    Gets hot and makes me nervous

    The charger works okay with my iPhone 14 max pro, and it’s a good price point. It’s slower than my regular charger, but it’s not terrible. The magnet is strong—no problem there. The only thing that I really don’t like about it is that it gets quite hot when in use. To be on the safe side, I try not to use it on or near something that is combustible. And I wouldn’t leave it in a hot car, even if it wasn’t in use. The fact that it makes me nervous is a bit distressing, and I’m wondering if I should have gone with something a little more expensive but seemingly safer.

      Hi Michelle,
      Thanks for your honest review. We're glad the charger works well with your iPhone and that the magnet holds strong—but we’re truly sorry the heat issue is making you feel uneasy. Portable chargers can warm up during use, especially when fast charging or wirelessly charging, but they should never get uncomfortably hot.
      Also, if you're using a thick phone case, it may cause poor contact with the wireless pad, leading to slower charging and more heat buildup. For safety and performance, we recommend using a thin, MagSafe-compatible case and avoiding use in high-temperature environments like a hot car.
      We take this issue very seriously and apologize for the problem you've experienced. 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 provide you with support.

    I was hesitant to get this portable charger because of the mixed reviews online. I am glad i ignore the reviews and follow my gut feeling. This is a very good charger, it charges my phone real fast. I have no complaints. I was able to charge my phone and my earbuds at the same time. This is definitely a good buy.

    I purchased it Because of the light weight and fast charging... unfortunately, I'm not completely satisfied with this item. It tends to heat up while I'm charging my cell.

      We're sorry to hear that you're not completely satisfied with your power bank due to the heat it generates. While some warmth is normal during charging, excessive heat is not. This can sometimes be caused by a misaligned phone during wireless charging. For the best performance and to minimize heat, please ensure your phone is centered on the charging pad. If the heating persists even with proper alignment, please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so we can assist you.

    I haven't needed to use it during an emergency, but I did have it recharge my phone successfully. It is a little bigger & heavier than I'd hoped, but still quite portable.
