I was pretty disappointed that it wouldn't work at all

I was so excited to get this Charger as a friend had one and raved about it. I have only had it since early March and maybe used it 3 or 4 times. Last week (early April) I went on vacation and took this thinking I would be covered in case I didn't have places to charge my phone (airport, not enough outlets, etc.). I was pretty disappointed that it wouldn't work at all. The battery pack is fully charged and neither the lightning charger or the auxiliary port are working. I didn't drop it, get it wet or anything. It stayed in a pocket in my purse and that was the only thing in there. I have zero idea why it stopped working and so I just got back from vacation and missed my window on returning it. I gave it two stars because when it worked it did a great job. Update. I guess I must have gotten a defective one. Ugreen read my previous review and replaced the defective product even though it was outside of the return period. Thanks
