VoltMe make a 140W GAN charger, which I didn't try. Instead I replaced my Asus G14 (w/RTX3050) 180W brick with their 65W GAN USB-C PD charger and it provides ample power for regular non-gaming use. When momentarily going over 65W the battery is called to the rescue but it gets recharged quickly enough afterwards to maintain a comfortable margin. I very much appreciate the weight difference when travelling.
