After a few months, it makes noise and no longer charges the tablet at the speed it used to charge it initially (from 2 hours, now it takes 11 hours to fully charge).
The original Samsung charger charges it normally in 2 hours

Attention! There are also copies that do not meet the specifications. I gave it four stars because the genuine product is likely to be very good and I didn't want to downgrade it. However, when you receive it, you must necessarily scan the QR code on the device to make sure it is genuine.

Reliable and powerful charger. With the Ampere app, I measured up to about 2000 mA in wireless and wired charging on Mi 9.
