Can you plug a laser level into a Li-ion battery?
This is because there is no control over the flow of power into the battery. It could even cause a fire with Ni-MH or Li-ion batteries. So if in doubt do not plug it in, contact the supplier of the laser level for advice.
Can a DC power adaptor fit into a laser?
Even if it does fit into your laser it may have the wrong polarity. DC has a positive and negative terminal the same as your batteries. Some power adaptors and chargers have the positive terminal as the inner part of the plug and the negative as the outer. Some may be the opposite with the negative being the inner and positive being the outer.
Why can't I plug a DC battery into my laser?
Therefore, even if you have the correct voltage and current it may still not plug into your device. Even if it does fit into your laser it may have the wrong polarity. DC has a positive and negative terminal the same as your batteries.
