Invest in a portable phone charger

Hackers can use public charging stations to install malware on your device, so we recommend never using a public phone charger. However, if you are out and your phone is about to die, you may feel as though you don’t have any other choice. If you invest in a portable phone charger and keep it in your purse, briefcase or backpack fully charged at all times, you will have a back-up battery in case of an emergency, and you will never need to use unsecure charging stations.
