    The magnetic wireless feature didn't charge either of our iPhones (13 and 15 models) and only worked with wired connection. Cases were removed and still no charge.

      Hi IsidroO,
      We’re sorry to hear the power bank didn’t meet your expectations. The Ultimate Lithium 5,000mAh is designed for lightweight portability and quick top-ups, but if it’s draining faster than expected or not delivering sufficient charge, there may be a performance issue.
      Please visit our support page at https://support.energizerpowerpacks.com/ so we can help troubleshoot or arrange a replacement if needed.

      Hi Revjcollins,
      Sorry to hear the wireless charging didn’t work with your iPhone 15. This model is designed to support MagSafe-compatible devices, so if it’s not charging, there may be a fault with the unit or a compatibility issue we’d like to investigate.
      Please reach out to us at https://support.energizerpowerpacks.com/ so we can help troubleshoot or arrange a replacement if needed.

      Dear JakeJ,

      We are truly sorry to hear about the issues with your new power bank. It's incredibly frustrating when a new product doesn't work as it should, especially when the ports are broken. The slow charging could be related to the cable or the device you are charging, but the broken ports are a clear defect. We want to make this right for you. Please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so we can assist you with a warranty claim.

      Hi IbrahimM,
      Thanks for sharing your thoughts! We're glad the power bank worked well for short trips. While its compact size and magnetic wireless charging make it convenient, it’s true that for extended travel or charging larger devices, a higher-capacity model might be more suitable.
      If you ever need help choosing a model that better fits your travel needs, we’re here to help!

    Did not wirelessly charge iphone 14

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Just a average 5K charger and not worth the price when you can buy a 10K charger for less, even the same brand. Did not wirelessly charge my iPhone 14 with or without the case.
