Questions about this item

What does the 90W output mean for a laptop that draws less power?

The adapter supplies up to 90W at 18.5V and 4.9A; a laptop drawing less current will only take what it needs, so the unit runs cooler and within its rated capacity.

What does the 5.5x2.5mm barrel connector limit in practice?

The 5.5mm outer and 2.5mm inner diameter barrel plug fits only laptops with a matching jack; it cannot be used with smaller or larger barrel sizes or USB-C charging ports.

What clearance does the adapter body need to sit on a desk or mount behind a monitor?

The brick-style body requires a flat surface or shelf with enough depth for its length and cable bend radius; no mounting brackets or VESA holes are provided.
