    Excellent product. Lightweight and portable. Charging fast. The casing feels cheap, not solid. I would give it a 5 stars if it feels solid.

    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/.

    I do not use this product often. However when I do, it gets really hot fast. I do not feel comfortable using this whenever I need a back up charger

      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:

      Hi ArrieBoom,
      Thanks for your feedback! Wireless charging generally delivers slower speeds compared to wired connections due to technology limitations, even though this model supports up to 15W. We appreciate your input and will keep it in mind for future improvements.

    The magnet holds strong and it charges relatively quick especially on older iPhone models, namely iPhone 13. Product comes with its own USBC charging cable and it does charge up somewhat slow but its a tradeoff.

    Purchased two of these when on sale. Arrived quickly and they are great to have and carry around. Just attach to MagSafe phone cover and it provides power to the phone. Very Satisfied. Not large and bulky like some PowerBanks.
