USB Data Blocker – Sync Blocker for Secure Charging, Protection Against Data Theft & Malware, USB Security Adapter for Smartphone, Tablet & Laptop – White

I have a Garmin satnav, and a convenient USB port in my van. however the Garmin assumes its a computer and enters communications mode, the van radio reckons its a USB memory stick and wants to play music. This in between allows both to coexist, Radio no longer cares, and Garmin knows something is odd, as it does try to comminicate, but then boots up properly and charges. There is a funky cable that does same job BUT its far too long and difficult to source in the UK

I was skeptical about this actually working, BUT it does exactly what it’s meant to do, I tested it out on my laptop and home computer and it DEFINITELY works! Great purchase and would recommend to anyone who wants to keep the content of their phone or usb attached device private and/or less likely to be unknowingly copied!

Finally feel free to charge my phone at public facilities, airports and trains. I tested it first by using it to plug one of my USB pen-drives into my laptop and indeed it could not be read! This is a great little device, very stylish, compact and a must have! Also, makes an excellent gift. Stay safe out there …

With this device, my laptop can't 'see' inside the phone. It's a very good choice. In this nowadays this device is a "must to have it".

Seems to work fantastic does what it says on the tin. Very pleased.

Used the product for my phone and happy to charge it at public charging point without worrying whether my data is being used.

Good product.

Fonctionne très bien, j’en suis satisfait.

He probado a conectar mi smartphone al portátil con el cable USB a través del bloqueador y efectívamente no deja transmitir datos. Deduzco por tanto que funciona correctamente y dado que lo elegí para eso y tiene un buen diseño compacto, estoy muy satisfecho con mi compra.

... importantly, not made somewhere inclined to installing 'backdoors' into your devices. Support European, American, and Canadian business!

Der Previse USB-Datenblocker verhindert nicht nur den Datenaustausch mit einem angesteckten USB-Endgerät - er sorgt auch dafür, dass der USB-Anschluss als solcher gar nicht erst erkannt wird. Beispiel: Mein Garmin-Navigationsgerät (DriveSmart 65) will mit einem normalen USB-Kabel (Nicht-Garmin) an einem USB-Ladegerät oder auch an der USB-Buchse im Auto immer in den PC-Übertragungsmodus schalten - was absolut nervt! Ist der Previse-Datenblocker dazwischengeschaltet, fährt das Navi ganz normal im Navigationsmodus hoch, wie mit dem originalen Garmin-Ladekabel (über die 12V Zigarettenanzünder-Buchse). Der USB-Anschluss wird hier also nicht erkannt - so soll es sein! Ich hatte mir zur Sicherheit noch den "PortaPow" USB-Datenblocker mitbestellt, der für diesen Zweck leider überhaupt nichts taugt - der USB-Port wird vom Navi weiterhin erkannt! Für die reine Ladefunktion eines gängigen Smartphones mag der "PortaPow" ja Ok sein, was allerdings in meinem Fall nichts nützt. Fazit: Wie man sieht, ist Datenblocker nicht gleich Datenblocker!

Perfettamente conforme alla descrizione e funzionante: fa passare solo la corrente bloccando la parte dati e permette quindi la ricarica senza la possibilità di accedere al contenuto del telefono tenendolo quindi al riparo di furto dati e virus. A mio parere indispensabile da usare se si viaggia e si connette il cavo usb del telefono a caricatori sconosciuti!
