RUXELY USB Data Blocker Adapter 3-Pack,Protect Against Juice Jacking

These are good quality with robust cables. There are 3 in the pack. They have a male and female connector so that you can plug in your normal cable. I did not know that you could get USB cables that charged only and did not transfer data. Therefore good for security when you use the free charging points on buses and in airports etc. You just do not know what you are plugging into. I have used them in my car to check that the phone does not connect while charging.

Works perfectly, have a dashcam plugged into the cars rear USB port and the car kept trying to connect to the camera. Since fitting one of these, it no longer tries to connect to the camera, so the data isolation works fine

Now I can safely charge phone in airports, cafe, train, etc. without worry of losing personal data as possible with a tampered charging port! Criminals are the losers here and consumer might enjoy technology.

These are short USB A-A extension cables with only power pins so it is impossible for any data to pass. This is useful in the very unlikely case of some malicious device but better safe than sorry if you only need to charge. There is actually another good and more practical reason to use these in that they prevent wear and stress on the USB outlet. I have some fixed USB outlets that have failed due to repeated connection/disconnection/devices hanging off it and causing stress. Fitting these to the the fixed outlet and leaving them there moves the wear from the fixed and potentially expensive outlet to the cheap and disposable extension cable. Very useful.

I bought these as my 2015 Audi TT wouldn’t charge my phone without also trying to use it as the media input. This meant every time it disabled Bluetooth. These work great, and now mean I can charge my phone and use Bluetooth at the same time!

Great 👍

No way of knowing if it is actually working unless you happen to work in an electronic lab, which I don't.

Loved the concept of being able to charge phone laptop etc in public places knowing that no possibility of your data being read whilst charging. This is simply done by the manufacturer leaving out the data reading wiring and just leaving wiring necessary for charging. Great for holiday hotel rooms etc. must have travel item to help keep data secure.

Super hochwertig (besser als erwartet). Die Kabel sind mit Kunststofffasern umflochten und dadurch sehr robust (wie ein Seil). !Achtung Ladegeschwindigkeit! Das Kabel drosselt die Ladegeschwindigkeit auf ca. 4W (kein Schnellladen).

Ça fonctionne, le courant passe mais impossible d'accéder aux données, Parfait.

Works well for charging and no data connection. I like this better than a straight dongle as it doesn't add stress to the connector/device. Charging will be slow because the device can't negotiate a higher charging rate (no data connection!), but if you can accept that this is a good deal.

El accesorio tiene un volumen adecuado,y funciona muy bien,solo deja cargar,y no hay transmisión de datos en la conexión,va genial.

Cavetti perfetti per evitare il passaggio di dati, o peggio, di installazione di malware sul proprio telefono quando collegato ad una fonte di alimentazione comune e quindi non sicura (ad esempio in aeroporto). Funzionano ottimamente, consiglio l’acquisto.
