Stop Data Leakage

The 4smarts USB Data Blocker prevents data transfer when connected to unknown or public USB ports by physically interrupting the data lines. Only power flows – no information. This effectively protects you from data theft, malware, or unauthorized access, allowing you to charge your devices worry-free, for example, at airports or in hotel rooms.

Fast Charging Compatible – Up to 5 Amperes

Whether it's a smartphone, laptop, or tablet – the USB-C to USB-C adapter enables ultra-fast charging of up to 240 W. It is compatible with standard devices and cables, supports USB4, PD 3.1, as well as Thunderbolt 3 and 4, ensuring powerful and secure energy transfer. The USB-C to USB-A adapter delivers up to 15 W – perfect for older devices with lower power requirements, such as headphones, smartwatches, or fitness trackers.

No Pop-up Warnings – Just Power, No Prompts

With disabled data lines, your device will not display notifications, permission requests, or pop-ups when connected – even when connected to a computer.

Robust Aluminum Housing – Strong and Durable

The sturdy aluminum housing protects the internal components from pressure, shocks, and scratches. Whether traveling or in the office – this adapter is built for durability.
