Put a stop to data juicing

When connected to unknown or public USB ports, the 4smarts USB Data Blocker prevents data transfer by physically cutting the data lines inside. Only power flows – no information. This effectively protects you against data theft, malware, or unwanted access, allowing you to charge your devices with peace of mind, e.g., at the airport or in hotel rooms.

Fast-charge compatible – up to 5 amps

Whether smartphone, laptop or tablet – the USB-C to USB-C adapter enables ultra-fast charging with up to 240 W. It’s compatible with standard devices and cables, supports USB4, PD 3.1, as well as Thunderbolt 3 and 4, and ensures powerful yet safe 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 the data lines disabled, your device won't display notifications, permission requests, or pop-ups when plugged in – even when connected to a computer.

Durable aluminium housing – strong and long-lasting

Its sturdy aluminium casing shields the internal components from pressure, impact, and scratches. Whether you're travelling or at the office – this adapter is built to last.

Always with you – ultra-compact, lightweight, and instantly accessible

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