Rechargeable 532 nm green laser pointer projects a visible beam up to 990 miles with rotatable pattern head
The Tonstep rechargeable pen emits a visible green beam at 532 nanometres for presentations, teaching and casual astronomy. It is designed for indoor screens and outdoor star pointing with a lightweight body that fits in a pocket or bag.
Charge the battery for three to four hours until the charger light turns green, then insert the cell with the negative end first so the positive end contacts the cap. Press the power button to activate the beam and rotate the front head to switch patterns; removing the head returns a single dot. Incorrect battery orientation or skipping the initial charge are the usual reasons the unit fails to turn on.
This pointer suits educators, speakers and hobbyists who need a portable green beam for slides or night‑sky reference. Buyers who require a higher output power, a different wavelength or a ruggedised housing for industrial environments should look at other models.
