    I got it as a gift. It has charged my phone about 3-4 times fully on a fill charge. Totally recommend.

    Swollen Battery

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    It worked great for about 2 years. Last year in the summer I noticed that the battery got really hot and swelled up. I haven’t used it since then. Seems like a scary hazard to have around. I have multiple battery chargers and it’s the first time I’ve had this issue. I started reading the reviews on here and it seems at least one other person has had this problem. I treated the battery the same way the others, charged until fully charged and use it for my hiking trips. I had this one plugged for a little under 30 minutes when I saw it was swollen. Will add pictures of it once I get some

    Excellent battery backup. Needs a good power adapter to charge it though. Magnetic interface for wireless charging would have been good.

    So far the battery charger works great. I wish it would charge my phone a bit faster, but for the price it is fine.

    I didn't like this battery, it doesn't charge well, the cell phone slips or moves a little and doesn't charge, and it takes too long to charge my cell phone.

    Not impressed

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    First battery I got was bulged so I had to exchange it. Best Buy was out of stock so they had to order it. That was on January 7th. It was supposed to arrive by the 11th. Today is January 19th and it hasn't even shipped yet when I check tracking. UPS says the label has been created but they have not received the item. Best buy has not updated me at all. So this rating is a combo of Best buy and the Energizer battery.

    "20W qi" charger only supports 10W qi

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    "20W qi" wireless charger but is actually a 10W qi charger. I guess we need to carefully read the fine print. Also, not magnetic/magsafe.

    Is my charger defective??

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This charger has not impressed me - it does not seem to hold a charge and I can rarely get more than one phone charge out of it. Is there a way to check to see if it is defective or not?

    Bad Buy

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This power pack stopped working after only a month. It would never fully charge, and then only would charge phone for 5 minutes before powering off. Unfortunately Best Buy only has a 2 week return policy.
