PowerCore Fusion Passthrough Question

I am aware that the PowerCore Fusion allows for passthrough charging for your devices when it is plugged into the wall. However, it has not been made clear to me whether or not this is allowed when you are recharging the Fusion via the microUSB port. I’d appreciate any clarification. Thanks!

My guess is yes but as the limiting factor is the speed of the charging circuits in the Fusion you’d be better off recharging the Fusion from one output (say of Powerport4) and recharging devices off the same Powerport4 and not via the Fusion. The charging of Fusion is like 10.5W vs Powerport4 40W.
