Can i charge my iPhone 11 with a 20 watt charger?

Heyyy, i got my new iPhone 11 and ....Didn't get a charger out of the box😑

however I had an old charger but then again, the wire was usb-C to lightning, so I had to buy a brick. And while i was on it i bought a 20 watt charger, soo, is it okay to charge my iPhone 11 with it? does it support it?
