    Product works well. The battery is big enough to charge several phones at once to full battery. (From about 20% on 2 iPhone 15 Pro Max phones) Had plenty of battery left for a future charge.

    After using this product for over three months now, I can say it was worth buying. It has good quality and charges quickly. The one issue is that it takes more than three hours to fully charge, but this is understandable given the size of the product.

      Hi Janet,
      Thanks for sharing your experience. We're sorry the weight was inconvenient and that it didn’t meet your expectations with Apple Watch charging. This model does not support Apple Watch charging — it's designed for smartphones and Qi-compatible accessories only. If you’re still within the return or support window, we recommend visiting our support page for further assistance:

    bought this before the hurricanes and it was a big help during power outages. Bought 5 more for christmas gifts and and seemed to be something each person felt they could use immediately in the car in particular.
