Basically I’m trying to de-clutter the cables to my charging station, and was hoping to use a 3-way cable for my phone, watch, and headphones.
My main concern is if one device is able to successfully negotiate QuickCharge or PD, would that send 9-20 volts to the other devices?
e.g. if I grabbed the wrong cord and hooked it into my laptop, the laptop requests 20v, would that PD negotiation succeed and also send 20v to my 5v devices on the other two leads?
I’ve only used these kinds of cables with USB-A and chargers that can only output 5V. Most of my chargers now are QC/PD so I’m curious if I should avoid those or take any particular precautions.
Might be worth looking at a charging dock, ie:

Especially as more devices start utilizing Qi2 wireless charging with magnets. Otherwise for non-iPhone devices you need something like a magnet ring or the wonderful Snap 4 Luxe to utilize a magnetized wireless charging stand.
I have this awesome Anker one on my nightstand and it charges my iPhone, Apple Watch, and Jabra earbuds. There are cheaper options, but this one let me charge the watch at it’s highest speed.
