The power which they use is from alkaline batteries and it varies from 100 to 150 mW which is very powerful for a laser pointer, indeed. They are and convenient and their design is smart and refined, too. The keychain attached to some of them is also a kind of advantage. Some of are designed to be used also as a flashlight so that gives the owner felling for safety and convenience.
