Three crucial reasons why you should never charge your phone at the airport, according to a security expert

It's very convenient, but questions have been raised on security with charging at airports
While charging your phone at the airport may seem like a practical decision, especially before boarding a flight, one security expert is urging travelers to think again.
With mobile devices now essential for accessing boarding passes and staying entertained during long flights — whether by streaming shows or listening to podcasts — keeping your phone fully charged feels like a no-brainer.
Most modern airports are equipped with charging stations, offering travelers a convenient way to top up their batteries. But according to Jae Ro, a security specialist from plug adapter company SIGNAL + POWER, that convenience comes with serious cybersecurity risks.

“Those public USB ports can be manipulated to install malicious software on your phone,” Ro told MailOnline.

He explained that once malware has been planted on your device, it can operate in the background without detection — stealing sensitive data such as passwords, login credentials, or banking details.
The Hidden Threat: Juice Jacking
One of the primary concerns is a cyberattack method known as "juice jacking."
Through this tactic, hackers load malware into public USB ports. When an unsuspecting traveler plugs in, the malware can hijack their device — locking them out or silently transferring personal data and passwords to the attacker.
Because smartphones use the same port for both charging and data transfer, plugging in your phone can unintentionally open the door to remote access.

“Once compromised, your phone isn’t just vulnerable at the airport — the threat travels with you,” Ro warned.

Even Untampered Ports Aren’t Safe
Ro also cautions that even ports that haven’t been deliberately corrupted can pose risks.
Charging stations are capable of transferring both power and data. While many smartphones ask users to choose between “charging only” or “data transfer,” Ro says this security feature can be easily bypassed by rogue charging hubs.

“Your device could still be exposed to data leaks or unauthorized access,” he added. “The stolen information might later be exploited for identity theft or sold on the dark web.”

Official Warning from the FBI
This isn’t just a theoretical risk. In 2024, the FBI issued a public advisory urging people to steer clear of free public charging stations — including those in airports, hotels, and shopping malls.
A notice on the FBI’s website reads:

“Avoid using free charging stations in airports, hotels, or shopping centres.”

To stay protected, experts recommend using your own power bank, a wall charger, or a USB data-blocker — a device that allows electricity to flow while blocking data transmission.
In today’s world, staying charged is essential — but keeping your personal information secure is even more important.
