If you’re a frequent traveler, you’ve probably experienced running out of battery power on your smartphone. Of course, there would always be USB power plugs available in most airports, hotels, or other public places. While they offer an easy and quick way of charging your device, they can leave your smartphone vulnerable to hacking. So, in this case, do you need a USB data blocker?
In this post, we will explain the purpose of this nifty gadget. We will also teach you how to choose excellent USB data blockers.
What Are USB Data Blockers?
Funnily enough, USB data blockers are also legitimately referred to as ‘USB condoms.’ They are little devices that let you plug into USB charging ports without worrying about juice jacking. They serve as a protection against risks of infecting your smartphone or tablet with malware. They can even prevent criminals from executing or installing malicious code on your device to access your data.
Keep in mind that it can be difficult to tell if a USB power charging station is safe enough for you to plug your devices. Even wired or wireless public Internet connections can bring security risks. Of course, you can use a VPN while browsing. That said, hackers will still be able to access the data on your device if you connect it to a public charging station.
Now, if you use a USB data blocker, you’ll be able to provide adequate protection to your device even when you’re using a USB power charging station in a public place. Of course, it is always best to bring your own power bank so you can avoid using public charging stations.
How Do USB Data Blockers Work?
As we’ve mentioned, a USB data blocker can prevent hackers from infecting your devices with malware and stealing your data. Charging stations are commonly rigged by attackers, allowing them to juice jack your data. Now, a USB data blocker acts as a protective layer that prevents data pins from coming through your device. Essentially, no data will flow through your smartphone, but it will still charge as if it is plugged directly to the power charging station.
Using a USB data blocker can prevent any unwanted exchange of data when you connect your smartphone or tablet into a foreign computer or a public charging station via a USB cable.
How to Choose a USB Data Blocker?
We cannot reiterate enough how risky it would be to connect your devices to public networks without proper protection. You are essentially letting cybercriminals access your data with ease. Now that you know the dangers, always remember to be cautious when you are connecting to public Wi-Fis and charging stations.
Thankfully, USB data blockers are quite accessible and inexpensive. Moreover, their features are so basic that you do not have to tear your hair out trying to decide which one to get. That said, to make things easier for you, we’ve compiled a list of USB data blockers that are worth using.
