i was looking for a good quality power bank and thought of giving this one a try. im glad i did. it works so well i bought another one. the shipping was perfect protected the bank well comes with easy to follow and read directions. the bank itself is light. although my samsung galaxy didnt charge without a cord wasnt an issue for this price. the cord comes with it to charge it which it charges completely in a few hours. i can charge my galaxy 8 several times before it dies. it charges my cell very fast which is good as i am not home for over 16 hours a day and use my phone constantly. i would recmmand this charger to all my friends and anyone looking for a light perfect powerbank.
