These two are USB-C power bricks made by ChiconyPower for HP, and are otherwise the same except for the mains cable connector. The one on the right works with the standard and common C5 connector.
The one on the left is a mistery? And is incompatible with C5 or C7.
Anyone know what the one on the left is called?
Does anyone have any idea about the pinout?
What about other uses and/or where can I get a mains lead/cable?
