    Pretty big and bulky. Works fine, but heavy to carry around. Sometimes when magnetically charging it goes off pretty quick. Wish I had bought the smaller version so I could carry it around easier.

      Dear DarioFC,

      Thank you for your feedback. We are glad to hear the wired charging works well for you. We apologize, however, for the issues you are experiencing with wireless charging and the unit's weight. Wireless charging is naturally slower than wired charging. The issue of the unit stopping at 60% is not the performance you should expect. We want to help resolve this for you. Please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so our team can assist you with these issues.

    I was about to return this power bank because it gets warm every time I charge my iPhone, and it’s a bit too heavy to carry in my purse — not the most convenient for travel. However, it does charge my phone well and performs reliably once connected.

    No, I would not recommend this to a friend

      Hi AnalynH,
      Thanks for your honest feedback. We’re sorry the weight and heat during charging made it less convenient for you. While the power bank is designed for high-capacity performance, we understand portability and comfort matter too — especially for travel.
      If the warming feels excessive or you're concerned about safety, we recommend reaching out via https://support.energizerpowerpacks.com/ so we can take a closer look.
