I used this to replace the 19.2v power adapter on my Samsung tablet which I always use on my tumble dryer/treadmill. You will get a series of tips and a blue screen will show the power and USB voltage. I didn't have any settings, I just mounted and plugged in the tip. It's well done, better than the original in my opinion, although the blue info screen is prominent and bright, but I fixed that by turning it upside down, cheerful-cheerful. I really like its setup, unlike the factory adapter with a light that glows when plugged in whether the tablet is powered or not. It doesn't indicate a bad connection either, but seeing the measured voltages is reassuring. Good quality, arrived well packaged and still working as of my last review. highlighted.
