More flies with sugar
Honestly, the LEDs in these things require so little power that practically any outlet to USB adapter will do the trick. I use several of that 7 port option you have posted above on the left. All off of them run off the same plug; lighting up well over a dozen fusion reactors powering my Hot Toys with a couple of statue LEDs to boot. It's an inexpensive option and you can disengage each USB connection individually (though admittedly I found the switches to be cheap and prone to breaking). Additionally, the hub looks like it comes with a more than capable AC/DC adapter.
Hopefully that helps.
