    I bought two. It was working great until now...I only had this for close to two months now and the battery is bad...both batteries- I been charging it for more than 12hours and it is won’t charge at 100%. It only charges to 3bars. The button that lights up to indicate how much has been charged is stuck so I can’t tell. I have to charge it in order for it to briefly light up and let me know. Do yourself a favor and look for another portable battery!

    This item does not work. I’ve tried to charge it to see if that was the problem, so I did, and the portable charger still wouldn’t work. I got this for my Apple HomePod Mini that I had purchased from you guys, because the HomePod Mini is not wireless.
