Roger® for Samsung Galaxy Alpha 2600mAh Battery Case External Battery Charger Case Backup Power Bank Rechargeable Power Case with Kickstand (Black)

Nice product to have since the samsung galaxy alpha's batter drains quickly, but it doesn't really give a full charge. If you cut your backup case on at about 50, you will get to 100 percent on a full case charge. And also when you charge both at night starting with the phone and the case automatically charging afterwards, the phone will lose a little juice maybe 5 to 10 percent over night while being idle.

I love mine it is the bast care I have got so far
