Popkord, a neat little accessory designed by Powergoat, is a good-looking keyring equipped with both Lightning and microUSB connectors.
The device is very simple as it consists of an USB port, a connector, and a cord hidden in a sleek strap that you can attach to you keys. When your phone is running low on battery, all you need to do is to extend the cable and plug it to a computer or into a wall socket.
Popkord sports a stylish look and is made of high-quality materials. It can be bought in one of four colour combinations for $30.
