The 6 ports make the all-in-one to charge tablets, mobile and everything that has a USB port.
For my part, I rebooted my mobile Samsung Galaxy, a tablet of the same brand and V-Tech tablet of my daughter and the Nokia Lumia my husband: ràs, super fast, ports are quality and the load occurs silently.
In summary, a convenient charger and quality easy operation. RAVPower My compliments!
