Review: The Databloc Hacker-Safe USB Adapter from Eyebloc

It might seem counterintuitive, but you should consider adding something to your travel kit that stops certain device functions. Specifically, the Databloc ($17.95) that Eyebloc sent me to try. The concept of the device is simple: it's a USB adapter that you add to the USB cable you normally travel with. The other end of the cable is either USB-A or USB-C depending on what you order. So what does this do, other than add an inch to your cable and convert a USB-A to USB-C if needed? It removes the data transfer functionality. Put simply, it's like a firewall that you don't even have to think about.


Free charging stations are great, but there's a chance they could be corrupted with malware by individuals with bad intentions. You might not think twice about tapping the "Trust this computer" warning that pops up the first time you plug in your iPhone to a new computer, especially if you think you are only plugging in to a power source at an airport or coffee shop. But this is a security risk. Databloc avoids this altogether by turning your data transfer cable into a power-only cable. And when you want to plug in to a trusted computer, you just remove the Databloc from the USB-A end. It's simple and powerful.


The Databloc is sold in packs of two, 20, or 100 and in white or black. Personally, I would like to see a distinguishing color like red, yellow, or orange so I could easily find it and know my data is protected when it's in use. It might also be nice if they had a rubber clip or mechanism to attach it to a regular cable, similar to some cables that come with USB-C, Lightning, and microUSB tips, so it doesn't get lost when not in use.
