I previously discussed whether a 3-pin plug connected to a USB charger could transfer data. Most responses indicated that it couldn't, and I get that. However, I came across a mention about transmitting data through power lines. So, I'm curious: what specifically about a 3-pin plug protects me against potential vulnerabilities from public outlets compared to using a USB port? I've tried to find more details on how these plugs work for electricity and what would be required for data transfer. Thanks for your insights!

Generally, a standard charger doesn't have any built-in data transfer capabilities. So, when you plug it into a power socket, it simply delivers power without any data going through. The mention of power line communication you heard about typically involves specialized hardware that isn't present in regular chargers, hence they can't transmit data.
Just to clarify, if you're referring to a power socket, yes, data can theoretically travel over two wires by encoding it, but without the right decoding mechanism, you can't just transfer data through a standard plug. USB setups are designed for easy data transfer, while plugs are simply for power. So, no, you can't get viruses through regular plugs like you might through USB connections.
You seem to be mixing things up a bit. To send data over power lines, you'd need specific equipment like a Powerline Network Adapter. Regular chargers just don't have this capability, so you don't need to worry about data risks from a 3-pin plug to a USB charger.
Thanks for the clarification! So, the standard plug really does serve as a protective barrier no matter the cable I use, right?
