    Doesn't blow me away with how much it holds or how fast it charges, but it suffices for my purposes and was the most affordable option.

      Hi TaraS,
      I’m sorry your power bank only charges your phone intermittently and that you have to wiggle the cable to make it work. That usually points to a loose connection in the cable or the port, which isn’t normal behavior. Please contact our support team so we can help check the unit and assist with a possible replacement:

    Disappointing Performance Despite Nice Design

    I had high hopes for this Energizer power bank, especially with the LCD screen and compact design. Unfortunately, the performance was underwhelming. It barely charges my iPhone 15 to 50% before running out of battery. For a 5,000mAh device, I expected much better output. While it feels solid and is easy to carry around, it just doesn't deliver enough power to be truly useful. I wouldn’t recommend it if you're looking for something reliable to get you through a full day.

    No, I would not recommend this to a friend

      We are sorry to hear about your disappointing experience with the power bank's performance. While a 5,000mAh power bank's capacity is large, the actual charge it can provide can be affected by factors like power conversion loss and your phone's power consumption, especially if it's in use. If you are experiencing any other issues, we would be happy to help. Please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so our team can assist you.

    NO CLEAR AND UNDERSTANDABLE INSTRUCTIONS WERE PROVIDED. I went four times to BEST BUY customer service - one hour drive, and No Clear Instructions were provided to me. Very bad customer service.

    Easy to use and charge. Doesn’t have as much charge as we expected. Only lasted about 45 minutes minutes charging a heated vest.

      Hi JosephL,
      Sorry the runtime didn’t meet your expectations. A heated vest draws significantly more power than a phone, so a 5,000mAh power bank can drain much faster—often within the kind of timeframe you experienced.

    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.
