You can use a 60 Watt adapter, but it will not fully charge the laptop while using it. Asus sells a USB C 40watt charger that plugs into the USB C port - it more or less acts like an external battery prolonging your gaming without the 90watt brick. 60Watts will do the same, but you run the risk of damaging your battery over time.
Sorry, there was a problem. Please try again later.When running Linux (Ubuntu 19.10 specifically), which has very poor NVidia power management support, system idle power is around 20 watts. I've managed to achieve 15 watts once by forcefully depowering the GPU, but with stability/functionality issues. Windows 10 power management for laptops with NVidia hybrid graphics is usually much better (I've seen estimated battery life of over 5 hours in Windows, never above 3.5 in Linux) In Linux despite the heavier standby load, the laptop seems to charge even when in use with a 60W PD charger (Nekteck power delivery desktop unit), I have not tried with a 45W charger such as my Nekteck car power supply. When the laptop is suspended, both of the above mentioned chargers WILL charge the battery. I am currently on vacation (very light usage) and I still haven't pulled out the original charger, the Nekteck has met my needs for both keeping my Pixel 4 XL and this laptop charged. But since we're pretty busy outside of the hotel room, I'm not using it much at the room. Usually less than an hour each evening, but putting it on the Nekteck before bed gets it back to 100% without issue. With a 30 watt Ravpower 26.8AH power bank, the laptop will not charge, although it appears like the battery drain rate slowed down and estimated usage time increased. I won't be able to retest that for at least a week.
