How do I share a chrome tab via AirDrop? I'd like to share my current Chrome page on macOS via AirDrop to an iOS device so that I can open it up in mobile Safari.

If I use Safari on a desktop, this is easily done via: Share > AirDrop.

Is there an equally easy way to do this on Chrome?

How to Send Web Pages from Chrome to Your Phone and others recommend using a 3rd party tool called Pushbullet. This is cumbersome because it requires an extension to be installed on desktop Chrome, a 3rd party app installed on an iOS device, and will probably not open the page in mobile Safari (i.e. I'm guessing it'll open it up in mobile Chrome).

Handoff can apparently solve this problem, but that requires you to  be logged in to the same Apple account on both devices. Is there a way that this can work without being logged in to the same device, just as AirDrop via Safari works?
Open the 'File' menu in Chrome, choose 'Share', then 'AirDrop'.
