I don't know what's up with mine , but it takes 3 hours on "A" device to fully fast charge my little park flyer's 7 cell, 600 mah battery. At that rate, it's useless as a field device. I wish I could contact the manufacturers, but we all know the deal here. Otherwise, it suits me as a home based unit when I'm not in a hurry.
How many ports do you have programmed? If all 4 are programmed then the max charge rate is about 250 mA and it would take 3 hours or so to charge a 600 mAh pack. Make sure only one port is programmed and you should be able to charge it in well under 1 hour.
