Pixelbook won't charge from 2.4A power bank |
||||||||||||||||||||||||
Issue descriptionFiling this bug to avoid polluting issue 876969. I'm using a Pixebook with firmware 9584.160.0. When below 100% battery, I hook it up to my Anker 20AH power bank using a USB A-to-C cable from the recommended list. The bank supplies 2.4 A per port. Initially, I get the warning notification that I'm hooked up to a low-power charger. That'd be fine with me - sitting in a cafe somewhere, I'd be happy to just slow the discharge rate. The charging indicator icon appears, but a minute or two later, it disappears. Similarly, in the shell, the battery_firmware info AC_PRESENT flag is there temporarily, then disappears. Doing some reading, I found that this *might* be because the bank doesn't support a new Power Delivery standard. But I'm still puzzled at why the Pixelbook isn't able to make some use of this bank (an AK-A1271011).

Flagging for triage (I probably shouldn't have unfairly bypassed the proper channel).

Please file a feedback report and include the listnr link so we can look at the log. It's somewhat unlikely that someone at Google will just happen to have this charger lying around. Even I don't have this particular charger.

Feedback was originally filed referencing this bug, but I didn't know about listnr/ at that point. Cool. Here we go: https://listnr.corp.google.com/product/208/report/85713450506

From related issue 876969: "With the firmware in the beta channel (Google_Eve.9584.174.0), low-power charging works without problem." I'll retest this when that firmware hits my device.

This is fixed with Google_Eve.9584.174.0. I jumped on Beta, plugged the Pixelbook into the powerbank, and was able to sustain a low-power charge rate from 80% up to 100% battery. Yay! |
