Hi there
![Smiley :)](https://www.eevblog.com/forum/Smileys/default/xsmiley.gif.pagespeed.ic.R8GFI-pF6f.png)
I have a Choetech Desktop 6 USB Charger, witch two of the ports are Quick Charge 2.0
I was charging my 15000 mAh powerbank, after some time the Quick Charge 2 started to be some unstable (come and go). I did hear something who sounded like coil whine.
Then i continue the charge in my regular wall adapter, no problem there. So there is now a problem with the 6 port USB Charger.
I later tested the 6 port USB Charger with a usb voltmeter, it can now only deliver about 2-3W instead of 15W.
The other Quick Charge port work as normal.
So i tear it apart and notice 3 caps that dont look so fresh lol

are this typical sign of blown caps or just "glue" brown "gunk"?
Them are marked :
h-cap 15uf 400v Low esr.
I have googled h-cap but not much help.
