    My husband purchased this portable charger to use when traveling. He has only used it once to confirm it would work with his phone. He seems to be satisfied with it although it doesn’t charge the phone to full charge. I’m assuming that this is normal.

    Battery performs poorly - very disappointing!

    The battery did not have much power to it. It took 4 hours to charge my phone only 30%! I gave it a second chance, but the battery's performance did not improve. It was even slower. My initial impression of the battery was good, as it is very lightweight and wouldn't weigh down my purse or fanny pack. But due to its poor performance, I decided to return it and get a refund. I have a battery that I purchased 7-8 years ago now, and it can fully charge 2 phones much more quickly than this! This purchase was disappointing, as I expected this battery to be high performance (as it is made by Energizer, a trusted name brand).

      Based on your description, it is possible that the issue you are experiencing could be related to compatibility.
