    Its a little bulkier than the Mophie Juice pack, yet for the price it worked great and the magnet stuck to the phone like crazy.

    The magnet is really good. It doesn’t pull off my phone. It will charge my phone about 75%. I have an iPhone 16. I wish it had a bigger battery life.

      Dear TaylerV,

      Thank you for your review!
      We also appreciate your feedback on the charging capacity. While our 5,000mAh power bank is a great portable solution, it's normal for it to provide about a 75% charge. This is because of energy conversion loss, a natural part of all wireless charging. Some energy is lost as heat during the transfer from the power bank to your phone, so the total capacity won't translate to an exact percentage increase. For a full charge or more, you would want a higher-capacity power bank.

    Full charge struggles to do a full phone charge. But it’ll keep your phone from dying.

      Hi Amoxtlin,
      Thanks for your honest feedback. The 5,000mAh capacity is designed for emergency top-ups rather than full phone charges—especially for larger devices like the iPhone 15 Pro Max. It’s great for keeping your phone alive when you’re on the go, but it may not fully recharge it from 0%.
      If the performance seems unusually low, we’d be happy to check it for you. Please visit https://support.energizerpowerpacks.com/ so we can assist further.
