With busy travel schedules, charging phones at the airport is a convenient option for many. However, the possibility of juice jacking has raised concerns about the safety of using airport charging stations. Juice jacking is a form of cyber-theft where malware is loaded onto public USB charging stations, enabling data theft and even device locking. While there are no confirmed reports of this occurring at airport charging stations, the FBI and FCC have warned about the potential risks. To stay safe, travellers are advised to carry their own chargers and use power outlets instead of USB ports, or invest in portable chargers. Additionally, using power-only USB cables or USB data blockers can prevent data transfer while charging.

What You'll Learn
The risks of charging your phone at an airport
Charging your phone at an airport can be risky. Public charging stations, including those at airports, are vulnerable to hacking. The FBI has issued warnings about this, advising travelers to avoid using free charging stations in airports, hotels, or shopping centers.
Malware and Monitoring Software
The USB charging stations found in airports and other public places may be exploited by hackers to introduce malware and monitoring software onto your device. This is known as "juice jacking," a tactic used by cybercriminals to maliciously access electronic devices while they are charging. Malware installed through a corrupted USB port can lock your device or export personal data and passwords directly to the perpetrator. Criminals can then use this information to access your online accounts or sell it to other malicious actors.
Preventing Data Theft
To prevent data theft and malware attacks, you can take several precautions when charging your phone at an airport:
- Use an AC power outlet instead of a USB charging station. Bring your own charger and USB cable, and plug into an electrical outlet.
- Carry a portable charger or external battery to avoid relying on public charging stations.
- Use a charging-only cable, also known as a power-only USB cable, which prevents data transfer while charging. These cables are designed to only transfer power from the charging station to your device, blocking any potential path for malware.
- If you must use a public USB charging station, always select "charge only" if given the option to "share data" or "trust this computer."
- Install antivirus software on your device and regularly scan for and delete any suspicious apps.

How to prevent data theft at airport charging stations
Public charging stations, including those at airports, can be risky. The practice of data theft at these charging stations is called "juice jacking," where criminals load malware onto charging stations or cables they leave plugged in at the stations. This can result in the theft of personal data, passwords, and business logins, which can then be used to access online accounts or sell them to other bad actors.
- Use power outlets: Avoid using USB charging stations altogether and opt for power outlets instead. Bring your own charger and USB cord to connect to an electrical outlet.
- Use a power-only USB cable: If you must use a USB charging station, use a power-only USB cable. These cables are designed to only transfer power and not data, preventing any potential malware from reaching your device.
- Use a USB data blocker: Connect a USB data blocker, such as the Juice-Jack Defender or the PortaPow USB Data Blocker, to block any data transfer while allowing your device to charge.
- Avoid public Wi-Fi: Avoid using public Wi-Fi networks, as they can be targeted by cybercriminals. Use your own mobile data connection or a VPN for added security.
- Carry a portable charger: Invest in a portable power bank or a power pack that runs on AA batteries to charge your devices on the go without relying on public charging stations.
- Be cautious of prompts: If you plug your device into a USB charging station and a prompt appears asking about data sharing, always select "charge only."
By following these precautions, you can help protect your data and devices from potential threats at airport charging stations.

What is 'juice jacking' and how to avoid it
Public charging stations, such as those found in airports, hotels, and malls, can be risky. While they are convenient, they can also be a hotbed for cyber-attacks, including "juice jacking".
Juice jacking is a type of cyber-attack where bad actors load malware onto public USB charging stations to access and infect electronic devices. This malware can lock a device or export personal data and passwords directly to the perpetrator. Criminals can then use this information to access online accounts or sell it to other malicious actors.
Although juice jacking has been proven to be technically possible, there are no confirmed reports of it occurring. However, it is still important to take precautions to protect yourself from potential attacks.
- Use power outlets instead of USB charging ports to charge your devices. Carry your own charger and USB cord and use an electrical outlet.
- If you must use a USB charging station, use a power-only USB cable or a USB data blocker, such as the Juice-Jack Defender or the PortaPow USB Data Blocker. These cables and blockers prevent data transfer while still allowing your device to charge.
- Carry an external battery or a portable charger so you don't have to rely on public charging stations.
- If you plug your device into a USB port and a prompt appears asking you to select "share data" or "trust this computer," always select “charge only.”
- Avoid using public Wi-Fi networks, as these can also be used by cybercriminals to target travelers.

Wireless charging at airports
However, it's important to be cautious when using public charging stations, as there are potential risks associated with them. According to sources, cybercriminals can manipulate public USB ports to access your device's data. This type of cyber-attack, known as "juice jacking," poses a significant threat, as there is no limit to the information a hacker can obtain. To prevent data theft, travelers can use power-only USB cables or USB data blockers, which allow charging without enabling data transfer.
Some airports have started adopting wireless charging technology to enhance the passenger experience. Wireless charging offers several advantages, including convenience and faster charging. Additionally, wireless charging eliminates the need for travelers to carry extra cables, reducing clutter and the risk of leaving them behind.
To wirelessly charge a device, wireless charging accessories such as charging pads or mats are used. These accessories utilize magnetic induction or technologies like Apple's MagSafe to efficiently charge devices without the need for cables. However, it's important to ensure that there are no objects, especially metal or magnetic cases, between the device and the charger, as they can interfere with the charging process or damage sensitive items like credit cards or passports.
Overall, wireless charging at airports offers a safe and convenient way for travelers to charge their devices on the go. By investing in wireless charging solutions, airports can provide an invaluable service to passengers, ensuring their devices stay powered up during their journey.

Portable chargers as an alternative
While charging your phone at the airport is possible, it may not always be the safest option. Public charging stations, including those at airports, are susceptible to hacking and malware attacks. This means that your personal data may be at risk when you use these stations.
Portable chargers offer a convenient and safe alternative to charging your phone at airport charging stations. They provide peace of mind and freedom from the constant search for an outlet, especially when travelling. Portable chargers are compact, lightweight, and can fit into your pocket or bag, making them easily accessible at all times.
When choosing a portable charger, there are a few factors to consider. Firstly, opt for chargers with built-in fast-charging capabilities and those that are small and lightweight. For instance, the Calpak portable charger is highly recommended for its compact size and functionality. Another popular option is the Veger power bank, which is discreet, simple, and easy to use.
Additionally, ensure that your portable charger is compatible with your device. Some power banks, like the one mentioned by Kat Chen, only work with specific iPhone models. It is also important to note that portable chargers containing lithium-ion batteries must be packed in carry-on bags and are prohibited in checked luggage, according to TSA guidelines.
By investing in a portable charger, you can ensure that your phone stays charged while avoiding the potential risks associated with public charging stations.
