For some reason, people are obsessed with making devices the shape and size of a credit card…

Update: Another company by the name of “Powerocks” based out of ShenZhen, China released a similar product called “Tarot,” which they refer to as the “world’s thinnest portable power bank.”

The Tarot is able to provide an emergency charge to smartphones, tablets, cameras, and other mobile devices quickly while on the go.

To charge a device, you need to connect the included Micro USB cable or use a USB adapter for iPhones and other devices that don’t use Micro USB.

It has the same dimensions of a credit card, but is considerably thicker, with a height of 0.28 inches. Still, they claim it is designed to fit it in your wallet.

But wait, there’s more. Another company by the name of “WiFlux” says it has created the “world’s first wireless portable power in a card.” It actually appears to be the same shape and size of a credit card, and possibly just as thin.

This one works a little differently – basically all you have to do is place the razor-thin device on the back of your phone, in between the phone and the case. It will then charge the battery automatically. Of course, it’s still in development, with a funding goal of $100,000 needed to see it through.
