I know that the Apple plug that comes with an iPhone (the white cube) is dual voltage and you do not need a converter when using 220v (like in Europe). My question is, if I have an adapter (not a converter!) that plugs into a European outlet and has a USB-A port in the adapter, can I charge my iPhone using a regular lightning cable WITHOUT the Apple plug? That is, is the iPhone itself dual voltage capable, or will charging this way fry it?
iPhone X, iOS 12
If your adapter is a reputable brand you should be fine, I do this regularly. As Phil says, the USB port pushes out 5 volts regardless what AC power is supplying it. The only risk would be a cheap and nasty no-Name or counterfeit adapter which doesn’t supply clean 5v.

The dual or multiple voltage support only applies to AC current. ie the current coming from the wall outlet.
The current coming from any USB port, will be DC current, which will normally be 5v. There is no other current coming form a USB port regardless of what its plugged into.
So the question is, does the adapter you are planning to use provide 5V, at 5 or more watts and 1 to 2 amps through the USB port. If the answer is yes, then you can use it.
Is iPhone X itself dual voltage
