USB Backflow

[W4EMS]

Powering SDS100 with USB to a hub with 2 ports. 2nd port iPhone. If primary power to hub is lost, does the SDS100 battery charge backflow into the hub and back to hub power input and/or iPhone?

Random late night thought.

Unplug the USB hub from the power source and look at your iPhone to see if it is still charging. Your USB hub or the SDS100 may be designed to prevent that, but it is an easy test.
