The development of smart phones is rapid, but the battery life problem has always been criticized. Battery technology is far behind the pace of mobile phone functions. Power banks have become a must-have for heavy mobile phone users. Bring something. But no matter which pocket you put the power bank in, it feels inconvenient. It would be much more convenient if it was thin enough to fit in your wallet.
Plusus Design Studio has designed a power bank called Lifecard. As the name suggests, it is thin enough, only 4mm thin, and can be put into a wallet like an ordinary card. Lifecard has a high-end appearance and is designed with a full metal surround. The battery capacity is about 1500 mAh, which is roughly equivalent to the power of an iPhone 5S. Although the capacity is not large, it is still suitable for daily emergency use. The key point is that it is thin enough and easy to carry.
