Has anyone looked into data blockers such as “PortaPow” on Amazon.com? If they’re a scam that’s fine, but I will never forgive myself if they turn out to be loaded with exploits...

Also can anyone comment on how feasible defenses are against outlet power hacking at say a hotel? Is there any tool under $100 available to the masses? $200?

If the budget is $100, then bringing a compact mains charger seems easiest. E.g. https://www.themu.co.uk/collections/collection/products/amer...

Not to mention most people are likely to have a drawer full of the things from past phones.

Portapow stuff is fine.

Hotels supply mains power. The parts of your computer that deal with data are well separated from the parts that deal with hundreds of volts.
