How is it weak to charge an iPhone when it claims to output 140W for a single device? Is it not negotiating power capability correctly with the iPhone?

First off, the iPhone 18 Pros don't actually charge at 65W. They briefly peak at around 53W, then drop to somewhere around 26–40W depending on the battery level. I just plugged in my iPhone Duo at 64%, and the charger is showing 40W output.

That 6W reading is pretty interesting, though. There could be a bunch of reasons for it, like your iPhone throttling the charging speed due to heat or some other internal issue, a bad cable, USB-PD negotiation problems, etc. Have you tried charging other devices with it? Do they charge normally?

If the issue keeps happening, I'd contact the seller or Lenovo about a warranty replacement. That's definitely not normal.

Edit: I am using this same charger.
