What does this USB-A / USB-C shielded cable do?

It allows safe charging while blocking any data transfer, protecting your devices from unauthorized data access in public charging environments.

Are there any limitations when using this cable?

This cable is for charging only and does not support data transfer. The USB-C version supports up to 100 W (20 V / 5 A) fast charging, while the USB-A version supports up to 15 W (5 V / 3 A).

Is it normal for the cable to get warm?

Yes. Slight warmth is normal during high-power charging. The aluminum shell and shielding help dissipate heat efficiently for safe performance.

Is there any directional issue when charging?

The USB-C cable supports two-way charging — it works both from USB-C male to female and from USB-C female to male. The USB-A cable is one-way only: plug the male end into the power source and the female end into the device.
