    I needed a charger for my iPhone for when I am out and about and my phone powers down. This is just what the doctor ordered. Thanks so much for the wonderful recommendations.

    Exactly what you'll expect from an energizer product. Lasting battery pack but takes a long time to charge the power pack itself

    Bought this item back in January 2022, worked great, kept the GoPro and android charged. Now in September, the LED lights on the side do not work. I cant tell if the pack is taking a charge or not. Would've given 5 stars if the unit still worked right.

    I agree with other reviewers stating that it's frustrating to try to tell if the charger is even fully charged. Despite plugging this in, waiting different amounts of time for the charger itself to recharge, trying different charge cords, etc this product didn't work at all. Yikes.

    It sure is nice to be able to carry a reliable power source with me. The energizer back-up battery lives up to its reputation. Haven't had any problems with it.
