Questions about this item

Will this 90W USB-C adapter charge my older HP laptop that only needs 65W?

Yes, the adapter delivers 90W and is compatible with lower power requirements including 65W, 45W, 30W and 29W devices, so it will safely charge your older laptop.

How can I confirm the adapter is delivering the correct voltage to my Spectre x360 after plugging it in?

The adapter provides fixed output profiles of 5V at 3A, 9V at 3A, 15V at 3A and 20V at 4.5A; your Spectre x360 will negotiate the appropriate profile automatically and show charging status on screen.

Does the package include both the USB-C power brick and the AC mains cord, or must I buy the cord separately?

You receive one 90W USB Type-C power adapter and one high-quality AC power cord in the box, so no separate cord purchase is needed.
