USB condom: Safe charging at external USB ports

Whether at the airport, in the coworking space, at the conference or in the hotel room: There are public USB ports for charging the battery for smartphones, tablets and the like. But is that always just electricity that flows from A to B, or isn't data also drawn from B to A? If you want to make sure that no data is tapped and copied from your mobile phone while charging your smartphone, you can use a special adapter. In the following I have summarized where you can get this no-data adapter and how it works.

The PortaPow SmartCharge adapter serves as a USB condom for safe charging without data exchange. Ideal for airports, hostels, conferences and third-party computers.

The PortaPow data block USB adapter is used to ensure that no data is transmitted when charging. In addition, the charging speed can be increased using the SmartCharge chip. In addition, USB ports can also be used to charge cell phones or power banks that are not intended for this purpose - for example the USB port on the hotel television.

Charge faster thanks to the adapter on the charging cable

According to the manufacturer, the "PortaPow Data Block USB Adapter" not only offers anonymity when charging on public ports or on other people's computers, but also delivers faster charging times. Hence the name “SmartCharge”. The PortaPow SmartCharge chip, as stated in the product description, should automatically recognize the correct Apple or Android charging specification and thus achieve the fastest possible charging speed. A good extra for disabling data transfer mode. According to the manufacturer, the item is compatible with all Apple iPhone and Apple iPad models as well as micro USB devices such as Android smartphones and tablets.

This is how deactivating data transfer mode works

But how does this little plug realize that charging is as fast as possible, but that no data can be queried from the device? Quite simply: the contacts that are necessary for the transfer of data are missing. A regular USB plug for data exchange, electrical power and the like has four contacts - two outer contacts for the electrical operation of the connected device or medium; and two inner ones for digital information. 

How is data exchange via USB prevented with this connector? Quite simply: the necessary contacts are missing. This means that the protection cannot be deactivated by outside interference!

The inside is missing, so that the manipulated charging port or the third-party computer can be equipped with software no matter how tricky it is. Contacts, pictures, videos, e-mails and the like are not spied on thanks to this connector. In this way, this little helper becomes a data blocker, ready to use anywhere and anytime, and secures your anonymity and your device against data theft. What do you think?
