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.

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.

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!

Funciona el producto, con el asunto del COVID19 tardó bastante pero el vendedor responde mis dudas

Works great 👍🏻

Plug in via this gadget and you are safe. Power only, no recognition by pc or tablet that a device is connected so no data path for anyone to snoop on in public charging areas like airports or on planes. Doss what it says on the tin, couldnt be simpler.
