Charging options

So I have 4 devices ( 2 move controllers, farpoint gun, gold headset) that I need to charge, but need my USB ports for the gold headset receptor and my external hard drive. Can anyone suggest a good option for keeping these charged and not having to constantly switch stuff around?

Also, my dual controller charger has a feature where it stops charging the controllers once they are fully charged. Having something with a feature like that would be good to prevent the batteries from dying out too quickly.

Thanks!
