JetStar via Walmart offers the Keedox Powered 7-Port USB 3.0 Hub, model no. CG121-Keedox, for $14.99 with free shipping. (Amazon charges the same.) That's the lowest total price we could find by $5, although we saw it for $8 less in July. It features a 60-watt UL certified adapter, four USB ports, and three dedicated smart charging ports.
