Many of us upgrade our phones every couple of years. The old phone that you replace still has a battery that can be upcycled. The BETTER RE happens to be a power pack that lets you use old smartphone batteries to recharge your gadgets. It works with any smartphone battery and supports expansion packs for more capacity.
The BETTER RE kit is pretty easy to use. Just insert your battery and close the case to get started. Did we mention that the kit has a stackable design? You can find out more on Kickstarter.
