      I use a Samsung Tab 4 to control one or two duet wifi printers.
      I simply thought it would be nice if the Tab4 could charge though the Duet2; Would that be safe/possible?
      Is there a android interface program to use when first enabling network stuff for the first time?

      (yes, I realize it would be pretty simple to just have a dedicated charger)

        You could wire a USB type A socket to the +5V and ground pins of either the expansion connector or the PanelDue connector. The Android device shouldn't draw more than 500mA if you leave the two data pins not connected.

          These work really well too and can be wired into the PSU directly.

            Yes, that's a better option.

              I can't do that with a 24v PSU tho... right?

                @ottobawt No that's fine. It's 12v and 24v compatible and reduces the output for usb to 5v. It's also a handy voltage display for your PSU.
