It’s very simple – You have one USB port free and two devices that need to be synced. Do you spend the whole night moving data from one device to your laptop and then to the other one, or do you get the Anker 2-port hub with two Superspeed ports? It’ll transfer data at a sizzling 5 Gbps and you will have wrapped up all the syncing in a few minutes, leaving you free to use your devices. Or snooze.
