My previous replies are outdated. Recently I found that the laptop supports 5V3A PD charging. I made the test using a 24VDC5525 to USB PD 100W converter. This device is step-down i.e only reduces voltage. So I used a bench power supply to input 7.5V, the only PD protocol below 9V is 5V3A. For some reason the USB meter won’t work as it’s internal resistance makes the current unstable and the converter emits high-pitched whine, but without it the laptop draws about 5V2.7A and the bench power supply outputs about 14.8W(the DC to PD converter has about 90% efficiency).

5VPD input w/o USB meter
The current increase from the input power is consistent with the charging power increase on btop
My finding is not very useful since most, if not all, PD chargers are at least 9V2A18W, I can’t find any 5V3A PD charger on the market, the 5V1A, 5V2A, 5V2.1A, 5V2.4A etc. they are all non-PD. The laptop only supports PD protocol, it won’t draw current from a non-PD charger even said charger current is higher than 3A.
EDIT: Didn’t work, when plugged into a real 5V3A socket (it’s possible to find one, this time is on a train), the laptop only pulled 2.7A for less a second before ignoring it(the charge light flickered once).

5V 3A USB-C PD chargers are common although they usually also support higher voltage profiles (so won’t be preferred by the framework laptops). Raspberry Pi LTD even has a USB-C PD charger that supports 5V 5A (with additional higher voltage profiles as well).
Sorry for the misunderstanding. I was trying to say that it’s hard to find a 5V3A ONLY power supply. Since most PD power supplies that capable of 5V3A also have higher power outputs, the laptop will request a higher power instead of 5V3A, making it difficult to tell whether the laptop supports 5V3A PD input
There are tons of 5V 3A only pd power supplies, just not ones that use digital pd negotiation as 5V 3A is the max you can do using resistor based pd negotiation.
Did anyone encounter that chargers stopped working after one of the recent firmware updates again?
I think that one of my 20W USB-C PD power bank + charger device used to properly charge the laptop. But now it stops after less than a second. It’s an Urban Vitamin Saratoga charger.
I might be mixing up things though as I rarely use that charger for my Framework laptop. So if none of you has encountered any regressions, I am inclined to believe you.
You talking about the new 3.06 bios and firmware update?
Yes, something very strange with chargers, I am seeing as well. I have only just updated and testing one of my power supplies so far. This is a 100W usbc dock that I have been using perfectly fine for months.
After the 3.06 update, I had to power-cycle the dock to get it to even connect, then it was charging my laptop fine. However, the laptop limits its self to a very low power mode, with cpu cores limited to about 544MHz causing terrible performance.
I am running
UEFI BIOS
Version: 03.09
Release Date: 04/22/2025
EC Firmware
Build version: azalea_v3.4.113385-ec:c25dec,os:7b88e1,cmsis:4aa3ff 2025-04-14 01:55:38 marigold1@ip-172-26-3-226
Current image: RO
PD Controllers
Right (01): 0.0.1C (MainFw)
Left (23): 0.0.1C (MainFw)
and cannot really pinpoint at which firmware release the issue appeared, unfortunately I use that specific powerbank for this specific laptop only a few times a year.
Could you maybe report this issue upstream on this repo so it is known from Framework officially and may receive a response there too
