Adapters and converters are two different things. Adapters are fine for things like portable smart phones and even laptop computers or I-pads that can safely run on 220 or 120 volts. Converters do the adaptation and also power down from 220 volts to 110 for devices like your iron and typically provide connections so you can plug in multiple devices to recharge. So, converters are all-in-one products like you want. Look on Amazon and you will find multiple choices for about $30 - $35 USD. Better yet, support your local travel store if you have one.
We take a converter with us because we take our waterpick. The converter is 1” x 2” x 4.5” and with a single plug into a wall outlet in a hotel room, it offers us 3 US outlets, 3 USB outlets and 1 USB/C outlet. So even in a hotel room with limited outlets, we can easily and simultaneously charge 2 cell phones, one portable/pocket charger, run the waterpick, and charge one or two other items, like an electric toothbrush.
You want to be sure when you go to Europe that you take the right plug adapter that comes with the converter for the wall socket in your hotel room. England uses “G” plugs. France uses “C” and”E”. Germany uses “C” and “F”. Italy uses three different ones: “C,” “F” and “L.” See https://www.worldstandards.eu/electricity/plug-voltage-by-country/
When you buy a converter, it should come with an array of plugs for you to pick and choose from as you pack for your trip.
