4smarts USB-C auf USB-A / USB-C Datenblocker Adapter, 2er Set, schwarz

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.

Always With You – Ultra-Compact, Lightweight, and Immediately Accessible

Thanks to their slim and space-saving design, the adapters fit easily into any pocket – whether in your wallet, backpack, or next to your laptop. The adapters remain discreet, securely stored, and ready to use whenever you need them.
