After setting up my FW12, I measured the charging speed of every USB-C charger I could get my hands on.
Here’s the compiled data: Framework 12 USB-C Charging data - Google Sheets
The spreadsheet also contains a link to a Drive folder with pictures of all chargers.
Now I need your help!
If you own a USB Power Meter and a Type-C charger that’s not yet on the list (wall wart or power bank), please post pictures of the charging speed and the output specs printed on the charger (like you see in the linked Drive folder).
If you have any notes, please include those as well.
I’ll update the spreadsheet with any data posted here, plus everything I gather myself.
Important:
-for consistency, FW12 needs to be turned on and idling
-FW12 needs to be at a low state of charge (about 10-30%), otherwise it may restrict charging power
-USB Power Meter needs to support all relevant protocols (PD, PPS etc), lest it becomes the bottleneck
-USB cable needs an E-marker chip with high voltage and current, lest it becomes the bottleneck
For reference, the cable I used is a black braided 1m long Nimaso USB 3.2 Gen2.
The E-marker reads 50V 5A and I measured 63mΩ resistance on GND and 86mΩ VBUS.
