Frequently Asked Questions

Q: What is a USB data blocker and how does it work?

A: A USB data blocker is a small adapter that sits between your charging cable and a USB port. It physically disconnects the data pins inside the connector so that only the power pins remain active. This means your device charges normally, but no data can be transmitted or received — keeping your files and information protected.

Q: Will a USB data blocker slow down my charging speed?

A: No. The data blocker passes power through without restriction. Model 1 (Type-C to Type-C) supports up to 140W PD fast charging, and all other models support up to 10W (5V @ 2A), matching standard USB charging speeds for phones and tablets.

Q: Which model should I choose for my smartphone?

A: It depends on your cable and port. If your phone uses a USB-C cable and you're plugging into a USB-A port, choose Model 2 (USB-A Female to Type-C Male). If both your cable and port are USB-C, go with Model 1. Check your device's charging port and your cable's connector types to pick the right fit.

Q: Is this device compatible with all USB-charged devices?

A: Yes — the USB data blocker is universally compatible with any device that charges via USB, including smartphones, tablets, earbuds, smartwatches, and laptops (Model 1 for high-wattage laptop charging). It works with any brand or operating system.
