gaming laptops are pretty much scam anyway, as person “once” fall for such scam.

• they are really heavy, not really good with travel.
• they are also power hungry, might be less than your actual tower rig, but significantly more than common “business laptop”
• the battery won’t last with degradation where you constantly plug it in.( to gain the boosted frequency where you can play games at higher settings/frame rate)
• your upgrade path is very limited and they won’t have the parts after like 2~3 years.(so anything broken you have to try find it on ebay/amazon/aliexpress)

for portable gaming during travel, your best choice is consoles. So switch, steamdeck, heck, even PS4 slim is better than gaming laptop.(hopefully PS5 pro/slim is made into form for easier box/travel format.)
