I tried this green laser module at 3 volts, and it appears to draw about 200-300ma (I say "appears", because I don't trust the meter in my PSU), and it gets quite warm after a few minutes of usage. The case is metal, and that helps to dissipate the heat. The focus ring has a spring under it, as the pictures in the listing show, and it is actually quite stuff, so you don't need to worry about it being bumped, and changing the focus, because one you set it, it's not going to move. There is a small hole on the side of the case, and I wonder if this for the charge LED, for internal batteries, in a different configuration. The only bad thing I can say, is this comes with no documentation. The listing says 3 or 3.7 volts, but glancing at the regulator circuit, I suspect it can work with a much wider range of voltages.
