Pretty big and bulky. Works fine, but heavy to carry around. Sometimes when magnetically charging it goes off pretty quick. Wish I had bought the smaller version so I could carry it around easier.

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: 👉 https://support.energizerpowerpacks.com/

Dear DarioFC,
Thank you for your feedback. We are glad to hear the wired charging works well for you. We apologize, however, for the issues you are experiencing with wireless charging and the unit's weight. Wireless charging is naturally slower than wired charging. The issue of the unit stopping at 60% is not the performance you should expect. We want to help resolve this for you. Please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so our team can assist you with these issues.
