I've been using the official Motorola micro USB charger but I'd like to be able to charge multiple devices at the same time, like my Bluetooth speaker as well as my DROID X. I think it would be nice to also have more ports available like if a passenger wants to charge something, too. I know there are lighter socket adapters that just have two USB ports at the back. Do you have any particular recommendations? I'd like to have like, four if possible but two is at least better than one (and more flexible).
Another idea I had is to somehow integrate a cheap little four port USB hub to the deal.
Anyone tried anything like this? Does the hub "dilute" the power too much?
