Frequently Asked Questions
Q: How does a USB data blocker prevent juice jacking?
A: The USB data blocker physically disconnects the data pins inside the adapter, leaving only the power pins connected. This means electricity flows to charge your device, but no data signals can travel in either direction — protecting you from unauthorized data access when using public or shared USB charging ports.
Q: Will using a USB data blocker slow down my charging speed?
A: No. The adapter is designed to automatically negotiate with the power source and support both standard and fast-charging protocols. Your charging speed is maintained while data transfer is completely blocked.
Q: Is this compatible with both Type-C and USB-A devices?
A: Yes! The data blocker is available in Type-C to Type-C and USB-A to USB-A configurations, making it compatible with a wide range of modern smartphones, tablets, laptops, and other USB-powered electronics.
Q: Is the USB data blocker RoHS certified?
A: Yes, this adapter is RoHS compliant, meaning it meets regulations restricting the use of hazardous substances in electronic and electrical equipment.
