Smartphones have become an indispensable tool for most of us. We use them for a wide range of activities, from gaming to checking social media to accessing work apps. Because of heavy use, our smartphones may sometimes run out of battery. When that happens and you’re out in public with no access to your charger, using public charging kiosks to bring your phone back to life can seem like a good idea — but it’s not.

Smartphones have become such a vital component of the modern lifestyle to the point that we are always glued to them. And as our time with our gadgets increases, the need to recharge them while we’re on the go also increases. When you’re nowhere near your charger and your juice runs out, that public charging kiosk can look pretty promising.
