So I have a HP mobile workstation for work that came with a 200W power adapter (19.5V 10.3A) that is quite large and heavy. For travel I got a 150W (7.7A) charger that was compatible with my laptop. Now the laptop is rated for 10.3A. My problem is that even the 150W charger is a pain to carry with me when I travel for work and would like to get a smaller one. There is a 90W travel adapter that supplies 19.5V 4.62A that is much easier to carry around. My question is if the 90W adapter would be able to handle the strain of my laptop when I use it on the road?
