5 Best USB Data Blockers in 2021 You Should Try
We take great care to protect the information on our phones and laptops. Using a simple VPN service when browsing the internet, or changing our master passwords on a regular basis, are just a few examples. But what if you leave your phone to charge in a public place like your local coffee shop or an airport charging station? Yes, juice jacking is a real thing, and hackers can use your phone’s USB port to infect it with harmful software. I must say, it’s a little frightening. But, thanks to gadgets like USB data blockers, this isn’t a problem.
A USB data blocker is based on a basic concept. These items disable the data pins on your charging cable’s USB port. This prevents the possibility of data leakage from your phone. In a nutshell, it serves as a barrier between your phone and a (public) USB port.
The good news is that most USB data blockers are small enough to put into your purse or wallet. Simply connect the USB Type-A end of this gadget to the USB Type-A end of your phone, and that’s it. It’s been dubbed the USB condom by some. No, I’m not making a joke.
So, if you’re looking for a good USB data blocker for your phone, here are a few of the greatest options.
1. PortaPow USB Data Blocker 3rd Gen
The PortaPow 3rd Gen USB Data Blocker has a maximum power output of 2.4 Amps.
There are a lot of satisfied customers. Because the device only supports 2.4A charging, you won’t get the same charging speed on your smartphone as you would ordinarily.
A USB-C data blocker is also available if that’s what you’re looking for. The functions are identical, except that instead of a USB-A head, you get a modern USB Type-C head.
2. Pure USB Data Blocker by PortaPow
The good news is that its transparency does not compromise its durability.
You might also want to look into PortaPow’s cable, which has a built-in data blocker. It’s 3.3 feet long and ends with a normal USB-C port.
3. USB-MC1 pluggable
The USB-MC1 from Plugable has received a lot of positive feedback from its consumers. The general consensus is that it performs just as described.
The device’s only constraint is that it can only draw 1A of electricity. As a result, even if you plug into a port that can give 2.1A of power, it will still mimic a 1A current and charge your device slowly.
4. Data Blocker USB Defender
At the same time, the item is long-lasting and will serve you well. It does exactly what it says it will.
5. ET Cell Phone USB Data Blocker
It has the ability to charge quickly. This unit has gotten a lot of positive feedback so far.
The product’s breadth, on the other hand, is a touch cumbersome, and it may restrict you from using the surrounding USB ports on desktops and laptops.
Travel with caution.
Though USB data blockers are a good way to prevent data and other information from being stolen from your phone, the best alternative is to travel with a power bank (see what to look for before buying a power bank). You won’t have to wait in line at a charging station this way. It’s also safe, and the portability is the icing on the cake.
