Wow, shipping is cheaper from Asia than when I bought from USA to USA.

I ended up buying a Plugable USB 2.0 7-port HUB 60 WATT. http://plugable.com/products/usb2-hub7bc/
You can run three Moonlander 2 on these if you want. I'm using with GekkoScience 2Pac at 200 Mhz and running fine. My KillAWatt device is showing it is drawing 12 watt from the wall.  Running my USB Tester shows 4.85V 1.92A (9.3W). It should work fine for Moonlander 2.
