It would halve it or worse. ASUS makes a few models with built in internal batteries which work quite well.
The type that latch onto your existing laptop display are really not great. They put a huge amount of extra force on the hinge where tons of sensitive ribbon cables live and you are severely limited in viewing angle. Not to mention you can’t move the monitor around in a tight work space or disconnect it easily to hit the field.
A standalone portable monitor is the best solution IMO. The nicer models come with adjustable stands, protective travel cases, and USB-C DP pass through functionality.
Shoutout to the libs wetting their pants over non-Russian weapons being used against Ukraine
I’m not sure what could be worse than literally bulldozing all of Palestine to the ground and killing the survivors that crawl out. And that is not hyperbole. Literal bulldozers are going in a line through Palestine.
Maybe PugJesus can enlighten us?
