    Decent wireless charger. However, this battery gets really hot and almost makes the phone unusable.

      Hi Sotheas,
      I’m sorry the power bank is heating up so much during wireless charging. Some warmth is normal with magnetic wireless charging, but becoming hot enough to affect phone usability isn’t expected. Our support team can help check whether your unit may need replacement or further inspection:

    I bought this for a trip coming up to Peru, where I’ll be gone for two weeks, and each day “out of the house” dawn to dusk. Wanted something to juice up my iPhone 16 Pro Max, and while it does a good job being an “extra battery”, it doesn’t exactly kill it in the power department. I think for smaller phones it might be okay, or with managing your expectations that you use it as an extra start to your battery life early in the day, where you use your phone with it attached, and then once it runs out it runs out. But expecting to charge it up back to full is gonna be tricky, so keep that in mind with your expectations.

      Hi JoshJ, thank you for sharing your experience. The 5,000mAh capacity is designed for portability and quick top-ups rather than full recharges for high-capacity devices like the iPhone 16 Pro Max. For extended trips or heavy usage, we recommend starting the day with the power bank attached, as you mentioned, or considering a higher-capacity model (10,000mAh or more) for full-day coverage. If you have any questions or need assistance selecting the right option, please visit https://support.energizerpowerpacks.com/.

      Hi Akparker,
      We’re sorry to hear the power bank gets very hot during use. While slight warmth is normal, excessive heat is not and may indicate a defect. Please stop using it and contact our support team for assistance or a possible replacement:
