Power banks are very popular in Asia and Europe but why aren't they as popular in the US if we are more smart phone friendly. The answer is transportation; not a lot of cities in United States are transportation friendly so this allow a vast amount of population to spend a 25 % amount of time daily in their vehicles which means and alternate power source to charge our phones.
I feel that we all need a Power Bank and i know the popularity of power banks is increasing dramatically. We never know when we might need charge for our phones never the less in an emergency situation having low battery can be horrible. I invite all of you to invest in a Power Bank, i can guarantee you'll thank me later.
