My parents are going on holiday in a few months. They are still very bad with technology especially my dad is addicted to youtube like a kid. I fear he's going to be tempted to use the charging ports at the airport or in malls.

Do these 'data blockers' work and do the trick?

Yeah I just read about them on reddit. Apparently you can get these adapters or a whole cable that only allows the power through and doesn't have the capacity to transfer data.

USB charging ports at an airport? I'm confused on how data can be transferred through a charge. Serious question.

some of the pins are used for power, some for data. if you cut off the data pins you wont get data. some usb cables are like this by default.

I really don't. I've never taken something like that out traveling.

I know charge only cables are a thing, but I'm not sure if they would be able to fast charge at all?

Hopefully someone who knows more can help

I can't see there being any real danger in plugging into a public charge port. You have to manually approve any transfer of data when you plug your phone in. Even if it's a device you've connected a million times before. And if you're really paranoid about this, use an AC adapter instead.

Really any usb condom should work. If you already have charge cables you like you'd be better off getting the dongle only one rather then cable types like you posted. I use the jsaux one whenever I need to use a public port.

There are actually multiple ways to bypass that confirmation.

I'd recommend getting magnetic cables.
They're useful outside of the "airport" scenario, and saves wear on the usb sockets anyway.
https://www.amazon.com/dp/B08F7586NK

They don't have to be that specific brand, but they do need to be the simple "circle and nub" two-connector type if you want just power. Magnetic data cables do exist, but they aren't what you're looking for here.

They won't.
Fast charging needs power-negotiation, over the data lines.

Yeah, it's been demonstrated as technically possible, but the FCC doesn't know of any real cases of it happening in the wild.

If you approve "transfer files to 'totally not a hacker, bro'?" at the airport, that's on you.

so they are basically janky power-only usb cables

"Mitigation by hardware[edit]
Juice jacking is not possible if a device is charged via a trusted AC adapter or battery backup device, or if using a USB cable with only power wires. For USB cables with data wires, a USB data blocker (sometimes called a USB condom)[24] can be connected between device and charging port to disallow a data connection."

but yeah any modern smartphone has been patched for this like 10 years ago. snake oil.

It is obviously a crew of thieves driving tricked out street racing cars, that hijack juice delivery trucks.

Ive never seen it myself but it would require a man in the middle device placed by the hacker. Like how at ATMs they can fit a fake keypad on which records your PIN code and you never know cause it looks like a normal keypad.

in the wall wherever the charger is there could be a device that is reading via USB. Theoretically. I know theres USB devices that overload the power supply and brick whatever they plug into, as in physically destroyed, but I havent seen one where it steals all your data simply by being plugged in. Its not impossible though

This is yet another reason why all those fast food apps are dangerous.
All a hacker is going to get out of my phone is photos of beer, and a bunch of Rick Astley albums.
