Of course, I bought a laser, but I didn’t think that I would have to buy a separate 18650 battery and a charger for it. And I had to do this because the complete ones are nothing more than a set of a young pyrotechnician. As soon as you connect the battery (very light and with a charge of 0.8 V out of the box) to the charger, you will have to go for either firefighters or new pants, because their duet is replete with a whole palette of colors of sparks and sudden musical pops. And this charger is sold separately for 300. Well, he does not climb into any outlet. the name "Fire" on the battery as it hinted, it was necessary to listen.
