    Worth to buy

    posted by tarumar on 10/22/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Good material quality. Easy to fit the phone in it. I don't think it's really 2800 mAh but it's a least 2000, which is good and nearly doubles the battery capacity, when you are outside. It also protects the phone very well. I dropped it a few times (altho...
    Cons:
    It's big, heavy and makes the phone look ugly. That's why I usually keep it in my handbag and use when necessary.

    Cons:
    The blue lights at the front of the device are really bright and it bugs me a bit as they remain ON all the time it is charring...

    Rechargeable External Battery

    posted by isadoracarneiro on 04/07/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Charges the battery just like the original charger, not heavy at all, once you get it, it might seem that it's huge, but once you attach your phone into it, you realize that it's not so big at all
    Cons:
    It takes about 4 hours to charge up to 80%, it doesn't charge more than that. It doesn't have any more cons.
