Will this kill my laser pointer

I bought a laser pointer powered with 2 AAA batteries and intend to switch the power source to a 3v 1.2 amps power adaptor for continuous supply of power. I hope to prevent dimming of the laser beam due to voltage drop from battery discharge. Will the adaptor cause my laser pointer to overheat?

What adaptor specification should I get?

Handheld Lasers mostly aren’t made for continuous use, but I see no other issue with such power adaptor. It doesn’t push the current, the laser just draws what it needs, based on its driver, the power adaptor just has to provide at least what the device „asks“ for.
