Nonsense. We just need...about 10-15 USB-C laptop charging blocks rated at 100W each. I'm sure can find a 1:10 USB charge splitter (heck, maybe we just need to get creative with a few 1:4s) on Temu.
Or, in the pre-USB-PD days, you do this[0]. Only 30 USB ports required. I swear I remember this being a toaster instead of a hot plate, but I guess you would need around 300 USB ports for a toaster.
