I purchased this item when you posted this on sale last October. It worked good for couple months. Now it takes 4 days to charge it full. I also got this other charger that you posted at earlier time and this one only takes few hours to charge and still going strong https://www.amazon.com/IMNEED-10000mAh-Portable-External-Smartphones/dp/B0154Q1MGA/ref=sr_1_1?ie=UTF8&qid=1494264421&sr=8-1&keywords=imneed+10000mah+power+bank.
