So I’m guessing the USB port on my laptop has the bare minimum of current flowing through it. When I connect my 7750 to it, it’ll charge two bars worth over an eight hour period. If the battery’s drained, that’s about enough power to last the night with minimal radio usage.
This morning I plugged the cradle into the wall charger, and had a fully charged device in less than two hours. I think I know how I’ll be managing things going forward. Maybe it’s time to invest in an externally powered USB hub.
