If your device has good software, it will only allow power unless you authorize a data connection.

Now if only usb cables were labeled like Ethernet cables.

It amazes me how given the complexity of the USB specifications, where everything looks the same but it is not the same, nothing is ever labeled.

A power only USB-C cable is a violation of USB spec, has to be USB 2.0 at the least.

With this arrangement, they probably can't steal your data. But they can absolutely destroy your phone with a string electric shock, if that's the sort of malicious plan they have.

Until you find that person who wired a 48v USB plug, just for you.

Not really bad if you use a power-only cable.

Or a USB condom. But I never really hear about those anymore.

But I have seen multiple phones get harmed by a really bad charger. Although these chargers were not for public use.

Still, it's not a bad idea to bring a power bank. And then charge that, if you need to.

At least that's what the juice jackers want us to think.

Except that isn't even safe, just paranoid. Sometimes accidents happen because you're trying to prevent accidents

And don't travel by plane, and don't travel at all. Build a bomb shelter basement with titanium walls.
