Hello I already went through framework support for this and they were not able to give me any solution, but I figured I could write about it to see if anyone else has this issues. In my talk to support they said they are working on a firmware update to fix this so I hope it gets resolved. I have a Anker battery (this one) that I bought in anticipation for my Framework 16, however when I got it, it essentially refused to charge it at any reasonable speed. With the framework USB-C cable it would charge at 0.1w (reported by the battery) then spike to anywhere from 3-18w, when it would do so windows would detected it for short periods of time. [battery_behavior] When I tried to use the anker cable included with the battery it charged consistently but only at 20w. The battery is capable of 140 out, and it charges all other devices as expected. During my talks with support I also tested all the power capable ports with and without USB-C expansion cards and they all behaved the same.

I talked to support for about 2 weeks and they’ve just said that they are working on fixes with PD issues

I have sent an email to Anker Support (even if its probably useless) with the issues on charging the laptop and how other Anker products work as expected.

Some interesting behavior with the 737 and an Anker dock. I have an Anker docking station I plug my FW13 into for video, power, Ethernet, and other peripherals. This “one cable solution” dock charges my FW13 at about 60 to 70 watts through the main USB-C cable, it also charges other devices like headphones, game controllers, tablets, and pretty much anything else with a USB-C port throught that main USB-C cable… except for the Anker 737. With the Anker 737 it won’t accept a charge and will attempt to charge the docking station at 0.1 watts. Could it be possible that it’s more to do with the Anker 737 itself and not entirely the fault of the FW16? TL;DR Anker 737 won’t charge from an Anker docking station. Is the FW16 really the whole problem? Anker Dock Link

That makes this even more interesting, maybe it has trouble communicating with devices that can act as docks? It wouldn’t completely explain everything but that’s all I can come up with. What motherboard do you have?

I can confirm that my Anker Prime and Anker PowerCore Reserve both work on the Framework.

I don’t really see performance changes since the battery just doesn’t work correctly.

That is good, must be a seperate bug then. With the issue I was referring to, the cpu pins at .5Ghz, and you definitely notice the drop in performance. (happens across windows, ubuntu, fedora) I brought it up since the charger will also charger very slowly when this happens.

For whatever it’s worth, I’ve plugged my FW 16 into a solar panel outputting only 3-8W and the FW didn’t do anything strange.

Trickle mode worked for me. I was able to get the laptop to pull almost 90w from the anker 737 battery. If it matters, i’m also running the latest bios with a 60% charge limit since my laptop is more like a desktop right now.

Does the cpu by chance throttle to .5Ghz when charging with a pd charger over 100w?

I’ve detailed my issues with some related issues in this post.

Issue is still present with fully upto date BIOS and fedora 40.
