    Wireless charger is not very impressive. It takes time to figure out the right spot before charging starts. It also heats up quit a bit while charging the phone.

      Hi ShahrukhS,
      Wireless charging can sometimes require careful alignment, and it may generate noticeable heat during use, especially with magnetic charging. That behavior is typical, but it shouldn’t feel excessive or interfere with charging. Removing thick cases or adjusting the phone’s position can help improve consistency. If the heating or alignment issues seem abnormal, the support team can assist:

    Takes quite a while to charge anything. And it, and the phone gets pretty warm when attached. If you use the charge through feature, it and the phone actually gets hot.

      Hi user679106,
      Thanks for sharing your experience. Wireless charging and pass-through charging can generate extra heat because energy loss occurs during these processes, especially when charging two devices at once. If the heat feels excessive or charging speed is unusually slow, please stop using the product and contact Energizer support for assistance:
