Features:
1,Slim Extended Battery Case,which looks more compact, shorten the thickness and lighten the unnecessary weight.
2,Featuring sync-through technology that you can sync your iPhone to a computer through lightning cable without having to take the battery case off.
No more need to carry another cable around as you travel. Use one lightning cable and you don't have to remove the phone from the case to charge them both individually.
If you plug in the cable, your phone will charge first, and when it's topped off, then the case will charge.
3,Has a nice design that allows you to easily put the phone in the case and remove.
