The Hidden Dangers of Public Charging Stations: Protecting Your Device and Data

As the world becomes increasingly reliant on smartphones, it has become almost second-nature to pack a charger, everywhere we go, just in case our precious devices lose power. However, there are times when we DO forget our chargers, and are forced to seek out public charging-stations. While this may seem like a convenient solution, it actually poses a significant risk to both the security and the health of your device.

On April 6, 2023, the Denver office of the FBI sent a notice on Twitter regarding the usage of free charging-stations ( They warn that using these stations can open you up to malicious environments. This sounds very urgent.

Free charging-stations can be a security risk. When you plug your phone into these stations, you are, essentially, giving a stranger access to your device. Hackers have been known to set up fake charging-stations in public places, which can steal your data, or even install malware onto your device.

Another danger to consider: free charging-stations can be harmful to the health of your device. When you use one of these stations, you have no way of knowing whether it has been properly maintained, or if it has been damaged in any way. This can lead to power-surges or overheating, which can cause irreversible damage to your phone.

To protect yourself and your device, it is important to take precautions when using free charging-stations. Here are some tips to keep in mind:

  • Use your own charger, whenever possible. It is always better to be safe than sorry, and using your own charger ensures that your device remains secure and healthy.
  • If you must use a free charging-station, use a portable charger, instead. Portable chargers are small and easy to carry around, and they allow you to charge your phone without the need for a public charging-station.
  • If you must use a free charging-station, use a USB data-blocker. This is a wonderful device that blocks data-transfer through a USB port. This prevents hackers from accessing your data while your phone is charging.

While free charging-stations may seem like a convenient solution to a dead phone-battery, they actually pose a significant risk to the security and health of your device. By taking the necessary precautions and using your own charger, whenever possible, you can ensure that your phone remains safe and healthy. So, next time you are out-and-about, and your phone-battery is running low, remember to think twice before plugging into a free charging-station.
