The barrel plug measures 4.5 mm by 3.0 mm and fits the centre-positive ports on the supported HP Stream, Pavilion and Spectre x360 series. A two-pin IEC input cord is supplied for wall connection. The compact brick measures 3.7 in by 1.5 in by 1 in and weighs 0.6 pounds.

45 W output limit

Maximum output is 45 W at 19.5 V and 2.31 A, so the adapter cannot power devices that require 65 W or higher. Input accepts 100-240 V at 50-60 Hz for worldwide use. Buyers needing more wattage should select a higher-rated supply.

Questions about this item

What output does the 4.5mm × 3.0mm barrel connector deliver?

The connector supplies 19.5V at 2.31A for a total of 45W, matching the laptop's DC input requirement.

Will the 3.7 in × 1.5 in × 1 in brick fit in a slim laptop bag?

At 0.6 lb and those dimensions the adapter slips into most accessory pockets without crowding other gear.

How do I connect the two-pin AC cord to the adapter?

Plug the figure-8 mains lead into the brick first, then insert the blue-tip barrel into the laptop; reversing the order can leave the cord loose.
