i bought a new ETA-U90EWE Traveladapter from Germany's Amazon.de Marketplace. Now I'm not sure wheter the delivered is original or not.
The original cable weights 24g, the devlivered only 22g. When I load my S4 from my PC with Logilink AA0045 http://logilink.de/showproduct/AA0045.htm and measure the current with CurrentWidget I get 1080mA with original cable. With the new one I only get 840 mA. The new cable is much smoother so more plastic like then the original. The original is more like rubber.
The CurrentWidget shows for both power supplys 1,2 A when Screen is on and 1,9 A when Screen is off, so both power supplys load the S4 with full speed.
The voltage of original is 5,11 V with no load, the new one has 5,04 V.
Weight of the new one is 34gram whereas the original has 35 grams.
I have made pictures. The QR-Codes are different. THe Code from the USB-Adapter from the new one was not recognized with BarcodeScanner App which makes me think.
I hope someone can help me to determine if the delivered power adapter is original or not.
