"We're so used to using USB-C for charging that we forget it's also a fully featured data port, and hackers can use people's desperation to find a charger for their phone or laptop to their advantage. Juice jacking is a real threat -- but, fortunately, it's quite easy to protect against it with the right equipment. Also: 7 hacking tools that look harmless but can do real damage Plugable of that allow you to charge your devices while blocking data."
"The cables are well built and distinguishable from your other cables by the red strain relief (remember the mantra -- red means power only!) and the tag that gives the specs and highlights that they are data blockers. I find data-blocking cables more convenient than the little data-blocking dongles because it's easy to overlook those (although they do allow you the option of using your cables for data if you need to, so they might work better for some people)."
USB-C ports carry both power and data, creating a risk of juice jacking when using unfamiliar public chargers. Data-blocking USB-C cables remove data lines while supporting high-power charging, preventing any communication between charger and device. Plugable offers cables in multiple lengths, including 15cm/6in packs for small devices, and supports charging up to 240W (48V/5A). The cables are marked with red strain relief and spec tags to indicate power-only use. Data-blocking cables are often more convenient than dongles, and are most useful for frequent travelers who charge at airports, trains, buses, or public kiosks.
