Today received the FBE200 and I have started testing with it. In production, I would like to power it from an Anker 6 port 60 watt usb charger. I currently use the Anker device to power a usb hub, a vga2hdmi device and a Raspberry Pi 3. The Anker is much more convenient than multiple power supplies. What is the current draw at 5 volts for the FBE200?
