Startlingly slim, yet seriously sturdy, the PowerCase for Samsung Galaxy SIII boosts your battery life beyond its basic boundaries. It’s the world’s first power-boosting case for Samsung’s sweet new smartphone.

Designed and engineered to ensure the super-sleek sexiness of the SIII isn’t squandered, the PowerCase even provides extra protection for ports and plugs, and only adds 80-odd grams to your pocket.

Simply slip it into the PowerCase and charge your phone as normal; the powerful lithium-polymer backup battery will soak up all the juice it needs to provide power in a pinch.

Customer Reviews

The PowerCase for the S3 was the best firebox buy I've made this year. It is easy to use, just pop the phone in the case and press the on button (don't forget to charge the case first)and forget. A great buy! To all the S3 owners out there I say...go on you know you want it and to all at Firebox you guys are awesome! Thank you very much.
