So for those who cant watch
little size, middle price battery gets 5 hours with max bright /wifi on / medium sounds , 5.50 min with half bright
middle size, cheap price battery gets 6-7 hours
big battery gets 10-12 hours
these are without using switch own battery so add 2 hours and 20 min + big battery you can get something like 15 hours straight . Amazing , though they look like xbox 360 power brick
