Customers are saying

Customers admire the 10,000mAh 22.5W Magnetic Wireless PowerBank for its fast charging speed, overall performance, and portability, with the digital display being a valued bonus. The battery life and design also receive positive feedback, along with its convenient Apple Watch charging capability. However, some customers have noted that the power bank tends to get hot, and a few find the weight and magnet strength to be less than ideal.

      Hi SrikanthS,
      We’re sorry to hear about the heating and slow charging issues. Wireless magnetic charging can generate some heat and is generally slower than wired charging due to efficiency limits. The 10,000mAh capacity typically provides about one full charge for high-consumption devices like the iPhone 15 Pro Max. For faster and cooler charging, we recommend using the built-in USB-C cables. If the heating seems excessive, please stop using the power bank and contact our support team for assistance:

    Works good for the price point and is convenient/ durable, plus the battery tracker is neat. But is bulky, heavy, and is slow to charge generally compared to cables.

      Hi MikeA,
      Thanks for sharing your thoughts! We’re glad you find the power bank convenient and durable, and that the battery tracker is useful. Bulk and weight are common trade-offs for higher capacity, and wireless charging will generally be slower than wired due to energy transfer limits. For faster charging, we recommend using the built-in USB-C cables whenever possible.

      Hi Thatone,
      Sorry the power bank didn’t last long with your iPad. Larger devices like tablets draw significantly more power, so a 10,000mAh unit can drain quickly. This model is better suited for phones or smaller accessories.

      Hi Adam,
      Thanks for pointing that out! This model is designed as a wired power bank with built-in USB-C cables for convenience, and while it has a magnetic design for easy attachment, it does not support wireless charging. We appreciate your feedback and will make sure product descriptions remain clear for future shoppers.

      Hi Isaac,

    Very slow when you use the wireless charger. The built in chargers work a bit better, but it overheats fast. Definitely not worth the price.

      Hi Lexi,
      Wireless charging is naturally slower than using the built‑in cables, so what you’re seeing is normal. We also recommend not waiting until your phone drops below 70% before charging—very low battery levels draw more power and increase heat. If the device continues to feel unusually hot, our support team can help check or replace your unit:

    Unboxed and I really like the design of packaging. I turned it on and it had 78% power. I put my phone over the top and it initially started to work, but after a few seconds it stopped. Couldn't get it to work again. Brought it back to Best Buy, and the return person had the same experience I did. So it was returned with confirmation from somebody else.

    I reslly thought this was a steal compared to the Mag Go by anker, but its just a cheaper plastic build that had potential, until the screen didnt display anything. I was hoping it woukd once I connected to the wall or charged my phone. Nothing. I now must return it, its ine of the best features of thr device. Sure the built in cables and stand are cool, but without thr working display, it is a buzz kill.

      Hi ScarletDevil, we're sorry for the confusion. The magnetic wireless charging on the UE10035C is designed for MagSafe-compatible devices. For the Galaxy S25 Ultra, wireless charging may be limited, but the USB-C cable charging works great at full speed. Need help? Visit https://support.energizerpowerpacks.com/.

      Hi Raja,
      We’re sorry the power bank feels heavy and charges slowly. Larger capacity models like this one tend to weigh more, and wireless charging is generally slower than wired charging. If the unit occasionally turns off, please check alignment and ensure the device is centered. If the issue persists, contact Energizer support for assistance or a possible replacement:

      Hi Herman,

      Hi DwayneJ,
      Sorry for the trouble. Please ensure the power bank is fully charged and your phone is properly aligned with the magnetic charging area. Thick phone cases can block wireless charging, so try removing the case. If it still doesn’t work, contact us at https://support.energizerpowerpacks.com/ for assistance.

    It charges quickly and holds the charge for 3-4 days if lightly used (Apple watch). Charging a phone depleted it sooner. Convenient as power bank backup especially with built in cables.
