(verify)
Assume that standby showing video and/or charging takes under 0.5A, and charging while previewing, or active recording, can take nearer 1A. It may be 0.7 with simpler settings (e.g. lower framerate, resolution, hypersmooth off).
The recommendation for a 2A power supply seems not to be because it uses that much, but to be a safety margin that makes you buy better quality ones, rather than the nearly-lying crap that is honestly a lot of them. (...but I'm not sure, there are details that may vary with)
Batteries for various models are around 1.7Ah, so expect maybe 90..120 minutes of recording under simpler settings, maybe half that with maximum quality.[1]
Charging should take two hours, on a dedicated charger (inside a GoPro it may take more - or the same two-ish hours with a good USB power supply - GoPro themselves sell one, which may be a little overpriced but seems a known good quantity).
It seems that on USB power, you might get either recording (while on) or charging (while off or previewing(verify)), but not recording and charging at the same time presumably a decision based on considerations of heat and/or power source capability?
As such, there are footnotes to using it as a long-term dashcam or perpetual webcam, to the sound of 'not guaranteed by gopro, but there seem to be ways'.

Can you power the thing through USB without the battery? (a.k.a. passthrough power)
On many models, yes. Note that you need the power source, and the cable, to be able to carry enough current for whatever you're doing.
It needs to be able to comfortably supply 1A. Recommendations are for things more capable than that.
The GoPro itself seems to do a basic test (illustrated by the fact you can disable this ), though I'm not sure whether this is a charging protocol thing or a voltage depression test.
In some ways USB without battery will also run colder (because there's no charging going on) meaning less risk of heat-based shutdown, though note that a stationary GoPro (wedged into a setup) doesn't get air-cooled as much as the designers may have assumed so that's not a guarantee.

Use as webcam
There is a "GoPro Webcam desktop utility"[5].
It talks to the GoPro over USB, though using some custom faff to do so, instead of being a standard UVC device, which also takes over control over the GoPro in a way that isn't fully integrated with everything else. It will absolutely act as a webcam and if that's enough you're good - but it doesn't seem to pick up the same camera settings (e.g. ISO) you set in the video mode, you may not get remote control at the same time, and other such details.
Also, in my experience this was not very reliable - it would sometimes stop communication in a way that only a reboot seemed to fix
