ChargeCard Ultra-Thin Power Bank With the Size of a Credit Card

Due to the size of a conventional battery, a typical power bank is usually bigger than two phones stacked together. This poses a problem for people who relies heavily on such device to extend a phone battery on the go.

Enter ChargeCard, an ultra-slim power bank that is literally head-to-head to a standard credit card. Of course, it’s slightly thicker to accommodate electrical components, but it is certainly can be stored in a wallet or the back of a phone case.

The 2300mAh power is probably won’t fully charge a modern smartphone, but is useful for emergencies and definitely won’t be irritating to carry.
