Question ASUS TUF506QE (MS74) Minimum Wattage

[markdbell]

I purchased the ASUS TUF506QE (MS74), which came with a 180W (20V 9A) power adapter, that I use for work rather than gaming. I have been looking for another compatable power adapter; however, 180W adapters are very expensive. Can a lower wattage 20V power adapter be used (e.g., 150W, 120W, 90W, etc.), since the main purpose fo the ASUS laptop is not for gaming?

Why the need another adapter?

I keep one at home and the other at the office; that way, I can just grab my computer without lugging the power adapter, mouse, etc.
