I bought this AC adapter as a backup for the AC adapter that came with my Samsung Notebook9 laptop. "Brick" is slightly larger than the original Samsung adapter, but only about 1/4 inch. The USB-C connector is actually a bit smaller. It fits snugly into the USB-C port. I compared the "time to full charge" with both the Samsung cable and the replacement cable, both showed the same time. I also use it to charge my Galaxy Tab3 tablet and when plugged in it reports it as 'Fast Charge'. As I only received this yesterday I can't confirm the overall quality at this time but for now I'm happy with the purchase.
