I have a Dell 5401 for work, same story with USB-C charging. Its power brick is 90W but the USB-C block I have can only do 60W max per port. Windows will whine

I have a Dell 5401 for work, same story with USB-C charging. Its power brick is 90W but the USB-C block I have can only do 60W max per port. Windows will whine about a "slow USB charger connected" but other than that it works fine for the typical MS Office stuff. It will drain if I really push it though.
