Sorry if this is already on here, new to this site. I have a laser vortex that runs off 2 "AA" batteries. I want to buy a AC power supply from Ebay so I do not have to swap batteries every half hour. Do I just need any 3 V AC adapter? What rating of A do I need, I see many. I am assuming this is Amps? I can solder this up, just want to get the right one.
Thank you...
