It should take about an hour to charge. Maybe longer if you plug into the computer. If they double load onto your computer, you can highlight and delete the duplicates. You can press control while clicking to highlight more than one or click and drag the mouse to highlight what you want. I will look up to see if there is a way to delete all on the camera.
thank you ! I am charging it in the wall. Didnt know it charged on the computer. red light blinking
