I know there was a short thread on this topic before, but I can't find it in numerous searches! The first time (and maybe the second time) I charged my range extender it worked just as prescribed... Solid yellow while charging, solid green when (supposedly) fully charged... And it always showed the 100% on the vision app after charging to the green light. Now it still shows the yellow LED while it is charging, but it seems to charge "forever!" I charged it for at least 4 hours yesterday waiting for the green light. Today, wanting to resolve the issue, I turned everything on just to see what the Vision App said about its state of charge and it reported 100%. So I plugged the charger in again and it is still showing the yellow light... And I've had it on for 20 - 30 minutes now with no green! So I was reminded of the poster a few months back that said his extender would not charge subsequent to its first charge, and I am wondering if this is what he meant. It's not a big deal, since the charge in the extender seems to last a long long time, but it is still bothersome (and may be indicative to a future failure) that it doesn't work as claimed. I really don't want to overcharge it. So does anyone know how long the extender should take to charge? I seem to recall that the first time I charged it it took no more than a couple hours, but it may have been partially charged already.
