      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:

      Hi Picture414,
      Thanks for your feedback, and we're sorry the charging speed didn’t meet your expectations. This power bank supports up to 20W USB-C PD fast charging and 15W wireless charging, but actual performance can vary depending on your phone model, cable quality, and usage conditions. If your phone shows “slow charging,” we recommend using a certified PD-compatible cable and confirming your device supports PD fast charging.

      We’re sorry to hear this power bank didn’t meet your expectations. The thin cord and the need to lay your phone absolutely flat likely relate to the Qi wireless charging design, which requires precise alignment and stable contact between the phone and charging surface. Any tilt or uneven placement can interrupt charging.

    This power bank seems to offer great specs at a great price. It’s a sham. Within ten days it has become nothing more than an ugly paperweight. Although, given the magnetism, I suppose it could be used to hold paper clips or bunches other small metal objects. Fully charged it prior to first use. Once fully depleted, it was recharged to full again and then used to full depletion once more. Since then it has not held a charge at all. The LED lights indicating charging have changed to an unknown pattern not discussed in the manual. I reached out to Energizer support five days ago and have yet to receive any reply. Save yourself the frustration and buy a power bank made by a solid brand like Anker. Those have never failed me.
