    This power bank did not charge wirelessly. I have tried to contact Enerzier for support but no help. The direct me to a a Manufacturer and not help at all. Do not buy Enerzier brand. I used Anker and they stook behind their product. ANKER is the way to go.

    The magnetic recharger works well with my iPhone16, but I haven't tested the other ones yet. It is relatively heavy.

      Hi LaurenB,
      We’re sorry to hear about the slow charging and heat issue. Wireless charging and high-power output can generate some warmth, but if it feels excessive or the speed is unusually slow, it may indicate a problem. Please ensure you’re using a compatible adapter and cable, and if the issue persists, contact Energizer support for assistance or replacement:
