> Phone chargers have no power LEDs and we are fine. I have a white anker charger with a blue (of course, it's always blue) LED so bright that I had to wrap the entire brick in light-blocking tape because the LED phased through the case everywhere. Another favorite of mine was an USB M.2 enclosure that of course also had a blue LED (constant on = on, blinking = activity), but instead of using a side-emitting LED they used a top-emitting LED and just made it so incredibly bright that the light leaking out the side was still bright when viewed from outside the case. When you removed the case it was blindingly bright even in a well-lit room. Probably used more power than the USB chipset. Almost surprised you couldn't see it through the aluminium case.
