New gadget alert: here's a four-port car charger that claims to support the USB3 charging spec (5V/3A) and has four USB-A ports, (EDIT!) although "claims" might be a bit strong of a word. They suggest that they support it. I've asked a clarifying question on Amazon. The vendor appears to be directly answering questions there. We'll see.
