I am trying to external power a keychain laser.
Using a 4.8 volt power supply, once I power up the laser it does not shine near as bright even if I switch back to the 3 1.5v watch batteries. It's like the laser is now faulty. Tried this on 2 lasers so far.
Does the laser voltage have to be exactly 4.5V?
Thanks.
