First off, I don't know if this is the right thread. I think it is so I'll keep going. Haha. The question is, Do any of your handcranked radios or flashlights make a whining noise when you are charging them? I bought a radio/flashlight set and when I am cranking them, there is a whining noise. I don't think this is safe as it could alert others to my position. I am just wondering if this is common with all handcrankers or just the cheap ones. Any thoughts?
