Travellers and replacement buyers

The adapter suits owners of 65 W or 45 W laptops that use the 4.5 x 3.0 mm round barrel and need a spare or travel unit. It also works for machines with the larger 7.4 x 5.0 mm port when the supplied converter is attached. Buyers whose devices require a different connector size or a higher wattage should look at other options.

Round tip 4.5 x 3.0 mm

The DC connector size of 4.5 x 3.0 mm is the single specification that decides fit. If your laptop uses this exact round tip, the adapter will connect; if it uses any other diameter or pin arrangement, it will not.

Questions about this item

Does my laptop need a 4.5 x 3.0 mm round charging port to use this adapter?

Yes, the DC connector is 4.5 x 3.0 mm; the box also includes a converter cable for 7.4 x 5.0 mm ports if your device uses that size instead.

Will this 65W adapter safely charge a laptop that originally came with a 45W power supply?

The adapter delivers up to 65W at 19.5V 3.34A and automatically regulates down to 45W for compatible laptops, so it works with both power ratings.

How can I confirm the adapter is operating correctly once I plug it in?

The laptop should show it is charging, the power LED on the adapter (if present) will illuminate, and the unit should stay cool during normal use.
