USB Data Blocker – Safe Charge Anti Juice Jacking Adapter for Public USB Ports – Blocks Data Transfer, Stops Malware & Hacking, Protects Phone & Tablet – Secure Charging – 1 Pack

Excellent for airport, still use VPN

It works as advertised and is small so no great burden to carry while traveling or even out and about during our daily routine. I tested it out by installing it between my smart fitness watch and my laptop and while it would charge my watch, it would not sync my watch’s data with its app installed on my laptop. Considering it was made in Germany, the $9.99 price was amazingly reasonable. I bought two so both my husband and I can charge our devices while traveling and be assured our data is safe.

Very good construction & seems to work well. Little higher price than China-made devices but have more confidence in German-made security device.

Still traveling and using it

I do like it d/t easy to use and I trust it

Arrived much quicker than anticipated, looks good and works good.

Un excelente producto para brindar seguridad a nuestras cargas de puertos usb, de locales, aeropuertos, etc. recomendado.

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.

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

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
