Nice images. Taken with an add-on for a smartphone?


Above 90 degrees centigrade seems pretty hot, but it can be OK for silicon with a maximum junction temp spec of 175 degrees C.

It's gettin hot up in heere--that's with the cover open, probably hotter when the lid is closed.

There have been over a dozen charger failures documented here, temperature and age are suspects:

Here's a visible light image showing the components that are getting hottest along the inside right wall, 3 inductors and 2 transformers, notice the heat-discoloration marks on the inside cover.

Literally smoking hot piece of cable from the looks of it.


Could be the cause of the failures.
You are correct, I believe, I didn't notice that the first time but it certainly looks like the wires made those burn marks which is more scary than the components getting hot.
