High-Power Blue Laser 50000mW with USB Charging. New!

High-power blue laser 50000mW with USB charging and built-in lithium battery. Wavelength: 450nm. Includes USB charging cable. 5 focus-adjustable light-effect adapters. Safety cap to prevent accidental activation. Also functions as a power bank. Length: 21 cm; width: 4 cm. The device is new—I used it only once for testing. Hand delivery available in Barreiro or Lisbon. Shipping worldwide via postal service; shipping costs borne by the buyer. WARNING: This is not a toy. At short distances, the laser beam generates sufficient heat to ignite fires and cause burns. It can cause severe eye injuries even when reflected off reflective surfaces.
