Never thought I would see the day when I would need one of these but it came. A Power Bank Charger. In fact, I now have two.
We are all so dependent on our mobile phones for things like texting, checking social media, directions, selfies and even pokemon, it is no surprise that all this eats into the battery life.
Solution is to buy a spare battery. Cheaper solution would be to get a power bank which is most of the time, at least 50% cheaper than the original hand phone battery.
