Editor comments:
In power bank industry, more and more people like things simple, convenient and easy to go. This credit card power bank is popular by people because of its slim shape and lightness with universal capacity which can charge iphone once at least.
It is really convenient to take since you can put it in your pocket or wallet.
Its best characristic to make me satisfied is the somehow metallic feeling.
