Here's a picture with both chargers. Left is the Galaxy Tab S's. Right is my phone's. They appear to have the same values, I still ask because I noticed its taking a long time for the tab to charge.
I dont know if its useless but when T700 is connected to my pc it show 476 mA , connected to my original charger it shows 1800 mA and connected to my 1 amp phone charger it shows 745 mA.
The values that I expected.
From the makers site I learned only Maximum value is important.
