This is not a 50000mw (50watts) laser. Just by the burning I can tell that this is a 1-1.6watt laser.

Anything over 2 watts I wouldn’t even use indoors unless you have something to shine it on as a barrier that it can’t go through like a big rock or tile or something and of course with glasses on due to the brightness there will be and because of starting a accidentally fire. Under two watts you can be okay as long as your careful and not holding it at the wall at one spot for any given amount of time and also if you have a barrier which don’t hurt. Under 2 watts you can technically be okay without glasses if your super careful and only shine it on dark things that are mostly black that absorb most of the light but it’s very risky, light colored objects will still be super bright and could cause long term damage overtime, and if you hit something reflective it’s over for your eyes. And ofcourse don’t even shine it and anything living or aircraft’s or other peoples houses as it could hurt someone and get you a felony. Just looking out for y’all.

Which is still ridiculously powerful

I think this laser has 100-500mW not more. The exterior is just Fassade.

Where can I get batteries for it?

How far will the laser ignite?

Cual es su longitud de onda? which is the wave length?

Nah bro thats just 1 watt

Which Batteries 🔋 have you used ? PS: Hello from Germany 🇩🇪

50000mw is a bollocks over exaggeration its 5 watts at best

Never ever it has 50000mW
