I purchased a UGREEN 6-in-1 USB dock to develop my 2012 Macbook Professional’s capabilities (cannot presently afford something new).
The dock has a USB-C connector to the pc, which has solely USB-A 2.0 ports, for which I am utilizing a USB-C to USB-A adapter from UGREEN too. It really works nice.
Nonetheless, I can solely join one USB system to the dock, as connecting anything makes different system connections fail; I presume it is as a result of there’s not sufficient present to maintain all related gadgets powered.
The factor is, this dock additionally has a USB-C PD enter, which may maintain related gadgets powered while offering energy to a USB-C laptop computer corresponding to trendy Mx Macbooks.
Nonetheless, sinde the 2012 Macbook Professional does not have native USB-C ports nor does it learn about USB-PD, right here comes my query:
If I related a USB-C energy provide to the dock’s USB-PD enter to maintain related gadgets powered (say, a 45W energy adapter), would this energy enter harm the USB-A connection to the laptop computer, or would the laptop computer’s USB-A ignore it?
