"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."
"Just the right lengths There are three sizes of cables: the that's perfect for general charging, a that I find just the right length for use with a laptop, and a 5-pack of 15cm/6in cables that are great for charging small devices. No data lines These cables all feature an and allow charging up to 240W (48V/5A), but because they don't have any data lines, any attempt at communication between the charger and the device being charged is blocked."
USB-C ports provide both power and data, which creates a risk of juice jacking when charging from untrusted public sources. Data-blocking USB-C cables remove data lines and permit charging up to 240W (48V/5A) while blocking any communication between charger and device. These cables are available in multiple lengths including 1m, laptop-length, and short 15cm/6in packs to suit different needs. Distinguishing features include a red strain relief and a tag showing specs and data-blocking capability. Data-blocking dongles are an alternative for users who sometimes need data functionality. Public chargers at airports and transit pose the greatest risk.
