    The backup battery seemed like a good deal at $15 for 10,000 mah and magsafe wireless charging. Even with it being Energizer brand, the quality of it was pretty cheap looking and feeling. The charging seemed to work just fine at first, used it maybe twice with one of the times being wireless with a magsafe case. It was really slow but seemed to work at least. Next time I went to charge wireless, the battery wasn't charging my phone. The casing of the battery backup pulled apart, as you can see in the pictures, when I took it off of my phone case. It felt hot and had a bit of a smokey smell but no visible smoke or anything like that. I wasn't about to go plugging my phone into the USB-C port to see if that still worked. Returned it and got a refund from Best Buy minus a $5 Reward that I redeemed. I have a Samsung Galaxy S24 Ultra and a UAG case with magsafe built into the case so not a cheap case with magnets put on it or anything like that. Would not recommend this product and wonder if the Energizer backup batteries without wireless charging are better or not.

      Hi Patrick,
      We’re very sorry to hear about the overheating and casing issue you experienced. That’s definitely concerning and not the quality we aim to deliver. It’s good that you returned the item for safety reasons. Regarding your question, non-wireless Energizer power banks generally have fewer heat-related risks because they don’t include magnetic charging components, but performance can still vary by model. If you decide to try another, we recommend checking reviews for wired-only models to ensure reliability.

    This has been a necessity with my busy life and man is it nice not having to deal with a cord. On another note the charging screen changes when you attach it to an iPhone and it tells you not only the phone battery but then below it the battery of the battery pack. I love this thing

    Battery life could be better. Not exactly as advertised but does what it’s supposed to - charge. The MagSafe doesn’t have a strong hold or line up properly.

      Hi Zach,
      We appreciate your feedback. Battery life can vary based on device type and usage, but we understand your concern. For the magnetic alignment and hold, ensure the phone case is MagSafe-compatible and free of metal or thick layers, as these can weaken the magnetic grip. If the issue persists or feels like a defect, please visit https://support.energizerpowerpacks.com/ for assistance with troubleshooting or replacement.

    This power bank is a massive safety hazard. It was my first time ever using it. I plugged it in to charge it up, placed it in my bag, and when I went to plug my phone in later, it wouldn't work. When I looked closer, I discovered visible burn marks and melting around the USB port. ​It clearly suffered a severe internal short circuit right out of the box. Having a defective battery like this heat up inside a bag is incredibly dangerous and a massive fire risk. I am lucky it didn't ruin my phone or start a fire. Absolutely do not buy this product—it is completely unsafe.

    I bought this Energizer power bank less than a month ago, and I'm already writing this review as a warning. In just a few weeks, the battery has swollen to the point where the case is noticeably deformed. I’ve treated it well, keeping it in my work bag and away from any sunlight or extreme temperatures. It's really concerning because a swollen battery can be a fire hazard. Now I'm stuck with a product I'm too scared to use or even keep in my house. While it was a great charger for a short time, the risk is not worth it.

    Review for the magnetic portable

    Worked well for about two weeks and then stopped charging properly and had to constantly move it around the back of my phone to charge. Quality of the side that slaps onto the back of your phone is thin, fragile, and will bend inwards if pressure is applied.

      Hi DiscoDancingUnicorn,
      Sorry the casing bent and caused issues with the USB‑C port. This model is designed to be lightweight and slim, so the shell isn’t as rigid as heavy‑duty power banks. Your feedback is important, and we’ll share it with our design team.
