i bought a 532nm green laser from ebay,its an aerometal host that takes a 18650 battery.im still new to the hobby,i already had 2 cheaper 532 pens and if i compare the new one is extremely strong,i can see the bean clearly on a bright room from any angle,it can melt-smoke black tape UNfocused and i mesured that it draws 350ma from the battery.so any guess generally how many mw this could be?
edit:
i further tested it what can do with focused beam and is a great burner

Is it one of those laser 303/301 things? If so the output is anywhere from 50-100+ mw with some additional IR.

You can't know without testing but it sure sounds to me like 100mW or more.

Like Razako said, the laser is most likely emitting IR as well, so be careful. I have a cheap 532 which takes a 18650 battery and is 100-150mw max. If yours is stable then most likely around 100mW. Have you watched Styropyro's video https://www.youtube.com/watch?v=woiTedSKPrk as it could give you a hint to what power your laser is without spending out on an LPM.

at night i can still see a visible beam from all angles even if i wear protection glasses
WHAT!!! You can never see the beam with safety glasses on, you can only see the dot. You are using the wrong safety glasses! They are useless with that laser.

I got one of those 532nm <5mw lasers from that shadowhawk company, look just like the ones in that ebay link, however the first one they sent me was DOA, so they sent me a second and it is definitely 5mw or less. Cant see the beam even in the dark, and it starts out dim then after a minute or so the dot gets brighter. So I called and demanded a refund, which they gave me, and I turned around and bought a Sanwu Pocket(which I got a shipped email for yesterday :D). Still have the 532 cheapie. Has good range but its weak. I don't feel anything from it on my skin. Must have been a scam. Because it was advertised to be a burner. So buyers beware of shadow hawk green lasers. total scam, as they charge 56$ for it
