Oh that is good to know! I measured 20V/3,?A on my barrel jack adaptor, now wondering if it can actually do 5A as advertised. Is there a way to query the cable

Oh that is good to know! I measured 20V/3,?A on my barrel jack adaptor, now wondering if it can actually do 5A as advertised. Is there a way to query the cable for what it will actually report as supported voltages / current?
- baybal2 6y agoEasiest way is to get a PD tester. The hard way: page 363 https://usb.org/sites/default/files/USB%20Type-C%20Spec%20R2.0%20-%20August%202019.pdf https://usb.org/sites/default/files/USB%20Type-C%20Spec%20R2...
- MrBuddyCasino 6y agoDid some more research. I don't have a linux system with usb-c rn, but one can maybe query the emarker VDO in sysfs: https://people.kernel.org/bleung/ https://people.kernel.org/bleung/ On windows there are the MUTT tools, but looks cumbersome: https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/ucsi https://docs.microsoft.com/en-us/windows-hardware/drivers/us...
- MrBuddyCasino 6y agoFound a hardware thingy that can display CC1/CC2 emarker info. https://www.youtube.com/watch?v=hMlySYTHbyk https://www.youtube.com/watch?v=hMlySYTHbyk https://www.banggood.com/POWER-Z-PD3_0-QC4_0-USB-Tester-Voltage-Current-Tester-Ripple-Dual-Type-C-Meter-p-1226355.html?p=BW0420214353201307UF&cur_warehouse=CN https://www.banggood.com/POWER-Z-PD3_0-QC4_0-USB-Tester-Volt...
