Lockdown mode in Android 15 protects your phone from 'juice jacking'
androidauthority.com
Points taken from article:
- Android 15 is adding a built-in mechanism to protect your device from “juice jacking” attacks.
- Charging will be allowed when lockdown mode is enabled in Android 15, but USB data access will not.
- Juice jacking is a largely theoretical problem you don’t really need to worry about, but it’s still nice that Android will protect you against it.

You certainly don't want anyone jacking your juice without permission.
That’s why I use a USB condom.
Just in case you are joking (or people think you are) those do exist. Basically a dongle with only the power pins on each end.
This is only useful if you're not using your own cable. Otherwise you can simply use a "power only" cable.
But better use the condom dongle for only $59 !
5.49€ for a USB-C to USB-C condom, and I can't even find a USB-C charge only cable.
Personally, I plug a power bank into the public port and charge my other devices through it. But if an AC outlet is available, that's all moot anyway.
Your devices will charge slowly or potentially not at all
There are some that do power negotiation on the input side, and then power negotiation on the output side so you can have your cake and firewall it too.
