Whenever we get a charging device, we like to start with the math. Limitless Innovations sent their ChargeHub 7-port USB charging station; its power transformer is rated for 44 Watts, roughly 1.2 Amps per port if they were ever all pulling down all they could; in real life, with most ports pulling more nominal draws, some of the ports could pull as much as 2.4A. That’s good service, a lot better than we’ve seen from many USB power products. With this, of course, there’s a plus in having 7 available power ports all in one place. Bottom line: the Limitless Innovations ChargeHub offers USB charging to the seventh power.
