I have a car charger for my smartphone. It has a standard USB port and a USB-C one. It has Qualcomm Quick Charge 3.0. The USB-C port basically worked once, now it will not charge devices. Tried multiple cables and multiple devices, no luck. The standard USB port works perfectly. I opened it up and found 3 little things that almost look like fuses which are reddish orange and blue, one of which looks almost like it exploded (see photos). It also looks somewhat discolored. I won it in a giveaway online, and their warranty service said they can only replace it with copy of original receipt.
I tested all 3 for resistance and got about 9 ohms in the damaged-looking one, and no continuity on the other two. Any ideas what this is?
