    Bought two a couple of weeks ago, took one out to test it had 50% battery on iphone took about 45 mins to get at least 70% charge iPhone recognized it as a slow charger. For some reason the maganet failed and when I picked up the phone the charger fell to the ground and broken open exposing all components inside. Called energizer customer service and just refered me to the store to return the product. Would of figured it would of held up to drops like other products,but it did not.

      Hi Garcia22,
      I’m sorry this happened, and I understand how frustrating it is when a new charger doesn’t perform well. iPhones are limited to slower Qi wireless charging speeds by design, so they may show “slow charging” even when using a higher‑wattage wireless power bank. Your concerns about the magnet and durability are completely valid, and we’ll make sure this feedback is shared with our internal team for review.

      Hi ChristinaV,
      Sorry to hear the power bank gets very hot with your Ultra 24. Slim magnetic models can warm up more during use, especially with high‑power phones, but it still shouldn’t feel excessive. If the heat is unusually strong or affecting performance, please reach out through our support page so we can assist you:

    I have an iPhone 15 Pro and it supposed to be compatible, which it does charge. However, it attaches to the phone upside down which covers the camera and becomes bulky of the odd way it sticks out. Won’t purchase again.

      Hi MoMoney,
      We’re sorry for the inconvenience with the magnetic alignment on your iPhone 15 Pro. The slim design can sometimes cause the power bank to attach in a way that interferes with the camera, especially on larger models. We appreciate your feedback and will consider this for future design improvements to ensure better compatibility and user experience.
