    Portable power pack

    I got this power pack because my phone is older and won't stay charged. This works very well. It came ready to use and holds charge for a long time. I like that it shows how much charge is available on it when you plug your device into it. It is heavy but I don't carry it all the time so that's not a deal breaker. It charges my phone and has never gotten hot like some do. It stayed cool to the touch. This makes me feel like it is safe.

    Everything it is advertised to be!

    The unit was already partially charged upon receipt. While charging it to full capacity, it would only reach 86%. Online research instructed to discharge the unit to 50% and upon doing so, it now reaches 100% charge! The unit has multiple outlets to charge more than 1 device simultaneously. I will be using this mostly for my phone and needed a power bank for times when there are extended power outages from hurricanes/storms here in Texas. The unit is heavy and not petite, BUT, when one needs power, this is great insurance to keep your device operational. If you are looking for a compact, lightweight power bank, this probably isn't for you. So far, I am pleased with my purchase.

    Energizer power bank

    Havent had it very long. Bought it to take with me on a trip. I was gone 8 days and it kept my phone watch and tablet fully charged the entire time. I was at the beach a few days so i wasnt using them all the time. But i am still impressed. For the price i feel it should be that good, and it didnt disappoint! With Heavy useage id guess about 4-5 days before it would be out of charge. I like the mutiple input/output ports it has, however it did take all night to recharge. Included in the photos are the charge\discharge information on the back of the decive for those interested.

    Great Value, Great Capacity

    The Energizer battery pack is very simple to use. You can charge it with a micro USB, USB-C, or Apple charger. It outputs to up to two USB cords so you can charge two devices at once. The digital display on the battery pack clearly shows how much charge the battery pack has. It comes with a short USB to USB-C charging cord that was perfect for me since I have a Samsung Galaxy. The charger is about the same size as my Galaxy 9, and about twice as thick. Even though it's large, it is very effective. I would buy it again.

    Made for long trips.

    This is a great battery. It last long but it should because it’s as large as a mini-tablet. I was able to charge multiple devices without a hitch. Note it takes a long time to charge so do it well before a trip.
