My phone charges quickly from its wall adapter, but much more slowly when I plug it into my USB-C desk hub. The hub is also connected to a monitor and a couple of peripherals, so I can’t tell whether the phone, cable, or hub is setting the limit.
Which specifications should I compare to work out where the charging speed is being reduced? Does a hub’s advertised power delivery mean that full power is available to a phone while the other ports are in use?
