'Better Re' is an ingenious new device that takes the leftover energy from old lithium batteries and uses the remaining power to charge new devices. The clever up-cycling battery packs help to ensure that all the leftover juice in your old smartphone is no longer going to waste.
Better Re was designed by a South Korean startup that sought to provide an eco-friendly solution for consumers to recycle the batteries in their old devices. To use Better Re, simply remove the lithium battery from an old smartphone and place it inside the power pack. The device can then be used to charge anything with a USB cable.
Since most discarded smartphone batteries still contain up to 80 percent of their original power, Better Re helps ensure that all of that leftover energy can be used for a new purpose.
