NPoole, a user on SparkFun designed a battery-charging smartphone case based off of Pokédex. All you’d need to make it yourself is access to a 3D printer, a lithium ion battery, a USB breakout, a power cell, and the designs (Which are available for free HERE on GitHub). So thanks to NPoole, we can live out our dreams of being “real” Pokémon masters (through our smartphones of course)!
