#1 Is charging the camera battery through a separate battery charger, or directly to the camera?
The charger is about 3.5 x 2.5 x 0.75 inches. The battery life could be better (I have 3 batteries and would take them all for a week trip). Also, my camera died on my first water experience so test prior to departure and have a backup if pictures are really important to you. I bought the camera in July, 2012 and on July 18, 2012 it was dead. I'm sending it in for another repair - the tiny latch that holds the battery in place broke and most of my pictures are not in sharp focus since I got the camera (it definitely does not do well if there is action in the shot). I find that I'm terribly disappointed in this product - DO buy the extended warranty through MACK camera if you can. I wish I had chosen a different camera although I am really pleased with the video aspect of the D20.
