Griffin Reserve Convertible Battery Case for Samsung Galaxy S3

Unlike traditional battery cases, which keep the bulky battery tied to the phone even when its depleted, Griffin Technology’s reserve-convertible case lets users connect the battery as needed. While the battery is detached, the case complements and protects the Galaxy S III’s design with its slim, hard-shell design. Snapping the battery into place connects it directly to the Galaxy’s charging port, allowing 2,000 mAh of juice to quickly replenish its charge.

  • Model number: GC36568
  • Hard-shell case
  • Detachable 2,000 mAh battery pack
  • Micro-B USB connector
  • 5-volt DC; 1-amp charging power
  • LED charge-status indicator
  • One-year warranty from Griffin Technology

The product doesn't increase my battery that much. After unplugging my phone my total time ranges 8-9 hours until my phone dies. Not really worth it.

I love the fact that you can disconnect the external battery when you don't need it.
