    Doesn’t attach easily without covering the camera

    I have an iPhone 15 Pro and it supposed to be compatible, which it does charge. However, it attaches to the phone upside down which covers the camera and becomes bulky of the odd way it sticks out. Won’t purchase again.

      Hi MoMoney,
      We’re sorry for the inconvenience with the magnetic alignment on your iPhone 15 Pro. The slim design can sometimes cause the power bank to attach in a way that interferes with the camera, especially on larger models. We appreciate your feedback and will consider this for future design improvements to ensure better compatibility and user experience.

      Hi George,
      Sorry the magnetic attachment didn’t stay secure for you. This model uses a gentler magnetic design, so the grip can feel lighter, especially when using thicker or non‑MagSafe cases. Glad to hear it’s still useful despite the limitation.

    My first ever magnetic power bank. I don’t like this brand! It slips & slides on my iPhone when I have to move the phone & bank from its location on the counter. Then, of course, it disconnects. Very frustrating

      Hi Cyguy,
      I’m sorry the battery life didn’t meet your expectations. While its compact size makes it convenient to carry, a unit discharging faster than expected may indicate reduced efficiency. If you feel the performance is unusually low, our support team can help check the device or arrange a replacement:

    It’s Ok. Charges but does not last long as mentioned. If used twice in a day it needs to be recharged as would not have sufficient power. Works as efficient as a less expensive brand I have

      Hi Fdemilagros,
      Thanks for sharing your experience. The 10,000mAh capacity typically provides about two full charges for most smartphones, but actual performance can vary based on device power consumption and usage during charging. If you need longer-lasting power, a higher-capacity model (e.g., 20,000mAh) might be a better fit. Your feedback helps us improve future designs.

    Bought this in hopes that it would work to charge a Samsung watch 4 wirelessly, unfortunately it doesn't. Other than that it's great for the price point.

      Hi JayS,
      Thanks for sharing your feedback! This power bank supports Qi wireless charging, but Samsung watches use a proprietary charging standard, so they aren’t compatible with most Qi chargers. Glad to hear it works well for your other devices and offers good value.

      Hi Djaguie,
      Sorry this power bank felt confusing to use and heated up quickly. The unit doesn’t require a manual “off” button—once it’s not charging a device, it will automatically power down after a short period. Our support team can help check the unit or arrange assistance:

      Hi AthenaH,
      Thanks for sharing your experience. Wireless charging is naturally slower than wired charging, and the speed also depends on the power your phone supports. Glad to hear it’s still providing a steady and reliable charge for your device.
