This green laser pointer is one of our promotional products, which has passed FDA & certifications. It comes with high power, standard 520nm wavelength, and circuit optimization. Although the product size is small, the stability is better than most green lasers, and you don't need to worry about overheating or overvoltage. Due to size constraints, our recommended maximum power is 100mW. The USB charging port is available so that you can charge it directly.
