    It has trouble sticking to my phone, but it's a good charger if you want something fast; this works.

      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 wireless charger charges good but the idea of this kind of charger is to hold on to your phone with the magnet, which is practically nonexistent. You have to lay the phone down on the charger and not move it or hold both together without letting go or the charger comes loose from the phone. Disappointed, especially for the brand name.

      Hi JackL,
      We’re sorry the magnetic hold didn’t meet your expectations. This model uses a slim design, so the magnet strength can feel weaker compared to thicker MagSafe chargers. For better grip, make sure your phone case is MagSafe-compatible or try using the power bank without a case. If the magnet still feels inadequate, you might prefer a higher-capacity model with stronger magnetic alignment.

    Had to return it three times. One not working at all, another one, the USB-C charging cable included is too tight to the point that it damages the internal connector of the product (do not use the one provided, other quality cables work just fine). The third time, the product made a humming sound as well as a sparkling one.
