Update on my project. I have tried both of the following buck converters with good results. I¡¯m only running a fan, USB-Serial, and a soundcard so I¡¯m not loading it much.

The DROC meter should not be believed but its not far off. Both have operated on my bench from the same DC supply that is running my IC-7300 and I haven't noticed any noise.

I have also used them on a Pi 3 and the most significant factor is getting away from off-the-shelf micro USB cords and using cords intended for power.

?

So far no low voltage warnings on the Pi 3.

I have also added a Pi Power from Sunfounder and it seems to be working well. It has some suggested safe shutdown software so I am going to add that to the Pi.

?

Thanks for the suggestions.

Yep, unfortunately, but the cable does use 17awg wires for power, so it definitely can handle the current.

I'll let someone else decipher that page but my take on it is that it is 3A (15 watts) unless it able to?negotiate to get higher power.

So it would seem it would be better to use one of the PD ports and get?3A (15 watts)?versus the QC port and only get 10 watts.

Please correct me if I'm wrong.

Any USB-C standard power outlet will have the standard 5V, 9V, and 12V pins, you just need one rated at 28W or higher. Your 30W unit will work fine.?

The socket I put in my LiFePo4 box is this one from Amazon ($20.99):

There was a message a couple of months ago when someone was looking for the code and manuals. Someone may have picked up the hosting, but I don¡¯t think so. I will have to search my archives for the note. It came out on the PiGate list I think??

?FWIW, I ran my Pi5 yesterday for about 4 hours using the power socket I discussed.

My 24 AH LiFePo4 battery went from 91% to 89% charge. (Not hugely scientific, but suffice to say the Pi 5 didn¡¯t suck down a lot of power.)

Not a single warning message from the Pi about low voltage, etc.

IMHO, my Pi5 is going to be a great addition to my portable kit. I¡¯m still looking for an acceptable smallish monitor for it, but I assume that¡¯s the easy part. I expect this setup will draw a fraction of the power I used to use with my Macbook Pro 15¡± (2018, a real power pig). I have a 3D printed case that fits the Pimoroni NVMe base on its way, so that¡¯ll enable me to put the 5 into a nice protective case and tuck it into the big case where I stow my portable rig (Icom IC-7200).

Anyway, it¡¯s nice to have options. The thought of using an AC inverter with my portable rig so I could use the official power supply was crazy. (DC to AC and back again is stupid.)

I¡¯ll test this same setup with an external USB 3 SSD as well, and I¡¯ll report back here.

Cheers,

Ken van Wyk
