PortaPow Transparent USB Data Blocker - Protect Against Juice Jacking

Authentique bloqueur de données. La transparence permet de voir aussi que seuls sont présents les fils d'alimentation , donc aucun vol de données. Je recommande vivement.

If you are still not sure about the product, I can safely say it works. It's a data blocker. Adapter which only lets through the power, but no data. Don't buy it and then complain how your devices cannot connect. It is literally made to block any data from going through. It's not immediately visible on product photos, but have a look at the attached picture. Red arrow points at a small window where you can see that only power pins are there, and data pins are completely missing. Green arrow shows that on the other side (where you usually connect your devices to charge) data pins are soldered together. To many devices this is a clear signal that the connected accessory is a pure charger, so they don't even attempt data connections. Physical quality is also very good. Everything seems solid and very well made. From few seconds of googling, I can see it's a small UK based company which makes these for many years already. That gave me confidence to order, but when the product arrived, I did my own measurements which only proved what's already obvious through the transparent casing. Top item - does exactly what it says. I'd be happy to buy again, but I don't need more :)

比較的小さく、デザインセンスも良い。 端子の強度は十分で、使用中に外れたりはしなさそう。

work as advertised

Fantástico. Ahora sí que cargo el smartphone de manera segura.
