2 Pack Rechargeable Green Laser Pointer 532nm Visible Beam Light 1mW Class 1 Adjustable Focus Aerometal 14cm 18650 Battery Smart Charger Presentation Teaching Astronomy Outdoor Camping Hiking Signals

Enhance your presentations with this two-pack of rechargeable green laser pointers featuring advanced optics and durable construction. Each pen measures 14cm and is crafted from aerometal material, providing a lightweight robust body that fits comfortably in pockets for daily carry. The 532nm green light produces a clearly visible continuous beam at 1mW power output with Laser Class 1 safety rating, ideal for pointing at projection screens, whiteboards, and video monitors during classroom instruction, business presentations, and seminar demonstrations. Astronomy enthusiasts appreciate the precise beam for navigating the night sky and identifying stars, while outdoor adventurers use it for camping, hiking, and signaling activities. The adjustable focus mechanism allows you to rotate the head and change the beam spot size, achieving focused points or wider coverage up to 6 meters with spot sizes under 10mm. Each pointer operates on one included 18650 rechargeable battery with working voltage of 3.0 to 3.7V, delivering consistent performance after a brief preheat under 3 seconds. The package includes two green laser pens, two 18650 batteries, and two smart chargers with indicator lights that blink red during charging and turn green when fully charged after 3 to 4 hours. A convenient ON-OFF button requires continuous pressing to maintain power, while the included key lock ensures secure operation. Before first use, remove the plastic battery isolation tab, charge fully, install with the negative pole first, and secure the end cap with the key pointing to green. Whether teaching students, conducting meetings, exploring constellations, or entertaining children, these green laser pointers offer reliable visible beam performance with rechargeable convenience.
