Default Is this for real???

Could this violet laser from DHGate.com really be 5,000mW?

5000mw 405nm Purple-blue Violet Laser Pointer Focusable Burn Black Match Cigarettes+Battery+Changer+Box+$24.09 | DHgate.com

Also isn't violet the best color for burning? I'm trying to find a good burning laser.

The real power of the laser might be less than 10%, making them unable to be burn things.

The diode alone costs many times that price for that much power.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.

A charger, batteries, and a laser for 25$. These days a pair of decent quality batteries costs more than the whole package.

No, the laser will be nowhere near 5W. Are you looking for a quality laser, or do you want it as cheap as possible?

If I bought that laser I'd be hoping for about 25mw, though it could actually be more or less.
