So I have this cool 532nm laser out of a laser diffraction decoration light or party thing.. And well I wired it with 3 AAA batteries, turned on and looked to be about 30mw ish in power. I then tried ripping an 18650 out of a power bank. When I tried wiring it up to that it never lit up.. Tried the AAA battery pack and it still didn't light up. Did I fry the laser..?
