Cayin C9 - Portable Amp

Thats good clarification! And tbh, actualy make sense since most usb chargers don’t have legit grounding.

EDIT: cayin, if you are reading this, a wall wart battery tray would be an awesome add on.

Edit2: and in the second version yall should realy include a battery bypass switch. Kind of surprised it doesn’t already have one tbh


Agreed, but also it would be super nice if they put the battery meter somewhere where it can be seen from the front of the unit if there are so many overcharging/undercharging issues.
