Double Protection
Upon first glance, this looks like a normal charger, and we probably wouldn’t give it a second thought. However, if you take a closer look, you might wonder what exactly is the purpose of this device. I mean, it looks pretty pointless. If you don’t know what device is actually used for, you would just assume that it is a sort of jacket that you plug your USB into before you plug it into a power source.
If you’ve been using this without knowing the actual use, you might have actually been saving your device from malware. This device is meant to ensure that when you hook on to something, nothing is transmitted. You run the risk of getting a virus when you connect to a computer.
