Travelers Beware: Public USB Charging Stations Pose Security Risks

Public USB charging stations pose security risks for travelers, as cybercriminals can exploit them to introduce malware and monitoring software onto devices through a process known as "juice jacking."
Cyber theft has been on the rise in recent years, with Americans losing $10.3 billion to various internet scams in 2021 alone.
Alternatives to public USB charging stations include portable battery packs, solar chargers, and car chargers.
General tips for safe device charging while traveling include using personal chargers and charging cords, charging devices using regular electrical sockets, considering alternative charging options, staying informed about potential cybersecurity threats, and using a VPN when connecting to public Wi-Fi networks.
By being aware of potential security risks and taking appropriate precautions, travelers can protect their devices and personal information while keeping their devices charged and ready for use.


In today’s digital age, travelers often rely on their smartphones for various tasks, such as flight check-ins, boarding passes, ride arrangements, and in-flight entertainment.

With this increased usage, keeping devices charged becomes crucial. Many airports, hotels, and shopping centers offer free USB charging stations for this purpose.

However, the FBI has recently issued a warning against using these public USB ports, as they may expose users to cybersecurity threats.

Malware and Monitoring Software Threats

Cybercriminals have discovered ways to exploit public USB ports to introduce malware and monitoring software onto travelers’ devices.

This type of cyber attack, known as “juice jacking,” can lead to locked devices or the theft of personal data and passwords.

Criminals can then use this information to access online accounts or sell it to other bad actors.

The FBI advises using personal chargers and USB cords with electrical outlets instead of public USB ports to protect against these threats.

Regular electrical sockets are not a threat to transmit data to your phone and usually charge devices faster.

The Growing Prevalence of Cyber Theft

While no specific statistics on juice jacking are available, cyber theft has been on the rise in recent years.

According to an FBI report, Americans lost $10.3 billion to various internet scams in 2021 alone. 

The growing reliance on smartphones and other digital devices has made it increasingly important for travelers to be aware of potential security risks and take appropriate precautions.

Alternatives to Public USB Charging Stations

For those looking to avoid potential security risks, there are a few alternatives to consider:

  1. Portable Battery Packs: The Federal Aviation Administration (FAA) allows American passengers to carry up to two lithium-ion batteries with a capacity of 101-160 watt hours (Wh) per unit in carry-on luggage. These batteries can be used to charge devices during travel, as long as the appropriate charging cord is also brought along. It’s important to note that some airlines, particularly in Europe, may have stricter restrictions on the power capacity of external batteries allowed on board. Be sure to check the specific regulations for your flight before traveling.
  2. Solar Chargers: Solar-powered chargers can be a great option for charging devices while traveling, particularly for those spending time outdoors. These chargers use sunlight to generate electricity and can charge devices without the need for an electrical outlet. However, keep in mind that charging times can be longer, and weather conditions may impact the charger’s efficiency.
  3. Car Chargers: If you’re planning a road trip or renting a car during your travels, consider using a car charger to keep your devices charged. These chargers plug into your car’s cigarette lighter or USB port and can charge your devices while you’re on the go.

General Tips for Safe Device Charging While Traveling

  • Use your own charger and charging cord instead of public USB ports.
  • Charge your devices using a regular electrical socket, which does not transmit data and usually charges faster.
  • Bring a portable battery pack or consider alternative charging options, such as solar chargers and car chargers.
  • Stay informed about potential cybersecurity threats and follow official guidelines to protect your devices and personal information.
  • Consider using a VPN when connecting to public Wi-Fi networks to encrypt your data and protect your privacy.

By following these tips, travelers can minimize the risk of falling victim to cyber attacks while still keeping their devices charged and ready for use. Staying vigilant and taking necessary precautions can help ensure a safe and enjoyable travel experience.
