Unlike the original charger, it does not carry the fast charge logo. And once on the area to check it, disappointment is immediate. While the original charger offers really 2 A output, this one can barely get 150 mA! Besides, the phone does not show "fast charger connected." In the end, the phone slower load with this "feeder" on a computer USB port, a shame.
Last detail, the ETA-U90EWE charger (reference written on the receipt) is usually supplied with a 1.5 m cable as indicated on the Samsung site. There he does not even 1 meter. Product non-compliant, non-Samsung packaging and wacky features. I can only advise.
