Verifying USB-C voltage I have heard about some USB-C chargers frying tablets, phones, etc. If I ordered a generic charger online for price reasons, how can I can verify its voltage before using it with my Android devices?
There exists an Android app for this purpose called "USBCheck":

Unfortunately it is currently only supporting Nexus 5X and Nexus 6P.
