Questions about this item

What does the 19.5V 16.9A output cap in practice?

The adapter delivers up to 330W, so it caps at the laptop's maximum draw; it will not force more current than the device requests.

What physical dimensions must the laptop's DC jack match?

The barrel plug measures 7.4mm outer diameter by 5.0mm inner diameter with a centre pin; the jack must accept that exact size.

How is the adapter installed, and what step is often missed?

Connect the IEC power cord to the brick, plug the barrel into the laptop, then attach the cord to a 100-240V 50-60Hz mains socket; the step often missed is seating the barrel fully until the centre pin clicks.
