USB Condom Protects Your Devices
The principle behind this piece of hardware is sound, but the name of the product could use a little tweaking.
The USB Condom does what it says; protects your plug and keeps it safe from viruses. 
The USB Condom is meant to protect against what's known as "juice jacking," where a seemingly innocuous charging station is used to steal data or harm a device.
