The adapter delivers 45W through USB-C with profiles of 5V 2A, 12V 2A, 14.5V 2A, 15V 3A and 20V 2.25A, matching the original 492-BBUU specification for the Latitude 7275.

How can I confirm the 492-BBUU adapter is operating correctly after plugging it in?

The unit is UL, CE, FCC and RoHS certified and tested for correct voltage, circuit protection and stable current; the laptop should show charging at the negotiated USB-C power level.

Does the 492-BBUU package include a mains cable or only the USB-C brick?

The product is supplied as the 45W USB-C adapter brick that replaces OEM 492-BBUU; a compatible AC mains lead must be sourced separately if not already owned.
