Low battery power becomes a constant nightmare when one is travelling without time for adequate charging. Many of us have the tendency to use USB ports installed on public places for a quick recharge.
The problem with this ‘solution’ is that charging phones through public USB ports have the potential for quick compromise by hackers.
The technique used by hackers is referred to as “juice jacking” through which your personal data and much more can be easily identified and stolen.
If you decide to use such a public USB port, make sure you have disabled access to your device data.
The better option is to plug your phone’s charger to an AC outlet. They use a fairly small amount of space (no mobility issues).
