typically you can stack up to 20 x 18650 in 4 extra battery hats, however, it will take days if not a week to charge that many cells in parallel.
I also own a few Nvidia Jetson Nanos too and they all have 12 x 18650 as the serve as light weight 24/7 online servers that are virtually crash proof.

?Gotta say, this thread has been entertaining. From what I can tell, the RPi5 wants USB-C PD power. The "Official RPi5 Power Supply" provides PD (27W), but is a wall-wart only. The OP I believe wanted something to run from 12V. So...
This takes 9-24VDC in and gives USB-A and USB-C/PD outputs. It is hardwired in to whatever power source you have.

This is a cigarette lighter/power point plug in that gives basically the same thing, a USB-A(QC 3.0) and a USB-C(PD) outputs.

I believe either one of these should power your RPi5. Personally, I think I would go with the CoolGear item as it supports a higher output (75W combined) than the Bangfun (20W) device.
