any wattage above what it asks for on the new devices is fine, won’t hurt. less wattage won’t charge fast enough and it will complain. 65w is pretty standard for 14" laptops, 90w is recommended and will work on more devices in case you have one that requires 90w, usually 15.5" screens or larger, 130-180w for docks and gaming laptops. 240w for special scenarios. pick your poison, don’t go unbranded shitty universal ones, get a good genuine oem adapter, the 90w runs about $40 new on Amazon, 65w $22
