    Great portable charger for the price. Wont find something better and more cost efficient in Alaska. Itll fully charge an iphone 16 pro max about 3-3.5 times until it dies. It does take forever to fully charge, but its not a big problem

    I used it for my trip back home, but after 2 months of using it it stopped working. Charged it to 86 and when I unplugged it, it says 0. So, love how fast phone charged but broke after a few months is using.

      Dear Rice,

      We're very sorry to hear that your power bank stopped working after just two months. The issue you described, where it shows a high charge and then immediately drops to zero, is a clear defect and is not the quality you should expect from our products.

      We’re glad to know you were happy with the fast charging performance while it was working. We'd like to help you get a product that's both fast and reliable.

      Please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so our team can assist you directly with a replacement.
