Dell 65W 4.5 mm Blue Tip AC Adapter
This Dell-branded adapter delivers up to 65 watts through a 4.5 mm × 3.0 mm barrel connector with a blue tip. It is built for HP laptops that require a 19.5 V, 3.33 A supply and also covers 45 W models. The unit ships with a detachable mains cord and carries CE marking.
Thermals noise and power draw
The adapter accepts a universal AC input of 100–240 V at 1.5 A and 50–60 Hz, so it runs from mains supplies worldwide without a voltage switch. Under normal load it produces only a faint hum and stays cool to the touch thanks to its compact switch-mode design. Short-circuit protection limits current if a fault occurs on the output side.
Build quality connectors and daily use
The barrel plug uses the blue-tip 4.5 mm standard found on many EliteBook, ProBook, Envy, Pavilion x360, Spectre x360, Stream and ZBook models. A rugged strain relief at both the brick and the plug resists cable fatigue from frequent packing. The package includes the adapter and a standard power cord, but buyers needing a USB-C power delivery port or a second simultaneous output will need a different solution.

Questions about this item
How do I install the 4.5 mm Blue Tip connector without damaging the laptop port?
Align the Blue Tip straight with the 4.5 mm DC jack, insert firmly until seated, then connect the AC cord to the brick and plug into a 100-240 V outlet; forcing the tip at an angle is the step people get wrong.
What maintenance will the adapter and power cord need later?
Inspect the barrel connector and cord for fraying or bent pins every few months, keep the unit in a dry, cool place, and replace the cord or adapter if the 19.5 V 3.33 A output becomes unstable.
What limit appears first during sustained 65 W charging?
The 1.5 A AC input rating and 65 W DC output cap are reached first, so the adapter will not sustain loads above 65 W without triggering its short-circuit protection.
