Features & Highlights

Why you should buy this product

If you've ever owned or wished you owned a Swiss Army knife, you know that more utility is always better. This Smart Battery can be used as a universal charger OR as an extended battery for a phone with a Third Rail case on it! First, the 1250 mAh rechargeable lithium polymer battery has a micro USB port, which allows charging when a data/charging cable is plugged in to a phone. The battery pack can also be attached to any Third Rail case and with the conducting metal tabs, act as an extra power source for your phone! Additionally, these Smart Batteries can be stacked which creates a more powerful energy hub! This stackable hub can charge multiple devices at the same time, so if you and your friends get the Smart Battery, you can charge your phones all at the same time, leaving the wall outlets open!
