Q: Some USB-C to USB-A cables sold on Amazon were found to be missing this required 56K ohm resistor and bricked customer devices. Are ZMI's cables safe to use?
A: All ZMI branded USB-C to USB-A cables have the required 56K ohm resistor and are compliant with official USB specifications. Such USB-C to USB-A cables include our USB-C/Micro-USB to USB-A combo cables (they can be used as C to A when the connector adapter is engaged.). So, rest assured, all ZMI USB-C cables are safe. ZMI holds itself to a high standard and abides by official USB specifications for all of its cables.
