      Hi Fuzz,
      Sorry the magnetic hold didn’t feel strong enough with your phone case. This model uses a gentler magnet designed mainly to help align the phone for charging rather than provide a very firm grip. Certain cases—especially thicker or non‑MagSafe ones—can make the attachment feel weaker. Glad to hear it still charges your phone well.

    This power bank is incredibly convenient; it can reliably fully charge my iPhone 17 once—which is more than enough for my needs.

      Hi Chris,
      Sorry the power bank feels so warm during use. Wireless charging requires precise alignment, and when the phone isn’t perfectly centered on the coil, extra energy is lost as heat. Keeping the charger in your pocket also traps heat and makes it feel even hotter. If the temperature ever seems abnormal, our support team can help check the unit:

    Serves the purpose, however, the magnetic part isn't as strong as other competitors, especially when the case is a little bit thick. It may move or fall off when taking out of the pocket which is a little bit annoying.
