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.
