I have a bunch of growth lights that need about 200mA each, so in total they'll be drawing more than 1 USB port can handle. Do I risk damaging components by using a few USB breakouts and putting their 5V and GND parallel, the way you would with batteries? The ports are all on the same dock, which runs off 110V AC.
I just want to make sure there is no similar effect like with parallel LEDs and a shared resistor - it works on paper only because you assume the LEDs are identical.
Thanks in advance.
