2000MAH Power Bank External Rechargeable Battery Case Emergency Charger Case Cases For Samsung Galaxy S3 i8190 Mini BC161B (Wireless Phone Accessory) 4
This shell is a good quality / price ratio because when I see an ordinary hull 30 euros in supermarket .. The shell is rigid and protects the phone well. It is easy to use no need to read the manual! It charges the phone completely but only when it's off! And with that my battery shell is stronger I think.
