I don't know too much about USB-PD. I understood that USB-PD requires negotiation between the charger and the receiver. So probably my Windows laptop (Dell XPS 9570) should be able to know the current wattage input it's receiving. Windows probably also know since it's popping up saying slow charging. So I'm curious to know what wattage is my Dell is getting and is it getting the 100w it supposed to get?
My setup is a Dell XPS 9570 connected to Razer Core X Chroma eGPU. I've tried two cables, the Thunderbolt that came with the Razer Core X and the Apple Thunderbolt 3 0.8m, both of them still give that slow charging pop up.
