The multi-talented Family RockStar provides an enormous 5.4 Amp total charging power across four USB ports. That's enough power to charge two tablets and two smartphones, all at the same time. Any port can charge any device thanks to an intelligent smart-chip, which recognizes the connected device automatically. For tablets that means optimal charging at 2.4 Amps. Wall-mountable and boasting a ten-foot cable for convenient placement, this charging hero will make power struggles at home a thing of the past.
