This Super Charger Is The Size of a Credit Card

Most mobile chargers are big ugly bricks that need their own carrying case. But the LithiumCard is small enough for a pocket, and more powerful than any charger you've got.

The LithiumCard is the size of five credit cards stacked on top of each other, which means it will fit in most wallets or back pockets. It packs a powerful punch of energy, claiming to deliver one percent of battery power per minute to your smartphone. That means a dead iPhone will reach a 15 percent charge in just 15 minutes. It has built-in wires to minimize tangling, and a flip-out USB connecter. Available with either an Apple Lightning connector or micro-USB, the LithiumCard can power your Apple device or your Bluetooth speakers, headphones, and other gadgets.

It comes in three colors, and also features Nanostick, a sticker that allows you to pop your LithiumCard to the back of your smartphone with hardly any added bulk. Plus, it's starting at just $40.
