Overall Review: There were USB Hubs that had more ports, but I decided to get this smaller one with 4 ports because that was all I needed. It depends on how much ports you need. For me, I am a student who need to charge my phone, my tablet, and my portable charger, so 4 ports was enough for me. Sometimes I do my homework at school or at the library, so I bring this USB Hub along with me so I can plug into wall outlet. It is easy and light to carry as well.
