Not really bad if you use a power-only cable. If the data pins aren't even wired up, can't move anything other than power.
Not sure if that works with USB-C at anything other than legacy 500mA power draw though, probably not since the device can't communicate for what it supports.
Or a USB condom. But I never really hear about those anymore.
Until you find that person who wired a 48v USB plug, just for you.
USB-PD standards push 50v. Go with wall voltage (110-220v 60/50hz) to be sure.
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.
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.
Some things are but the labelling is stupid and tiny. Many laptop ports are labeled but people aren't familiar with the icons (and the icons are often confusingly similar)
Happy Cakeday! 🍰🎂
Well--to bring it back to the security point, you can't trust the icon on the port anyway. You need a well-labeled cable, and, good luck
If your device has good software, it will only allow power unless you authorize a data connection.
* Assuming there is no bug, zero-day, or other vulnerability on the current version of your fully updated device.
Having a power-only cable removes that as a possibility.
Still gotta worry about stuff that could send a ton of current to fry the ports too. USB condoms can help here too but your own power adapter is best.
Nah, I won't worry about such problems until there is a chance of it actually happening.
Ton of voltage. You push voltage and pull current.
I only push imperial current electron flow style.
A power only USB-C cable is a violation of USB spec, has to be USB 2.0 at the least.
That's never stopped companies from making something, like A to A USB cables.
