    it works very well. Its battery lasts a long time and lasts a long time. It's a bit heavy. You can see its battery percentage because it has a large screen for easy viewing.

    Portable Battery Charger

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

    I bought this charger for use when I’m not home or traveling. I missed having one at a conference last month and hated to have to find electrical wall plug to plug my device to charge it. As I checked this energizer portable battery charger to see how well it would work, it seemed to do everything it was purposed to do, even the LCD screen. I like that it has different USB inputs and outputs and can charge up to 3 devices at a time.

    Review, Energizer portable battery for cell phones

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

    I bought this electronic battery to support two cell phones on an international trip. The battery performed exceptionally. Several times I have recharged my cell phones. An additional feature is that the battery displays the level of its charge which helps determining how much charge its losing while connected to the cell phones. IT also has two USB connectors so it can charge two cell phones at the same time.

    I would recommend this to a friend
