# Qi Wireless Recharging Battery Case ## Introduction Usefullness of a mobile device diminishes greatly when its batteries cross the [River Styx](https://en.wikipedia.org/wiki/Styx); passing from the land of the living into the realm of lost socks. ![](https://cdn-learn.adafruit.com/assets/assets/000/025/925/medium800/components_IMG_6059.jpg?1434234994) **Add a battery case? ** Sounds like a great idea, but you might have to give-up wireless charging (if your phone has it).

I would recommend using the Qi charging stickers that terminate in Micro / Mini USB connectors. For this guide, we will use the Qi Universal Charging Module and integrate it into a Nexus 5 Limefuel battery case.
